The PSR-SCP-24DC/URD3/4X1/2X2/T2 safety relay is a contact extension block designed for use in safety circuits according to DIN EN 60204-1/VDE 0113-1, achieving safety category 3 per EN 954-1. It features four enabling current paths, one signaling current path, and one confirmation contact, with output contacts dropping after a 2-second delay per stop category 1. The device has a screw connection terminal block, operates with a 24 V DC supply, and has a housing width of 22.5 mm with dimensions of 22.5 mm × 114.5 mm × 99 mm. It supports a maximum switching voltage of 250 V AC/DC and a limiting continuous current of 6 A for normally open contacts. The relay is rated for operation in ambient temperatures from -20°C to +55°C, with IP20 protection for the housing and terminal blocks, and meets BG/TÜV and UL/CUL approvals.
