Four opto-isolated relay channels on one board - the usual choice once a project outgrows a single output. Each Songle SRD-05VDC-SL-C relay is rated 10 A at 250 V AC or 10 A at 30 V DC and brings out NO, COM and NC on its own screw terminal. Inputs IN1 to IN4 trigger on a LOW level and draw 15-20 mA each, and the yellow VCC / JD-VCC jumper lets you feed the relay coils from a separate supply so the coil noise never reaches your microcontroller.
Key features
- Four SRD-05VDC-SL-C relays, SPDT per channel
- 10 A at 250 V AC / 10 A at 30 V DC per contact
- Optocoupler and status LED on every channel
- Active LOW inputs, 15-20 mA of drive each
- VCC / JD-VCC jumper for an isolated coil supply
- Header is GND / IN1-IN4 / VCC
