Product Description:

Danaher’s HP515A6 belongs to the Timers and Controllers series. It functions as an industrial timing relay that sequences loads, disengages clutches, or coordinates process steps when precise short-interval control is required. The unit operates from a single-phase supply and opens or closes an external circuit after a selected delay. This action provides predictable timing during equipment startup, controlled shutdown, and other brief machine sequences.

The timer is powered directly from a supply of 120 VAC at 60 Hz, so no auxiliary transformer is required in common North American control panels. Its electromagnetic motor imposes a burden of only 2.45 VA, while the actuating clutch draws 10.5 VA. The output contacts support a maximum inrush and steady resistive current of 10 A at the supply voltage. The adjustable timing range extends from 1/3 second to 10 seconds, supporting short delays for conveyors, clamping fixtures, fluid valves, and clutch mechanisms. Settings are engraved in 1/6-second increments, allowing selected delay values to be reproduced consistently. Internal gearing maintains cycle-to-cycle repeat accuracy within ±0.05 second. The mechanism has a 28 ms pull-in time and a 17 ms drop-out time, minimizing latency between the electrical command and mechanical response.

Contact durability reaches 250,000 operations at full load, which supports frequent switching under the rated electrical demand. The low-energy switch design also provides a mechanical life of 5,000,000 cycles when carrying 1 A. Once a timing cycle ends, the mechanism returns to its initial state within a reset interval of 0.5 second, allowing another cycle to begin promptly. The unit weighs 2 lb 14 oz and can be installed on a light-gauge panel without additional structural bracing. Its compact timing range and rapid reset behavior make it suitable for machinery that requires coordinated delays without prolonged interruption of the operating sequence.
