British electricals provides multi-range timers [model tc-01]. Salient product features includes like selectable on/off delay, selectable time range [hr, min and sec], din rail mounting and screw mounting, slim space saving construction, etc. In off-delay mode when input power is applied timing begins and output relay gets energised. At the end of the preset time, the relay de-energises. The timer is reset when the input power is removed. In on-delay mode when input power is applied, timing begins during which the output relay remains de-energised. At the end of the pre-selected time, relay energises. The output relay is de-energised when power is removed, thus resetting the timer for the next cycle.
