  • 1 RS485 Serial port, supports Modbus RTU Master or slave, can extend I/O modules

The M200T 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 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 M200T 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 M200T Ethernet Remote I/O module provides 2 analog outputs, 12-bit resolution, supports 0~10VDC signal output. All of the I/O with high sampling frequency and special filtering strategy to ensure it's reliable.
