High-Quality DC 12V Timer Relay Module For Delayed Switching On/Off Adjustable Delay Timer Control

This module is a delay module that uses key switches, touch switches, micro switches, and other normally open self-reset switches to trigger. It can also be triggered by normally open sensors, such as vibration sensors, reed switches, etc. It can form a vibration alarm sensing device. Mainly used in machinery and equipment, automation equipment modification, PLC industrial control, vibration alarm settings, robots, intelligent products.

 1. Using advanced high-quality timing chip control, accurate timing;

 2. Use high-power relay to control the load, up to 10A;

 3. It has a protection diode to prevent the power connection from being reversed to better protect the module;

 4. The trigger terminal adopts optocoupler isolation, which has strong interference and interference ability and avoids false triggering;

 5. With 8 optional time ranges, as short as 0.1 seconds, as long as 1 hour;

 6. The delay has a potentiometer adjustment, the clockwise adjustment time will be longer;

 7. With power indication and delay switch indication;

Normally open trigger function introduction: Before the module is triggered, the circuit at the trigger end is in an open state, if there is an instantaneous switch closure or continuous closure, the module can be triggered to delay the relay, and the relay is closed.

1. The module is connected to the DC power supply and waits for the trigger terminal to see if there is a switch closed trigger signal

2. When the trigger terminal of the module senses that the switch is closed, the module will start the delay function, and the relay will be closed at the same time, and the delay will end, and the relay will be disconnected;

1. Touch the switch

2. Micro switch

3. Self-reset switch

4. Normally open type vibration sensor

5. Normally open reed switch

6. Normally open door magnetic sensor

7. Tilt sensor switch

Power supply voltage: 12VDC

Quiescent current: 4.8mA Power consumption: 70mA

Trigger time: more than 1ms is enough

Relay load capacity: 250V 10A AC 30V 10A DC (The actual application power is halved, which is beneficial to prolong the service life of the product)

Switch S1.S2.S4 to different positions to select different time ranges, and the potentiometer is to adjust the time within the corresponding range
