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.

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.

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.

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.

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.

Avoiding ground loops
NOTE:
Differential voltages may occur between the
potentials when the ground connections are
physically separated. 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).

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.

Additional receivers
4.
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.

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

OFF = No operating voltage UB
Flashes slowly = No reception

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.

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.

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
