Module parameters:

• Contact rating of Relay Module is 250V10A.
• Output of Relay normally open, normally closed;
• Active low. Voltage input of signal range: 0-5V;
• VCC is system power supply. JD-VCC is relay power supply. JD-VCC and VCC can be shorted.

• 2 channel with optocoupler relay module

• Size: 50.5mmx38.5mmx18.5mm

• Weight: 31g
• PCB Color: Black
• The board with four fixed screw holes,the diameter of hole is 3.1mm, easy to install and fixed.
• Optocoupler isolation, good anti-interference
• Low level is pull-in, high level is release. When the status is pull-in, the indicator is on,when the status is release, the indicator is off.
• VCC is system power supply, JD_VCC is relay power supply. Just need to Plug in the jumper cap.

Electrical parameters:

• Supply voltage: 5VDC, 12VDC
• Current: greater than 100mA
• Load: 250V 10A AC or 30V 10A DC

Wiring instructions:

• VCC: Positive of system power supply
• GND:negative of system power supply
• IN1 - IN2: relay control port
