ME31-XAXA0404 4 analog output/ input supports Modbus The TCP/RTU protocol
[Introduction]：ME31-XAXA0404 is available with 4 analog outputs (0-20mA/4-20mA) and 4 analog (0-20mA/4-20mA) inputs and supports Modbus The TCP protocol or performs acquisition control, and the device can also be used as a simple Modbus gateway (automatically issues instructions for non-native Modbus addresses through serial/network ports)
