Modul releu temporizare 5V 1 canal / Module time delay relay Arduino (r.2820S)

Specificații în limba engleză:

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.

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.

Product description:

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, the shortest is 0.1 second, and the longest is 1 hour;
6. The delay has a potentiometer adjustment, the clockwise adjustment time will be longer;
7. With power indication and delay switch indication;
8. The relay output has normally open and normally closed interfaces.

Features:

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 and the relay is closed.

1. Connect the 5V DC power supply to the module, and wait for the trigger terminal to see if there is a switch close 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 open;

3. When the module is triggered in the delay, if a trigger signal is received again, the module will re-time and automatically trigger the last time until the delay is over.

The trigger terminal can support the trigger delay of the following sensors:

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
8. Water level switch

Electrical parameters:

Power supply voltage: 5V, 12VDC
Quiescent current: 4.8mA Maximum power consumption: 70mA
Trigger time: 1ms or more is enough
Relay load capacity: 250V 10A AC 30V 10A DC (In actual applications, it is best to reduce the power by half, which is beneficial to prolong the service life of the product)
Relay life: 100,000 times (maximum power)

Selection method of delay time range:

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