Allen-Bradley 700-HR52TA17 Timing Relay Module

Allen-Bradley 700-HR52TA17 Timing Relay Module is a tube-base, general-purpose dial timing relay that provides two timed contacts (DPDT) with no external voltage inputs, making it a self-contained timing element for control panels. It offers six timing functions and a dial-adjustable range from 0.05 seconds to 300 hours, enabling precise ON-delay, one-shot, and repeat-cycle sequencing in a compact form factor. The timer accepts either 100–240 V ac at 50/60 Hz or 100–125 V dc supply, with timing controlled entirely by its built-in dial settings for repeatable operation. Typical applications include motor-control sequencing, process timing, and interval control in industrial automation, where adjustable delays are required without external triggering signals.
