Two independent Songle SRD-05VDC-SL-C relays on one opto-isolated board, so a 5V microcontroller can switch two separate mains or DC loads. Each channel has its own optocoupler, status LED and three-way screw terminal (NO / COM / NC) rated 10 A at 250 V AC or 10 A at 30 V DC. Inputs are active LOW and need 15-20 mA each, and the JD-VCC jumper can be pulled to run the coils from their own supply for full isolation.
Key features
- Two SRD-05VDC-SL-C relays, SPDT per channel
- 10 A at 250 V AC / 10 A at 30 V DC per contact
- Optocoupler on every input, LOW-level trigger
- Each input needs 15-20 mA of drive current
- JD-VCC jumper for a separate relay-coil supply
- Header is VCC / GND / IN1 / IN2
