Interface type: Standard RS-232 interface, which can realize serial communication with external devices such as computers, touch screens, other PLCs, etc

Communication protocol: It supports a variety of standard serial communication protocols, such as MODBUS RTU, etc., and can communicate with a variety of brands of equipment

Support a variety of baud rate options, usually including 2400, 4800, 9600, 19200, 38400, 57600, 115200bps, etc., which can be set according to actual communication needs

Generally, it is 1 start bit, 8 data bits, and 1 stop bit, which can be adjusted according to specific communication requirements

Supply voltage: Typically 5V DC power is provided by the connected CPU module, and the operating current consumption is small

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.

It meets the relevant electromagnetic compatibility standards, can work stably in a certain electromagnetic environment, and ensures the reliability and safety of the system.
