12V Relay Module With Optocoupler Relay Output 4 Way Relay Module For Arduino

Description

Module Parameters:

• There are 4 fixing screw holes around the board, the hole diameter is 3.1mm, which is convenient for installation and fixing.

• The relay uses high quality Songle relay, single pole double throw. a common end, a normally open end, and a normally closed end

• Optocoupler isolation, good anti-interference

• Low level pull-in, high level release. The status indicator is on when the inverter is closed, and the status indicator is off when released.

• VCC is the system power supply, and JD_VCC is the relay power supply. Plug in the jumper cap

Electrical parameters:

• Supply voltage: 12VDC
• Current: greater than 100mA
• Load: 250V 10A AC or 30V 10A DC

Wiring instructions:

• VCC: system power supply positive
• GND: system power supply negative
• IN1--IN2: Relay Control Por
