The PS-RDN20 is a 20A redundancy
(buffering) module for a 24 Vdc power
system. Containing 2 sets of 20A OR-ing
diodes, the PS-RDN20 gives you a new
option for safe connection of 1+1 redundant
power supplies. Not only does it provide the
buffering and decoupling for redundant
power supplies, the PS-RDN20 also provides
alarm signals for both input channels
through the built-in alarm relays. Now you
can replace a failed power supply without
interruption to your control system.
