A breakout board with 4 channel 5V DC relay. The control signal is DC 5V - 7.5V. It can control 10A 250VAC, 10A 30VDC load.

Size: 70mm X 17mm X 20mm.

The major component is EL817 and SRD-DV5V-SL-C.

Features

  • Outputs have LED indicators.
  • The input can be directly controlled by MCU's IOs.
  • With optoisolators installed.
  • Use diode to protect
  • Response time < 20ms
  • Relay can operate more than 100 thousands times.
  • Four channels can be controlled at the as time.
  • Independent input/output power supplies.
