WAGO 821-507 Interface Relay Module, 24 V DC, 1 Changeover Contact, Push-in CAGE CLAMP, Westnetz Compliant

Interface relay module with 1 changeover contact, engineered for reliable signal adaptation and isolation in industrial control systems. Its 24 V DC coil and push-in CAGE CLAMP® terminals enable fast, tool-free wiring, while the Westnetz-specific approval ensures compliance with German energy sector regulations (EnWG).

Advantages

Compact DIN-rail mountable design saves panel space. Push-in CAGE CLAMP® technology reduces installation time by up to 50% compared to screw terminals. LED status indication provides immediate visual feedback on coil energization. High dielectric strength of 4 kV between coil and contacts enhances safety in mixed-voltage environments. Silver nickel (AgNi) contacts offer excellent conductivity and long service life.
