Square D 9050JCK52V20 JCK Plug-In Timer, 10A, 0.3-30s Repeat Cycle, 120V AC/110V DC

9050JCK plug in timers are designed to provide low cost timing in a plug in housing. This timer has a repeat cycle timing mode. When input voltage is applied, the time delay T1 begins. When time delay T1 is complete, the timer relay contacts change state for time delay T2. This cycle repeats until the input voltage is removed. The trigger switch is not used in this function. Two dials are provided to allow the two repeat cycle timing ranges to be independently adjusted. The timing range of 0.3 to 30 seconds is easily adjustable with a knob on the top of the timer. This plug in timer plugs into an 8501NR51 or 8501NR52 relay socket. These relay sockets can be mounted on 35 mm DIN 3 mounting track or directly to a panel. All wiring is made to the relay socket. The DPDT contacts are rated 10 amperes resistive at 120 VAC, 240 VAC and 30 VDC, 3 amperes inductive at 120 VAC, 240 VAC and 30 VDC, 1/3 HP on the NC contacts at 120 VAC and 240 VAC, 1/2 HP on the NO contacts at 120 VAC and 240 VAC. This plug in timer is powered up with 120 VAC / 110 VDC. 9050JCK plug in timers are UL listed when the proper 8501NR relay socket is used, UL component recognized and CSA certified.
