SITOP PSE202U redundancy module input/output: 24 V DC/40 A suitable for decoupling two SITOP power supplies with maximal per 20 A output current *Ex approval no longer available* The SITOP PSE202U redundancy modules are the optimal addition to all 24 V power supplies to provide additional protection against a failure of the 24 V supply. The redundancy module decouples two 24 V power supplies of the same type up to a 20 A output current each, so that if one power supply fails, continued supply of the loads is ensured by the second power supply. In addition, a signal contact sends a signal, which can be evaluated by a controller, a PC or a control system. The redundancy modules also enable power supplies of the same type to be connected in parallel in order to increase the power. This also provides redundancy. Regardless of the industry or requirements, Siemens offers reliable and efficient power supplies for every plant.
