Relay Module DC 12V With Optocoupler Relay Output 1 2 4 8 16Way Relay Module Control For dc5v dc12v 1 2 4 8 16 Way

DC 5V 12V Relay Module With Optocoupler Relay Output 1 2 4 8 16Way Relay Module For Arduino dc5v dc12v 1 2 4 8 16 way

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: 5VDC/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
