Eight opto-isolated channels on a 138 x 56 mm board, built for control panels rather than breadboards. This is the 12V-coil version, so the relay side wants a 12V supply while the inputs stay happy with 5V logic - each one triggers LOW and needs 15-20 mA. Every channel gives you NO, COM and NC on a screw terminal rated 10 A at 250 V AC or 10 A at 30 V DC, and the JD-VCC jumper lets the coils run from their own 12V rail.
Key features
- Eight SPDT channels, 10 A at 250 V AC / 10 A at 30 V DC
- 12V relay coils, about 30 mA each when energised
- Optocoupler and status LED per channel
- Active LOW inputs, 15-20 mA of drive each
- JD-VCC jumper separates coil power from logic power
- Board measures 138 x 56 mm
