Allen-Bradley 852S-NSC Solid State Timer

The Allen-Bradley 852S-NSC Solid State Timer is a compact solid-state timing relay that delivers a precise 1.0 to 60 seconds of delay to create controlled start-up sequences in industrial automation, and it is designed to mount with Allen-Bradley 852S relays as part of Bulletin 852S timing hardware, providing a solid-state alternative to mechanical timers for on-delay control. This NSC variant is part of the NSA/NSB/NSC family of solid-state timing units used with Type N relays, offering timing that is defined by electronic components rather than moving parts, with compatibility typically leveraged in retrofits and new installations within Rockwell Automation-driven control schemes. Typical applications include sequencing conveyors, machine start-up delays, process interlocks, and other control circuits where a defined delay after energization is required; the 1.0–60 s range is a core specification buyers search for when selecting a timing module, and this range supports simple to moderate delay needs in many manufacturing lines. Some distributor listings reference the 852S-NSC as a 'Series G' timer unit in the 852S CNC family, underscoring its role as part of a longer-running line of Allen-Bradley timing solutions that have historically accompanied Type N relays in automation architectures.
