Modbus 4DI 4AI 4DO 2AO RS485 Ethernet Remote IO Module for Subway Rail

Industiral Automation 4DIN+4AIN+2AO+4DO Ethernet Remote IO Module for PLC Extension

There are many industrial automation devices such as PLC which have a MODBUS Communications facility available. PLC can be configured as a MODBUS Master, and IO modules are attached to the RS485 configured as RTU slaves. PLC system use M120 Modbus RTU IO Module to increasing the I/O capability of the industrial control system. The Modbus remote IO M120 also supports Modbus TCP server and client, SNMP V1/V2, and MQTT protocol. Which is suitable for wide range of industrial data acquisition and remote monitoring applications.

The M120 Ethernet Remote I/O module provides a RS485 interface, through the RS485 bus, it can cascade Modbus RTU I/O devices or Modbus RTU meters, e.g.: a variety of digital input or digital outputs, analog inputs or outputs, thermal resistance IO module combination, save costs. At the same time, the Ethernet Remote I/O module has register mapping function, the cascade Modbus RTU I/O data are automatically collected to the mapping memory area, the Modbus TCP Client query without waiting then can get a quick response to meet the industrial timely requirements.
