4 channel 5V Relay Module With optocoupler for Arduino details

This Relay employs high quality relay with four channels input and four channels output. It can be connected to 250V/10A AC element or 24V/10A DC element to the maximum, therefore, it can be used to control lights, motors and etc.

The modularized design makes it easy to connect to Arduino expansion board. The output state of the relay is shown by a luminous diode for the convenience of application.

Module parameters:

1. Size: 75 mm (length) * 55 mm (width) * 19.3 mm (high)

2. Weight: 61 g

3. PCB color: blue

4. The board with four fixed screw holes all round, hole diameter is 3.1 mm, convenient installation and fixed

5. Loose relay, relay selection of quality single pole double throw. A common end and a beginning, a normally closed end

6. Optical coupling isolation, anti-interference performance is good

7. Low level off, released in high level. Suction state indicator right, release the state when the light is out

8. VCC for system power, JD_VCC power supply for the relays. The default 5 v relay, with jumper cap

9. Maximum output relay: 30 v / 10 a dc, ac 250 v / 10 a
