Allen-Bradley 852S-A Solid State Timer Module

Allen-Bradley 852S-A Solid State Timer Module, Series G, is a compact solid-state timing relay designed to mount on Bulletin 700-N relays or function as a stand-alone timer in control circuits. It operates from 110–120 VAC line power and provides a normally open, sealed output capable of switching up to 300 VAC, enabling reliable delay control for higher-voltage loads. The timing range spans from 0.1 to 29 seconds, with timing accuracy typically within ±2% of the setting under constant voltage and temperature, making it suitable for precise ON‑Delay or OFF‑Delay sequencing. When used with Bulletin 700-N relays (2–4 poles), this module forms an integrated timer-relay assembly for compact panel enclosures, commonly applied to machine interlocks, process dwell times, conveyor sequencing, and other automation tasks that require repeatable, time-based actuation.
