Description

This relay board needs a power supply of 5VDC. The opto-insulated inputs can handle 3-24VDC control voltage, with a maximum input current of 22mA at 24VDC. A jumper can switch between 2 modes: If the jumper cap is set to VCC and JD-VCC, relays and opto inputs are using the same 5VDC power supply. If the jumper is open, a separated 5VDC power supply can drive the relays and the inputs are open for voltages up to 24VDC. The inputs are LOW-active. It means the output of a microcontroller (like Arduino or Raspberry) draws the input current to GND. The LOW level activates the relay, and a high level (or 3-state level) deactivates the relay.

Other relay modules with 1 relay, 2 relays and 8 relays are also available.

High-Current relay modules (30A) are available as well.

Finally, we offer relay modules for the ESP-01 IoT module, WeMos D1 Mini, remote-controlled relays, and a Wi-Fi 4-Channel relay DIY kit.
