Overview: This product is a new digital LED countdown display 5V/12V delay module module. Using the high quality goods loose power relay military level double-sided PCB material, stable performance, widely with all sorts of control switch places. Product delay time can be set, can be set up key, set up after the electric start on the next according to the set value after the countdown. Products for accurate delay, error of 0.01% per second, delay time has three levels: 0.1 seconds, 1 second, 1 minute: 0-999 seconds every 1 SEC is adjustable, LED change every 1 seconds; Adjustable for 0.1 seconds from 0 to 99.9 seconds, LED changes every 0.1 seconds; The module is triggered by high level and the counting time is 0-999 seconds. This product has a wide range of applications and can be used in many fields. The product has low power consumption mode, long press the left button to turn off the digital tube display or start to display. Features: Power on, start delay, time is up, relay suction (work), power off disconnect. Switch on the power supply, relay snap-in (snap-in), start delay, time is up, relay disconnect. Switch on the power supply, start delay, time is up, relay suction (work), suction one period of time automatically disconnect. Switch on the power supply, relay suction (working) X seconds, disconnect Y seconds, infinite cycle. Switch on the power supply, relay suction (working) X seconds, disconnect Y seconds, finite cycle (set times). Signal trigger, relay suction, time to disconnect the relay, again in the delay period trigger invalid. Signal trigger, relay suction, time to disconnect the relay, in the delay period again triggered to retime. Signal trigger, relay suction, time to disconnect the relay, disconnect again in X seconds after the trigger is invalid. Signal trigger, relay snap-in, signal disappear, start timing, time to the relay disconnect, signal timing cancel during the delay, the relay remains snap-in. After N times of detection, the relay does not close until the power is cut off. The detection signal lasts for more than X seconds before the relay is sucked in and disconnected in Y seconds. The signal disappears and the time is cleared in less than X seconds. Specification: Material: Plastic Weight: 28g/1oz Current: Approx.12ma (standby); Approx. 50ma (when the relay is in operation) Size: 63.6*33.1mm/2.5*1.3inch Package List: 1 x Timer Relay
