The M120E Ethernet Remote I/O Module is an industrial class, isolated designed, high reliability, high stability and high precision data acquisition module, embedded 32-Bit High Performance Microprocessor MCU, Integrated 1-2 Industrial 10/100M adaptive Ethernet module inside. It provides multi I/O, supports standard Modbus TCP, can be intergraded into SCADA, OPC server, and other automation systems. It is design for working in the harsh industrial application environment, widely used in a variety of industrial automation, security monitoring system, automatically measurement and control system.

The M120E 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.
 
The M120E Ethernet Remote I/O module provides 4 optical-isolated digital inputs, supports max. 700KHz high speed pulse counter, 4 isolated 12bits analog inputs, supports 0~5V,0~10V,4~20mA,0~20mA analog signal, 4 digital outputs, supports 10Hz~300KHz high speed pulse output or relay outputs, 2 channel 12bits analog outputs, supports 0~10VDC signal output. All of the I/O with high sampling frequency and special filtering strategy to ensure it's reliable.
