New 2-channel 5V relay module with optocoupler isolation supports high and low level triggering of 5V

Product Introduction

One module description:

1. The module adopts genuine high-quality relays, with normally open interface load: AC 250V/10A, DC 30V/10A;

2. Adopting patch optocoupler isolation, with strong driving capability and stable performance; Trigger current 5mA;

3. The working voltage of the module is available in 5V, 9V, 12V, and 24V options;

4. The module can be triggered by setting high or low levels through jumper wires;

5. Fault tolerant design, even if the control line is broken, the relay will not operate;

6. Power indicator light (green), relay status indicator light (red)

7. The interface design is user-friendly, and all interfaces can be directly wired out through terminal blocks, which is very convenient

8. Module size: 50mm * 41mm * 18.5mm (length * width * height)

9. There are 4 fixed bolt holes with a diameter of 3.1mm and a spacing of 44.5mm * 35.5mm

Two module interface:

1 DC+： Connect the positive pole of the power supply (voltage according to relay requirements, with options of 5V, 9V, 12V, and 24V)

2 DC-： Connect the negative pole of the power supply

3 IN1： One signal trigger terminal, which can be set to high or low level to control the relay to close

3 IN2： 2-channel signal trigger terminal, can set high or low level control relay to close

Relay output terminal:

1 NO1： 1 relay normally open interface, suspended before closing the relay, short circuited to COM1 after closing

2 COM1： 1 relay common interface

3 NC1： 1 relay normally closed interface, short circuited to COM1 before relay closing, suspended after closing

4 NO2： 2-channel relay normally open interface, with the relay suspended before closing and short circuited to COM2 after closing

5 COM2： 2-channel relay common interface

6 NC2： 2-channel relay normally closed interface, short circuited to COM2 before relay closing, suspended after closing

Technical parameters

High and low level trigger selection terminal:

1. S1 is the high and low level trigger selection for one relay;

2. S2 is the high and low level trigger selection for 2-channel relays;

3. When com is short circuited to low, the corresponding relay is triggered at a low level, and when com is short circuited to high, it is triggered at a high level
