RAD-ISM-900-SET Wireless I/O Interface Transmitter Receiver Set Data sheet 2875_en_B 1 © PHOENIX CONTACT 2011-12-13 Description Unidirectional wireless systems comprise a transmitter (Tx) and a receiver (Rx). The transmitter accommodates two digital signals in the range from 5… 30 V AC/DC or 100… 240 V AC and one analog current signal (4… 20 mA). These signals are available for further processing at the receiver in the form of two relay contacts and one 4… 20 mA current output. In addition, a third relay in the receiver diagnoses the status of the wireless connection (RF link). The wireless connection is established automatically when the operating voltage UB is applied at both modules. When the connection has been established, the “RF-Link” LED is ON in the receiver and the RF link relay has picked up. From now on, data transmission occurs every 27 ms and the radio frequency is switched. The modules are supplied with a hopkey. Unique information about each wireless system is stored on the hopkey (the hop frequency used, the sequence, ID, etc.). done by assigning the hopkey of the existing receiver to the new receiver module. 1.1 Housing types Depending on the application, there are two housing types available for the transmitter: – DIN rail mountable housing for mounting in the control cabinet. – Rugged outdoor housing for direct mounting outdoors without an additional control cabinet. 2 – – – – Features 1 W transmitter Uses frequency-hopping, spread spectrum technology in the 902-928 MHz ISM band No programming required All modules are Class I, Division 2 Groups A, B, C, D listed In order to install another module in an existing wireless system, the module must be assigned to this system.

The device contains components that can be damaged or destroyed by electrostatic discharge. When handling the device, observe the necessary safety precautions against electrostatic discharge (ESD), in accordance with EN 61340-5-1 and IEC 61340-5-1. Observe the installation instructions for the antenna used. The antenna cable is plugged into the antenna connectors. 5.6 Function elements 5.6.1 Transmitter Display and diagnistic elements Display and diagnostic elements RF link relay The RF link relay in the receiver diagnoses the status of the wireless connection. It picks up when the wireless connection is established. If no data packets are received correctly over a period of approximately 4 seconds, the relay drops out. It picks up again automatically when the wireless connection is reestablished. The RF link relay functions as a PDT contact for the ME modules. Digital Output 1 LED = Status of digital output 1 Digital Output 2 LED = Status of digital output 2 RF-Link LED OFF = No operating voltage UB Flashes slowly = No reception Flashes quickly = Weak connection ON = Wireless connection established RSSI test socket A voltage measuring device (handheld multimeter) can be connected to the RSSI test socket to measure a voltage to ground, which provides information about the received wireless signal. Using Figure 4, the received signal strength, in dB, can be determined using the voltage value. This can be useful when positioning and aligning the antenna. Digital input 1 LED = Status of digital input 1 Analog inputs RSSI [V] Digital input 2 LED = Status of digital input 2 RF-Link LED On = operating voltage UB present, transmitter is sending data Receiver 4.5 4.0 3.5 3.0 2.5 2.0 1.5 1.0 0.5 0.0 1 Digital inputs Both digital inputs on the transmitter can process voltages from 5... 30 V AC/DC.

At the current source (terminal block 4), the actuator to be connected is wired to ground (terminal block 5). 5.7 Connection examples 5.7.1 Transmitter For notes on avoiding ground loops, see Figure 11. The output requires an internal drop voltage of 10 V. The maximum load at the current output with a nominal voltage of 24 V = (24 V - 10 V)/20 mA = 700 Ω. The maximum load therefore depends on the operating voltage UB used. +24 V GND 6 5 4 Digital outputs Two floating PDT contacts are used as the digital outputs for the receiver. 5.6.3 Behavior in the event of the wireless connection being interrupted RF 2 If the wireless connection is interrupted, all outputs (analog and digital) retain their last value or status (hold response, see “Connection examples). To configure a reset response (revert back to “0”) for a digital signal or the analog signal when a wireless connection is interrupted, connect the RF link relay contact in series, for example. 1 GND 4...20 mA Power +24 V 7 8 9 10 11 12 5...30 V AC/DC COM INPUT 2 To configure a reset response for all signals, use the RF link relay to control one or more additional relays.

These voltages may cause compensating currents over the low-resistance path marked red. Just a few volts can cause compensating currents in the range of several amperes, which may damage the module. used for the sensor and the RAD-ISM-900-SET… module, and when the two sources have a separate ground reference. This arrangement (using different sources for sensor and RAD-ISM-900-SET…) does not always cause problems. However, high compensating currents (in the range of several amperes) may cause damage to the module. To avoid these effects, the complete arrangement must only be grounded at one central point (e.g., not using the connection to ground connection 2). Figure 11 shows the course of the compensating currents, which is created when different supply voltage sources are 24 V DC 24 V DC GND GND Differential voltages between the potentials Ground connection 1 Ground connection 2 Internal connection with current-compensated choke Compensating currents POWER GND +24V OUT GND UB GND Internal connection RF 1 2 4 ... 20 mA sensor Output with external supply 4-20mA LOOP PWR IN GND DIGITAL IN 1 COM IN 2 101511A001 Figure 11 2875_en_B Avoiding ground loops PHOENIX CONTACT 10 RAD-ISM-900-SET NOTE: When using surge protection for the antenna cable, make sure that the ground connection of the surge protection solution has the same potential as the power supply ground connection (Ground connection 1 as shown in Figure 11). 5.7.4 internationally in Class I, Division 2 areas with hazardous gases. Signals from outside the hazardous area, as well as signals from Division 2, can be connected directly. Signals from Division 1 cannot be connected directly. They can only be connected via the appropriate barriers because the inputs are not intrinsically safe. Due to the limited transmission power, the wireless path itself may be led through Division 2. There are no restrictions here. Installation in the hazardous area WARNING: In potentially explosive areas, only snap on and connect cables when the power is disconnected. NOTE: Installation and startup must only be carried out by qualified personnel. The relevant countryspecific regulations must be observed.

