EBYTE ME31-XDXX0400 Temperature Acquisition Module 4-way PT100 RTD Ethernet RS485 With OLED Display Screen Support Modbus

ME31-XDXX0400 4-way temperature acquisition module PT100 thermal resistor RS485 network port to Modbus K-type thermocouple [Communication interface]：RJ45, RS485 [Working voltage]：DC 8~28V [Installation method]：Guide rail/screw [Introduction]：ME31-XDXX0400 is a PT100 thermal resistor temperature acquisition module with 4-channel PT100 temperature acquisition function, and supports the acquisition of 2/3-wire PT100 temperature sensors. It also has a display screen to facilitate customers to debug and configure on-site and view the temperature. This temperature acquisition 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 convenient for expanding Modbus slave .
