The W – RC2 is a high accuracy digital timer. Recycle timer is designed to cycle a load on and off, or to cycle between the two loads. The ON and OFF cycles are independently adjustable. It can be easily adjust time unit (sec, min, hr) and time range between 1 and 999, when the supply voltage is applied the ON cycle begins timing, the relay energized. Upon completion of the delay, the relay de – energize, and the OFF cycle begins timing. The timer will continue cycling until the supply voltage is removed. The case can be mounted on a DIN rail 35 mm.
