5V 2Ch Solid State Relay Module
5V Omron solid state relays 240V / 2A, output with resistive fuse 240V / 2A.
Control signal input voltage: (0-2.5V low state relay ON) (3-5V high state relay OFF)
Trigger current: 2mA
DC +: positive power supply (according to the relay voltage supply)
DC-: negative power supply
CH1-CH2: relay module signal triggering terminal (active low)
