The 777585 is a contact expansion block for Pilz PNOZ X safety relays, designed to increase the number of available safety output contacts without changing the core safety logic. The module accepts a 1‑channel safety input and delivers 4 N/O safety contacts rated for 24 VDC / 6 A and 240 VAC / 6 A, making it suitable for driving contactors, valves, and interlocking devices in machine‑safety circuits. The 2.5 W DC power consumption and compact 22.5 mm width allow it to fit even in dense PLC panels.
Mechanically, the unit has a 94×22.5×121 mm housing with IP‑40 protection, suitable for installation inside standard industrial control cabinets. The plug‑in screw‑type terminals simplify wiring and field replacement and support conductors from 24 to 12 AWG. The relay contacts are made of AgCuNi with an additional gold‑plating layer, enhancing reliability and contact life under typical safety‑relay switching loads. The module is commonly used in emergency‑stop circuits, guard‑door interlocks, and safety‑related contactor control where extra safety outputs are needed.
