It is equipped with two input channels, which can be connected to power supplies with up to 10A output current and one output, which can carry nominal currents up to 20A. The module is suitable for power supplies with constant current overload behavior as well as any kind of “Hiccup” overload behavior. Input voltage Input voltage range Input current The YR2.DIODE is the perfect solution to use in a redundant system, if the power supply itself is equipped with a DC-OK signal (e.g.: DIMENSION Q-Series). In addition to the YR2.DIODE is the YRM2.DIODE which has a monitoring circuitry included. LEDs and relay contacts signal when one of the two DC-input voltages is not in range due to a non-functioning power supply. Another interesting application for this diode module is to separate sensitive loads from non-sensitive loads. This avoids the distortion of the power quality for the sensitive loads which can cause controller failures. Unique quick-connect spring-clamp terminals allow a safe and fast installation and a large international approval package for a variety of applications makes this unit suitable for nearly every situation.

INTENDED USE This device is designed for installation in an enclosure and is intended for commercial use, such as in industrial control, process control, monitoring and measurement equipment or the like. Do not use this device in equipment where malfunction may cause severe personal injury or threaten human life. The redundancy module can be used with any type of power supply as long as the maximum output current ratings are not exceeded. It is suitable for power supplies with continuous overload current as well as any kind of intermittent (Hiccup) overload behavior. 2. INSTALLATION INSTRUCTIONS WARNING - Risk of electrical shock, fire, personal injury or death. Turn power off before working on the device and protect against inadvertent re-powering. Do not open, modify or repair the device. Use caution to prevent any foreign objects from entering into the housing. Do not use in wet locations or in areas where moisture or condensation can be expected. Do not touch during power-on, and immediately after power-off. Hot surface may cause burns. Obey the following installation instructions: This device may only be installed and put into operation by qualified personnel. This device does not contain serviceable parts. The tripping of an internal fuse is caused by an internal defect. If damage or malfunction should occur during installation or operation, immediately turn power off and send unit to the factory for inspection. Install the device in an enclosure providing protection against electrical, mechanical and fire hazards. Do not ground or earth the positive output pole which could prevent redundancy in case of a ground failure. Ground the negative output pole, when needed. Use only power supplies with a negligible output ripple voltage in the low frequency range between 50Hz and 10kHz when used in marine applications according to the GL regulations. Install the device onto a DIN rail according to EN 60715 with the input terminals on the top of the device. Other mounting orientations require a reduction in output current. Make sure that the wiring is correct by following all local and national codes. Use appropriate copper cables that are designed for a minimum operating temperature of 60°C for ambient temperatures up to +45°C, 75°C for ambient temperatures up to +60°C and 90°C for ambient temperatures up to +70°C. Ensure that all strands of a stranded wire enter the terminal connection. The device is designed for pollution degree 2 areas in controlled environments. No condensation or frost is allowed. The enclosure of the device provides a degree of protection of IP20. The input must be powered from a PELV or SELV source or an “Isolated Secondary Circuit” in order to maintain a SELV or PELV output. Check correct input polarity. The device will not operate when input voltage is reversed. The device is designed as “Class of Protection III” equipment according to IEC 61140. A PE (ground) connection is not required. However, connecting the chassis ground terminal to ground can be beneficial to gain a high EMI immunity. The device is designed for convection cooling and does not require an external fan. Do not obstruct airflow and do not cover ventilation grid! The device is designed for altitudes up to 6000m (19685ft). See additional requirements in the product datasheet for use above 2000m (6560ft). Keep the following minimum installation clearances: 40mm on top, 20mm on the bottom, 5mm left and right side. Increase the 5mm to 15mm in case the adjacent device is a heat source. When the device is permanently loaded with less than 50%, the 5mm can be reduced to zero. The maximum surrounding air temperature is +70°C (+158°F). The operational temperature is the same as the ambient or surrounding air temperature and is defined 2cm below the device.

LIFETIME EXPECTANCY AND MTBF The redundancy module has two input channels which are completely independent from each other. Each control circuit, auxiliary voltage source, or other circuitry in the module are designed separately for each input. The dual input redundancy module can be considered as two single redundancy modules combined together in one housing. The only common point is the circuit trace that ties the two separate circuits together at the output. The MTBF figures below are for the entire dual input module. If the MTBF number of only one path is needed, simply double the value from the table. The redundancy module does not have electrolytic capacitors included. Therefore, the lifetime expectancy is extremely high. Input / output current conditions Lifetime expectancy *) MTBF **) SN 29500, IEC 61709 MTBF **) MIL HDBK 217F min. min.

It is the statistical representation of the likelihood of a unit to fail and does not necessarily represent the life of a product. The MTBF figure is a statistical representation of the likelihood of a device to fail. A MTBF figure of e.g. 1 000 000h means that statistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it can not be determined if the failed unit has been running for 50 000h or only for 100h.

ZM11.SIDE - SIDE MOUNTING BRACKET This bracket is used to mount the YR80 redundancy module sideways with or without utilizing a DIN rail. The two aluminum brackets and the black plastic slider of the unit have to be detached, so that the steel brackets can be mounted. For sideway DIN rail mounting, the removed aluminum brackets and the black plastic slider need to be mounted on the steel bracket.

APPLICATION NOTES 18.1. RECOMMENDATIONS FOR REDUNDANCY Recommendations for the configuration of redundant power systems: • Use separate input fuses for each power supply. • Use three-phase power supplies to gain functional safety if one phase fails. • When single-phase power supplies are utilized connect them to different phases or mains circuits if possible. • Set the power supply in “Parallel-Use” mode if this feature is available • It is desirable to set the output voltages of all power supplies to the same value. 18.2. INDUCTIVE AND CAPACITIVE LOADS The unit is designed to supply any kind of loads, including unlimited capacitive and inductive loads. 18.3. EXAMPLE: 1+1 REDUNDANCY UP TO 10A 1+1 Redundancy up to 10A requires two 10A power supplies and one YR2.DIODE redundancy module.

EXAMPLE: BATTERY BACK-UP A battery back-up with 10A requires one 10A power supply and one YR2.DIODE redundancy module. Please note: Set output voltage of power supply to 26.5Vdc minimum to ensure, that the load current is delivered from the power supply and not from charger (battery).

EXAMPLE: REDUNDANCY FOR CONTROLS The example shows a cost effective solution to get redundant power for a PLC or controller system. In many cases, two power supplies are used; one for the demanding loads and another one for the controls and sensitive loads. The power supply for the demanding loads can be used as a redundant source to supply the controls.
