Allen-Bradley 700-PSBA1 Solid State Timer Relay

The Allen-Bradley 700-PSBA1 Solid State Timer Relay is a front-mounted, on-delay timing module that attaches to Bulletin 700-R or RM relays to deliver a precise 0.4–8.0 second delay for control circuits in industrial automation. It uses a self-contained front-panel potentiometer to set the timing interval and employs a solid-state timing circuit for repeatable, wear-free operation. Available in multiple line voltages, including 120V AC 60 Hz and 110V AC 50 Hz variants, the 700-PSBA1 provides a compact timing solution that can be paired with a 1–4 pole Bulletin 700-R/-RM relay to form a complete timing subsystem. With its input-triggered timing and adjustable delay, it suits start-up sequencing, interlocking, or delay-based control in machines and conveyors, where a defined output energization after the set interval is required. The module is designed to mount and operate as part of the Bulletin 700 timing family, offering straightforward setup and integration into existing Allen-Bradley control architectures.
