Module with 8 relays with optocoupler. The module has power and signal pins grouped on the board and next to the relay socket are the related screw terminals (NC, NO and COM). These relays allow the control of consumers up to 250VAC and 10A.
Specifications:
Supply voltage: 12VDC
Logic voltage: 12VDC
Actuation: Low Level, Active Low on pins IN1-IN8
Number of relays: 8
Total dimensions mm: 138 x 56 x 18.5mm
Mounting holes: 4 with a diameter of 3.1mm
Use:
The board works at a logical voltage of 12VDC, therefore it requires the removal of the VCC and JD-VCC jumper, and the 12VDC power supply will be made through the GND and JD-VCC pins (from the Jumper location).
In the diagram below, next to the jumper, the voltage is 12VDC, not 5V.
