Phoenix Contact Redundancy module, TRIO-DIODE/48DC/2X10/1X20 Series

Using the redundancy module, it is possible for two power supply units of the same type connected in parallel on the,output side to increase performance or for redundancy to be 100% isolated from one another.

100% decoupling of power supply units connected in parallel
Reliable signaling of redundancy, the floating signal contact and LED immediately indicate the loss of redundancy
Load currents up to 30 A supported
Easy installation by snapping onto the DIN rail
Reverse polarity protection

The redundant systems are mainly used where the system places a high demand on operational reliability. The PSU must be big enough that the total current requirements of all loads are met by one power supply unit.
