ODULE
The YR40.242 is the preferred redundancy module for PIC480.241C power supplies. It is equipped with two input
channels (20A each), which are individually decoupled by utilizing MOSFET technology.
The output current can go as high as 40A.
Using MOSFETs instead of diodes reduces
the heat generation and the voltage drop
between input and output.
The YR40.242 does not require an
additional auxiliary voltage.
Due to the low power losses, the unit is very
slender and only requires 36mm width on
the DIN-rail.
See chapter 22.5 for instructions how to
build a redundant system.

The PIRD20.241 is a very cost effective diode 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.
If 20A power supplies are utilized, it is recommended to connect the power supply output to both inputs of the
redundancy module. Therefore, two redundancy
modules are required to build a 20A redundant power
system.
The PIRD20.241 is the perfect solution to use in a
redundant system, if the power
supply itself is equipped with a DC-
OK signal.
The PIRD20.241 does not require an
additional auxiliary voltage and is
self- powered even in case of a
short circuit across the output.
See chapter 22.5 for instructions
how to build a redundant system.
