1pcs 4 Channel 5V DC Relay Module Solid State High Level OMRON SSR AVR DSP for Arduino
Description:
5V  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 trigger effective)
Note:  Power must be DC voltage and need to be consistent with the voltage relay
