n5V solid state relays 240V 2A, output with resistive fuse 240V 2A.
nInput power supply: 5V DC (160MA)
nInput control signal voltage:
n(0-2.5V low state relay OFF)
n(3.3-5V state high relay ON)
nBlue KF301 terminal connection control line is more convenient.
nDC +: positive power supply (by relay voltage power supply)
nDC -: connect power negative
nCH: Relay Module signal triggering end (Low-level trigger effective)
nNote: Power must be DC voltage and need to be consistent with the voltage relay.
