    Applications Redundancy circuit for increased system availability SITOP PSE202U redundancy modules provide additional protection against the failure of 24 V supplies. By decoupling two power supplies through a redundancy module, a power supply that fails does not influence the 24 V supply. The redundancy module continuously monitors the feeding power supplies, and when one device fails, the other one automatically takes over the complete load circuit supply.
