Phoenix Contact PSR-PS20-1NO-1NC-24DC-SC Coupling relay Order No. 2700356
Product Overview
The Phoenix Contact PSR-PS20-1NO-1NC-24DC-SC (Order No. 2700356) is a compact, high-reliability safety coupling relay that provides galvanic isolation between a safety controller and high-power contactors or motor starters. Its single-pole normally-open (NO) and single-pole normally-closed (NC) forcibly guided contacts ensure mechanical interlocking for Category 4 / SIL 3 / PL e safety circuits. The spring-cage (SC) terminals enable tool-free wiring and vibration-proof connections, while the slim 6.2 mm housing saves DIN-rail space in both panel and remote I/O stations.

Key Features & Benefits
• 1 NO + 1 NC positively driven contacts – impossible for both to close simultaneously
• SIL 3 / PL e certified – IEC 61508, EN ISO 13849-1, UL 508
• 24 V DC coil with wide 0.7×…1.25× tolerance – reliable pickup in brown-outs
• 6 A switching capacity – drives large contactors directly
• 6.2 mm width – up to 165 relays per meter of DIN rail
• Spring-cage terminals – push-in wiring, vibration-proof, maintenance-free
• Integrated LED status – coil energized / contact position at a glance
• –40 °C…+70 °C operating range – suitable for outdoor cabinets
• UL, CE, ATEX Zone 2, IECEx, marine approvals – global acceptance
