The YR2.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 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.
