Detail 5v 4 channel level solid state relay SSR module high quality 5 volt High level / low level
5V Omron solid state relays 240V 2A, output with resistive fuse 240V 2A. Input power supply: 5V DC (160MA) Input control signal voltage: (0-2.5V low state relay OFF) (3.3-5V state high relay ON) Blue KF301 terminal connection control line is more convenient.
Module interface: DC +: positive power supply (by relay voltage power supply) DC-: connect power negative CH: Relay Module signal triggering end (high level /Low level trigger effective)
Note: Power must be DC voltage and need to be consistent with the voltage relay
