Relay Module 3 Channel USB to CH340 Serial Control Relay Module Optocoupler Protection TYPEC Interface Module DSTURT30

1. USB serial port control relay, serial port control, , overcurrent protection2. USB serial port control relay, newly upgraded and advanced version, with new optocoupler protection circuit to prevent interference and highspeed transmission3. The output terminal of the relay can be regarded as an electronic switch, controlling the on and off of the circuit. There is actually no voltage output at the load end of the module.4. When there is no voltage in the relay coil, the relay does not pull in, and the common terminal (COM) is connected to the normally closed terminal (NC). When there is voltage, the relay pulls in, and the common terminal (COM) is connected to the normally open terminal (NO).5.
