The SITOP redundancy modules are the optimal extension for all 24 V power supplies to ensure additional protection from failure of the 24 V supply. The redundancy module continuously monitors the power supply units and, in the event that one unit fails, the other unit automatically takes over the 24 V power supply. With the SITOP PSE202U redundancy modules, a signal is additionally sent via a signaling contact that can then easily be evaluated by a controller, PC, or control system. With the SITOP RED1200 redundancy modules, this message can be implemented in the form of a missing signal from the defective power supply.
The redundancy module decouples two 24 V power supplies of the same type so that the loads are still supplied by the second power supply (1 + 1 redundancy) in case one of the two power supplies fails.
Redundancy modules support parallel switching of power supplies of the same type to increase performance while offering redundancy at the same time (N + 1 redundancy).
You can use the NEC Class 2 redundancy module to implement a redundant 24 V supply limited to an output power of 100 VA.
For redundant configuration of a 24 V supply, the redundancy module decouples two SITOP 24 V power supplies of the same type by means of diodes in parallel operation. Depending on the output current of the power supplies, 1 to 2 redundancy modules may be required.
Monitoring
The redundancy module continuously monitors the output voltage of the connected power supplies. The switching threshold of 20 to 25 V can be set on the device. A signal indicates if the output voltage of one of the two power supplies sinks to the set value or below.

The LED on the device and a changeover contact signal a faulty power supply.
