Photocoupler isolation between input control signal and controlled power, isolation surge voltage up to 5000V.
Input signal turn-on voltage DC 3 to 32V, turn-off voltage DC 0 to 0.8V. LED indication for relay turn-on.
Output voltage range: DC 5 to 30V. Maximum on-state average current 10 Amp. Maximum on-state current 20 Amp (< 2 second). Non repetitive surge peak on-state current: 160 Amp (<400uS). Maximum on-state resistance 8 milliohms(0.008 ohm).
This is a simple and practical solid state relay module, which is very convenient to use, for Arduino, Raspberry Pi, ESP32, PLC or other projects. The GPIO of these controllers are directly connected to this relay input to control the 5 to 30V high current DC power.
Compact ABS plastic case and wires connect for easy mount. Two screw mounting holes are convenient for you to fix it on the wall or wooden board. Of course, you can also choose not to lock the screw.