Any number of additional receivers can be used. The modules are supplied without a hopkey. The hopkey contains the transmission frequencies used and the hop sequence. This information is required when installing an additional receiver in an existing system. 5. To install an additional receiver, proceed as follows: Open the housing of the receiver in the existing system by pressing both housing latches on the sides. Remove the electronics module from the housing (see Figure 13). At the bottom right on the PCB is a small PCB in a 10-position base – this is the hopkey. Remove the hopkey and insert it in the same position in the new receiver that you wish to install. RAD-ISM-900-RX (Order No. 2867047) When the supply voltage is connected, the information is transmitted from the connected hopkey to a non-volatile memory inside the module. This hopkey can then be used to “teach” other receivers. The hopkey can be stored in the last receiver. If no hopkey is connected, the information inside the module is used. 1. 3. J10562 P001.1 2. To protect the modules against ESD, the operating personnel must remove electrostatic discharge at appropriate points (e.g., control cabinet) before touching the modules. The existing system must have established a wireless connection. Disconnect the power to the existing system. Figure 14 6. 7. 8. Inserting the hopkey Close all the housing covers and reinsert the modules in the control cabinet(s). Reconnect the supply voltage – the additional receiver now receives the same information as the receiver in the existing system. Repeat the procedure for all additional receivers.

When installing the wireless modules, please refer to the instructions in the module-specific installation note. The TX modules are equipped with weather-proof housing and can be installed directly outdoors. They are mounted on 1/2-in. NPT conduit or pipe. The RX module is snapped onto a DIN rail within a control cabinet or control box. In the electrical system of the building, a 2-position disconnecting device must be provided to isolate the RX receiver from the supply circuit. NOTE: Electrostatic discharge! The RX device contains components that can be damaged or destroyed by electrostatic discharge. When handling the device, observe the necessary safety precautions against electrostatic discharge (ESD), in accordance with EN 61340-5-1 and IEC 61340-5-1. 6.5 Function elements 6.5.1 Transmitter Display and diagnistic elements RF-Link LED On = operating voltage UB present, transmitter is sending data The RF link relay in the receiver diagnoses the Analog input The 4... 20 mA analog input detects active and passive current sensors. For passive current sensors, the unregulated operating voltage UB is provided. Digital inputs Both digital inputs on the RAD-ISM-900-TX-DC transmitter can process voltages from 5... 30 V AC/DC. They have a common ground potential. In addition to the antennas included, other omni-directional and yagi-directional antennas are available in our range of accessories for optimizing the wireless path. A special pigtail (adapter cable) may be required, depending on the antenna selected (see “Ordering Data” on page 3). 6.5.2 Receiver Display and diagnostic elements RF link relay The RF link relay in the receiver diagnoses the status of the wireless connection. It picks up when the wireless connection is established. If no data packets are received correctly over a period of approximately 4 seconds, the relay drops out. It picks up again automatically when the wireless connection is reestablished. The RF link relay functions as a PDT contact for the ME modules. Digital Output 1 LED = Status of digital output 1 Digital Output 2 LED = Status of digital output 2 RF-Link LED OFF = No operating voltage UB Flashes slowly = No reception Flashes quickly = Weak connection ON = Wireless connection established Observe the installation instructions for the antenna used. The antenna cable is plugged into the antenna connectors. 2875_en_B PHOENIX CONTACT 16 RAD-ISM-900-SET RSSI [V] RSSI test socket A voltage measuring device (handheld multimeter) can be connected to the RSSI test socket to measure a voltage to ground, which provides information about the received wireless signal. Using Figure 4, the received signal strength, in dB, can be determined using the voltage value. This can be useful when positioning and aligning the antenna. 4.5 4.0 3.5 3.0 2.5 2.0 1.5 1.0 0.5 0.0 1 2 3 6.6 Connection examples 6.6.1 RAD-ISM-900-TX-DC transmitter For notes on avoiding ground loops, see Figure 11. 3.5 3.0 2.5 2.0 1.5 -120 -110 -100 -90 -80 -70 signal loss (-dB) Figure 18 RSSI diagram = No connection = Fair connection = Good connection 5…30 V AC/DC UB OG RD BK BU YE GY Analog outputs (also operating voltage) The analog output is supplied internally from the unregulated operating voltage UB. At the current source (pin 3), the actuator to be connected is wired to ground (pin 4). The output requires an internal drop voltage of 10 V. Figure 19 6.6.2 3-wire passive current sensor RAD-ISM-900-TX-AC transmitter For notes on avoiding ground loops, see Figure 11. The maximum load at the current output with a nominal voltage of 24 V = (24 V - 10 V)/20 mA = 700 Ω. The maximum load therefore depends on the operating voltage UB used. Digital outputs Two floating PDT contacts are used as the digital outputs for the receiver. 6.5.3 Behavior in the event of the wireless connection being interrupted If the wireless connection is interrupted, all outputs (analog and digital) retain their last value or status (hold response, see connection examples on page xx). To configure a reset response (revert back to “0”) for a digital signal or the analog signal when a wireless connection is interrupted, connect the RF link relay contact in series, for example. To configure a reset response for all signals, use the RF link relay to control one or more additional relays. 2875_en_B 85…240 V AC Neutral Line Figure 20 WH BK GN RD BU OG YE GY 2-wire passive current sensor PHOENIX CONTACT 17 RAD-ISM-900-SET 6.6.4 Installation in the hazardous area WARNING: In potentially explosive areas, only snap on and connect cables when the power is disconnected.
