Product Description
The WAGO 857‑354 Relay Module is a slim 6 mm DIN‑rail mount interface designed for versatile AC/DC control applications. With a universal 24 V AC/DC coil input and one changeover (SPDT) contact rated for 6 A continuous, it reliably switches both AC and DC loads. A yellow LED provides clear status indication, while Push‑in CAGE CLAMP® terminals enable fast, tool‑free wiring of 0.34 – 2.5 mm² conductors. Reinforced insulation between coil and contact, double insulation between like modules, and compliance with ATEX/IECEx make it suitable for safe operation in harsh industrial environments.
