The Square D Type JCK plug-in timer relay provides low-cost, reliable timing control in a compact housing. It operates in on-delay mode, initiating the timing cycle when input voltage is applied. The relay contacts change state after the set delay, and return to their original position when power is removed. The timing range is adjustable via thumb wheels on the top of the device, covering from 0.5 seconds to 999 hours.
This timer plugs into an 8501NR51 or 8501NR52 relay socket, which can be mounted on a 35 mm DIN track or directly on a panel. All wiring connects to the relay socket. The relay features double-pole double-throw (DPDT) contacts rated at 10 amperes resistive at 120 VAC and 240 VAC, and 3 amperes inductive at the same voltages. It is powered with 240 VAC at 50/60 Hz.
