USED PHOENIX CONTACT PSR-PS2

The Phoenix Contact PSR-PS20-1N0-1NC-24DC-SC is a designation associated with the PSR family of safe coupling relays, designed to couple digital output signals from failsafe controllers to I/O devices such as valves and actuators. These devices provide electrical isolation and power adaptation for functional safety applications and are rated for use in SIL (Safety Integrity Level) certified systems in accordance with IEC 61508. The PSR-PS2x series mounts on standard DIN rail and features force-guided contacts per IEC/EN 61810-3, an integrated test pulse filter, and a fixed screw terminal block connection. Suitable for emergency stop circuits, safety door monitoring, light grids, and Ex Zone 2 / Class I Div 2 hazardous area applications.
⚠ IMPORTANT: "PSR-PS2" is an abbreviated/partial model number. Phoenix Contact PSRmini coupling relays in this family include full catalog numbers such as PSR-PS20-1NO-1NC-24DC-SC, PSR-PS21-1NO-1NC-24DC-SC, PSR-PS22-1NO-1NC-24VDC-SC, and PSR-PS23-1NO-1NC-24VDC-SC. Please verify the complete catalog number from the product label before ordering or listing.
