12V Normally Open Trigger Delay Relay Delay Circuit Module Vibration Alarm ModuleItem NO.: MK00869

12V Normally Open Trigger Delay Switch Relay Module

Product application:

This module is a delay module that uses button switches, touch switches, microswitches, and other normally open self reset switches for triggering. It can also be triggered using normally open sensors, such as vibration sensors, reed tubes, etc., to form a vibration alarm sensing device. Mainly used in machine equipment, automation equipment modification, PLC industrial control, vibration alarm settings, robots, intelligent products.

Product Introduction:

1. Adopting advanced and high-quality timing chips for accurate timing control;

2. Use high-power relays to control the load, with a maximum of 10A;

3. Equipped with anti power reverse protection diode, better protecting the module;

4. The triggering end adopts optocoupler isolation, with strong disturbance and interference ability to avoid false triggering;

5. It has 8 optional time ranges, with a minimum of 0.1 seconds and a maximum of 1 hour;

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

7. Equipped with power indication and delay switch indication;

8. The relay output has normally open and normally closed interfaces.

Function Introduction:

Introduction to the Normally Open Trigger Function: Before the module is triggered, the circuit at the trigger end is in an open circuit state. If there is an instantaneous switch closure or continuous closure, the module delay can be triggered, and the relay is closed

1. Connect the module to a 5V DC power supply and wait for the trigger end to receive a switch close trigger signal

2. When the triggering end of the module senses that a switch is closed and triggered, the module activates the delay function, and at the same time, the relay is closed, the delay ends, and the relay is disconnected;

3. When the module is triggered for a delay, if a trigger signal is received again, the module will timing again and automatically trigger the last time until the delay ends.

The triggering end can support the following sensor triggering delays:

1. Touch the switch lightly

2. Microswitch

3. Self reset switch

4. Normally open vibration sensor

5. Normally open reed tube

6. Normally open door magnetic sensor

7. Tilt sensing switch

8. Water level switch

Electrical parameters:

● Power supply voltage: 12VDC

● Static current: 4.8mA Maximum power consumption: 70mA

● Trigger time: 1ms or more is sufficient

● Relay load capacity: 250V 10A AC 30V 10A DC (in practical applications, it is best to reduce the power by half, which is beneficial for extending the product's service life)

● Relay life: 100000 times (maximum power)
