Product Description

2 channel 5V 12V 24V Relay Module Red Board Optocoupler Isolation Output High Low Level Trigger Relay Module



Introduction:

Introduction to Relay Module:
The relay module is the function of the switch. The module supplies power, and the corresponding high/low level control signal is
input. The relay pulls in, and the COM terminal and the ON terminal are turned on to control the on-off of other circuits. It is
not the output voltage. The function of the switch is generally used for weak current to control strong current.

Module size:
1 channel: 50*25*18.5MM

2 channel: 50*41*17.5MM

4 channel: 75*51*16.5MM

8 channel: 142*52*18MM

Module interface:
1. DC+: connect to the positive pole of the power supply (the voltage is as required by the relay)
2. DC-: connect to the negative pole of the power supply

3. IN: high or low level control relay pull-in

Relay output:
1. NO: The relay is normally open, the relay is suspended before it is closed, and it is short-circuited with COM after it is
closed.

2. COM: relay common interface

3. NC: The relay is normally closed interface, the relay is short-circuited with COM before it is pulled in, and it is left in the
air after it is pulled in.

High and low level trigger selection terminal:
1. When the jumper is short-circuited with LOW, it is a low-level trigger;

2. When the jumper is short-circuited with high, it is triggered by high level.

Difference between with optocoupler and without optocoupler:
For the protection of the circuit, the safety with optocoupler is higher than that without optocoupler..
