SIL842170 is a Celduc-relais 4‑pole AC semiconductor contactor designed to switch AC loads from 12 to 275 VAC with a rated output of 25 A. It uses a DC control input of 3–32 V and draws less than 10 mA to energize the load, enabling low‑power control from standard logic circuits. The module comes in a compact 22.5 mm pitch DIN rail‑mounting format for 4P configurations, ideal for panel installations. A typical application shown in the datasheet demonstrates driving a 4 kW resistive load at 230 VAC (AC‑51 category).
