2 Pcs DC 12V Time Delay Relay Module, Trigger Circuit Timer Timing Board with LED Indicator Display

The SMPS based power supply of these modern electronic devices is vulnerable to spikes in the mains line so it gives a time delay of one minute before applying power to the device. This prevents deleterious effects due to inrush current and spurious spikes at power on. Specifications: Operating voltage:12V Output capacity:can control the DC 30v/10A or AC 250v/10A equipment Quiescent current:20mA Service life:more than 100,000 times Operating temperature:-40-85 Delay Time Range: switch S1, S2, S4 to different positions, potentiometer can adjust different time range Module size: 56.5mm X29.5mm X 18.5mm / 2.22 1.16 0.73 inch(L * W * H) Operating Method: Put S1, S2, S4 in the proper position, adjust the potentiometer to adjust to the time you need. When the trigger end of the module senses that there is a momentary closing of the switch, the module starts the delay function, and at the same time the relay pulls in and the delay ends and the relay recovers. When the module is triggered for delay, if a trigger signal is received again, the module will re-time until the delay ends. We highly appreciate all customers opinions to improve the selling, also if anything you unsatisfied, please contact us for probable best solution. Package Includes: 2pcs
