Solid State High Level 4 Channel 5V DC Relay Module - Black + Blue
Description: 5V Omron solid state relays 240V 2A£¬ output with resistance 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 trigger effective) Note: Power must be DC voltage and need to be consistent with the voltage relay
