Allen-Bradley 700-HXM66SZ24 Multi-Function Digital Timing Relay

Allen-Bradley 700-HXM66SZ24 Multi-Function Digital Timing Relay is a compact, programmable timer in Rockwell Automation’s 700-HX family. It provides 1 timed SPDT contact rated at 5 A and operates from a 24 V DC control circuit, featuring no-voltage inputs for triggering. The unit supports 10 timing functions across multiple modes (N, F, C, K), enabling common timing behaviors such as on-delay, off-delay, one-shot, and repeat-cycle operation. Timing ranges span from 0.000 to 9999 hours, giving both short-duration and long-duration delays to suit diverse automation tasks. Typical applications include sequencing start/stop events on conveyors, interlock delays in packaging lines, batching timers in process control, and staged actuation of pumps, valves, or actuators in manufacturing environments. Designed for integration with standard Allen-Bradley relays and PLC I/O, the 700-HXM66SZ24 delivers deterministic timing in a small footprint suitable for panel-mounted control schemes.
