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, 4 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.

Stan Wetmore –
Great little relay board. I use it on a Raspberry Pi at 3.3v with a logic level chip and it works great. I power the board with a 5v power supply. Considering the Covid19 issues it came very quickly.
