Redundancy Module
The 1606-XLERED20 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 (158 °F) 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
(113 °F).
The output can be loaded with nominal 20A at +70 °C (158 °F) or 24A at 45 °C
(113 °F) 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 32 mm 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.
