Onboard voltage regulator chip, supports 7V ~ 36V wide range power supply and PoE power supply. Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal ^^ Supports passive and active digital input, with bi-directional optocoupler isolation, built in debouncing algorithm. The relay supports digital input linkage control or toggle control ^^ The output utilizes Darlington transistor with optocoupler isolation for stronger driving capability, up to 500mA sink current, and built-in flyback diode protection ^^ Features flash-on and flash-off functions, by passing arguments to the command, it is possible to turn on the output for a while and then turn it off automatically ^^ Rail-mount case design, easy to install, safe to use.
Onboard LEDs for indicating the input / output status, MCU status, and signal transceiving status
