22.2. YR20.242 - REDUNDANCY MODULE
The YR20.242 is a dual redundancy module, which can be used to build 1+1 or N+1 redundant systems.
The device is equipped with two input channels, each rated for 20A for ambient temperatures up to
+70°C and are individually decoupled by utilizing MOSFET technology. The inputs can also be
operated up to 24A when the ambient temperature does not exceed +45°C.
The output can be loaded with nominal 20A at +70°C or 24A at 45°C continuous current.
Using MOSFETSs instead of diodes reduces heat generation, losses and voltage drop between input
and output. Due to these advantages, the unit is very narrow and only requires 32mm width on the
DIN rail.
The device does not require an additional auxiliary voltage and is self-powered even in case of a short
circuit across the output.
See chapter 23.5 for wiring information.
