Interface type: Standard RS485 interface with isolation function, which can effectively prevent electrical interference and ensure the stability and reliability of communication.

Communication protocols: It supports a variety of RS485-based communication protocols, such as MODBUS RTU, etc., and can interact with a variety of devices that support RS485 communication.

Typically 5V DC power is provided by the connected CPU module, which consumes a small operating current and does not burden the CPU's power supply.

Operating temperature: standard temperature range of 0°C to +55°C when installed horizontally; The wide temperature range is -20°C to +70°C, and the I/O is derated by 75% at 60°C to 70°C. The standard temperature range is 0°C to +40°C when installed vertically; Wide temperature range from -20°C to +40°C.

Storage temperature: -40°C to +70°C.

Relative humidity: 95% max, non-condensing.
