Pilz lists 774502 as a standalone safety relay in the PNOZ XV2 family. It supports 1/2-channel wiring, can be used with or without detection of shorts across contacts, and is intended for monitoring emergency stops, safety doors, and similar machine-safety devices. The relay has UB = 24 V DC, integrated screw terminals, and a delay time adjustable in 12 steps from 0.1 to 3 seconds.
The output side combines 2 safety contacts and 2 delayed release contacts, which makes it useful when a machine needs both immediate safe shutdown and a short timed hold-off for process completion or controlled stopping. The module is 45 mm wide, with a listed height of 94 mm and depth of 121 mm, and has IP40 housing protection for panel installation. Typical use cases include E-stop circuits, safety gate interlocks, and contactor control in industrial machines.
