Redundancy Modules
Available from stockArticle no.:A101.334
The PULS YR2.DIODE is a compact diode redundancy module for 12 to 48 V DC systems up to 20 A. It supports 1+1 and N+1 redundancy and is suitable for power supplies that already provide their own DC-OK signal. It can also electrically separate sensitive and non-sensitive loads to improve the stability of critical circuits. Spring-clamp terminals enable fast installation.

Description
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.
