PSR-PS20-1NO-1NC-24DC-SC PHOENIX CONTACT Safety Coupling

Review PHOENIX CONTACT Safety Coupling Relay 250v-ac

The Phoenix Contact PSR-PS20-1NO-1NC-24DC-SC safety coupling relay is a versatile and essential component in electrical systems that require reliable protection against fault currents. This 24V-DC operated, 250V-AC rated safety relay is specifically designed to ensure safe operation by disconnecting the load from the power source in case of a fault condition.

The PSR-PS20-1NO-1NC-24DC-SC is a contactless, optically isolated, and hermetically sealed relay, which guarantees high levels of safety and reliability. Its contactless design ensures that there is no electrical contact between the relay coil and the contacts, reducing the risk of arcing and sparking, thus preventing potential hazards.

This safety coupling relay features one normally open (NO) contact and one normally closed (NC) contact. The NO contact is rated for a maximum contact voltage of 250V-AC and a contact current of 2A, while the NC contact is rated for a maximum contact voltage of 250V-AC and a contact current of 5A. The device is designed to operate with a maximum current of 20A and a maximum power consumption of 0.5W.

The PSR-PS20-1NO-1NC-24DC-SC safety coupling relay is equipped with a visual fault indicator, which illuminates in case of a fault condition. This feature allows operators to quickly identify and address any issues, helping to prevent potential downtime and ensure safe and efficient system operation.

The device is designed to meet the requirements of various safety standards, including IEC 60947-5-2 and EN 50200. Its compact size, measuring just 67mm x 41mm x 21mm (W x H x D), makes it a space-saving solution for a wide range of applications.

The Phoenix Contact PSR-PS20-1NO-1NC-24DC-SC safety coupling relay is suitable for use in various industrial automation applications, such as machine safety, process control, and power distribution systems. Its robust design, high reliability, and easy-to-use features make it an ideal choice for applications where safety and reliability are paramount.
