The YRM2.DIODE is a redundancy module, which can
be used for various purposes. The most popular
application is to configure a highly reliable and true
redundant power supply systems. This redundancy
module has a monitoring circuitry included. 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.
Another interesting application is the separation of
sensitive loads from non-sensitive loads. This avoids
the distortion of the power quality for the sensitive
loads which can cause controller failures.
Alongside with the YRM2.DIODE, there exists the
decoupling module 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).
