YRM2.DIODE – (2x 10A Inputs, 1x 20A output)

The YRM2.DIODE is a dual redundancy module, which can be used to build 1+1 and N+1

redundant systems. It is equipped with two input channels, which are individually

decoupled by utilizing diodes.

The YRM2.DIODE does not require an additional auxiliary voltage and is self-powered even

in case of a short circuit across the output.

The YRM2.DIODE has a monitoring circuit included and is the perfect solution when the

power supply has no DC-OK function. Two LEDs and two relay contacts signal when one of

the two DC-input voltages is not in range due to a non-functioning or disconnected power

supply.

Due to the compact design, the unit is very slender and only requires 32mm width on the

DIN-rail.

YR40.482 – (2x 20A input, 1x 40A output)

The YR40.482 is a dual redundancy module, which can be used to build redundant

systems. It is equipped with two input channels, which are individually decoupled by

utilizing MOSFET technology.

Using MOSFET instead of diodes reduces the heat generation and the voltage drop

between input and output. The YR40.482 does not require an additional auxiliary voltage

and is self-powered even in case of a short circuit across the output.

Due to the low power losses, the unit is very slender and only requires 46mm width on the

DIN-rail.
