Allen-Bradley 852S-NSA Solid State Timing Relay

Allen-Bradley 852S-NSA Solid State Timing Relay is a Bulletin 852S unit designed to mount on Type N relays, delivering a compact, solid-state on-delay timing function for industrial control circuits. It provides an adjustable timing interval in the 0.1 to 5 second range, enabling precise control of downstream devices such as contactors, valves, or alarms without moving parts, which reduces wear and maintenance. This timing relay uses solid-state electronics to provide reliable, repeatable delays in electrically noisy environments and is compatible with other Bulletin 852S components for panel-mount timing applications, making it well-suited for sequencing, interlock, and safe-operate timing schemes in conveyors, pumps, packaging machines, and other automated systems.
