M340T - 8RTD Input Module (2 or 3 wires PT100/PT1000)

The M340 Industrial Ethernet Remote I/O module provides 8 RTD inputs, supports PT100 and PT1000 resistance sensor, compatible 2 or 3 wires, the resolution is 0.1°C.

Introduction

The M340 Industrial Remote I/O Module is an industrial class, exceptionally reliable and very 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 SCADA, OPC server, and other automation systems. It is designed for working in harsh industrial environments and is widely used in a variety of industrial automation, security monitoring system, automatically measurement and control system. 

The M340 Industrial 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. 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.
