특징
- Modbus RTU 4 Channel Relay Module 4CH Input Optocoupler Isolation RS485 MCU For Arduino
- Relay communication: multi-unit network 485 communication, based on MBDBUS-RTU protocol, the default communication address is 1, the user can modify the address by command
IN1 - IN4 are used by the switch. The status of the switch is read by 485, not by the input control relay output.
