SITOP PSE202U redundancy module input/output: DC 24 V/40 A suitable for decoupling two SITOP power supplies with a maximum output current of 20 A each. The SITOP PSE202U redundancy modules are the ideal addition to all 24 V power supplies to ensure additional protection against a failure of the 24 V supply. The redundancy module decouples two 24 V power supplies of the same type with up to 20 A output current each, so that if one power supply fails, the consumers are still supplied with power from the second power supply. In addition, signaling is provided via a signaling contact, which can be evaluated by a controller, a PC or a control system. Using the redundancy modules, power supplies of the same type can also be connected in parallel to increase performance and at the same time provide redundancy. No matter what industry, no matter what requirement - Siemens offers reliable and efficient power supplies for every system.
