Protect your equipments with this tiny 12V time delay relay circuit. 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.
Technical Specifications:
Operating voltage:12V
Trigger: When the trigger end of the module senses that there is a switch closing trigger, the module starts the delay function, and the relay draws in. At the end of the delay, the relay is disconnected
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. The specific adjustment method is shown in the picture.
Module size: 56.5mm X29.5mm X 18.5mm / 2.22×1.16×0.73 inch(L * W * H)
Operating Method:
1. Put S1, S2, S4 in the proper position, adjust the potentiometer to adjust to the time you need.
2. 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.
3. When the module is triggered for delay, if a trigger signal is received again, the module will re-time until the delay ends.
Package Includes:
2 X DC 12v Delay Relay Switch
