The YRM2.DIODE is a redundancy module, which can be

used to build 1+1 and N+1 redundant systems. 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.

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.

In addition to the YRM2.DIODE is the YR2.DIODE which

has no monitoring circuitry included. This is the perfect

fit when the power supply itself is already equipped

with a DC-OK signal (e.g.: DIMENSION Q-Series).

Large screw terminals allow an easy installation and a

huge international approval package for a variety of

applications makes this unit suitable for nearly every

situation.
