THÔNG TIN SẢN PHẨM

Features

• Overvoltage Protection can be up to 240 Vrms
• 8-channel Differential Analog Input
• Current, Voltage or Thermocouple Input
• 3000 VDC Intra-module Isolation
• Dual Watchdog
• Wide Operating Temperature Range: -25 to +75°C

Introduction

The I-7018/M-7018 is an 8-channel Analog Input module that provides current and voltage input, as well as thermocouple input. The I-7018R/M-7018R is an upgraded version of the I-7018/M-7018 that includes an extremely high-quality protection mechanism where the overvoltage protection can be as high as 240 Vrms. The I-7018R/M-7018R is more suitable for critically harsh environments, and the newly-added open thermocouple detection feature makes the I-7018R/M-7018R more attractive than ever. The I-7018/M-7018/I-7018R/M-7018R also features 4 kV ESD protection and 3000 VDC intra-module isolation. The specifications for the M-7018 and M-7018R are the same as the I-7018 and I-7018R, but provide additional support for the Modbus RTU protocol as well as the DCON protocol.
