[Communication interface]：RJ45, RS485
[Working voltage]：DC 8~28V
[Installation method]：Guide rail/screw
[Introduction]：ME31-XEXX0600 is a K-type thermocouple temperature acquisition module with 6-channel K-type thermocouple temperature acquisition function, supporting the acquisition of 2-wire K-type thermocouple temperature sensors. It also has a display screen to facilitate customers to debug configuration and view temperature on site. The module supports both network and RS485 communication interfaces, and supports Modbus TCP protocol or Modbus RTU protocol for acquisition. It can also be used as a Modbus gateway, automatically sending instructions from non-local Modbus addresses through the serial port/network port, supporting Modbus TCP and Modbus RTU protocol conversion, and conveniently expanding Modbus slave devices.
