M240T - 4RTD Ethernet Input Module（2 or 3 wires PT100/PT1000）

The M240 Ethernet Remote I/O module provides 4 RTD inputs, supports PT100 and PT1000 resistance sensor, compatible with 2 or 3 wires, the resolution is 0.1°C. All of the I/O with high sampling frequency and special filtering strategy to ensure its reliable. 

Introduction

The M240 Ethernet Remote I/O Module is an industrial class, exceptionally reliable, highly stable and highly precise data acquisition module, it features an embedded 32-Bit High Performance Microprocessor MCU, Integrated 1/2 Industrial 10/100M adaptive Ethernet module inside. It provides multiple I/O, supports standard Modbus TCP, can be intergraded into a SCADA, OPC server, and other automated systems. It is designed for working in harsh industrial environments and is widely used in a variety of industrial automation, security monitoring systems, automatically measurement and control systems. 

The M240T 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 and 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 timing requirements.
