This is a Modbus relay board. The RTU-RL812M is a slave Modbus device that uses two-wire RS-485 serial communication. It connects to an RS-485 network using Modbus RTU and ASCII protocols. The board features 8 relays, which can be configured to operate in three different modes: on/off mode, timer mode, and pulse width modulation mode. All registers are managed through serial communication. Users can define the power-on state and communication failure state of the relays.
The new firmware v2.00 has been released, allowing customers to upgrade their boards. For more features, please refer to the manual.
