Module RS-485 Modbus RTU 2 kênh đầu vào tương tự AI ICP DAS tM-AD2 CR

Features

  • 2-channel Single-ended Inputs
  • Voltage Inputs and Current Inputs
  • Adjustable Sampling Rate
  • Dual Watchdog

Introduction

The tM-AD2 is an analog input module that includes 2 single-ended analog input channels and provides a programmable input range on all analog inputs (0 ~ 500 mV, 0 ~ 1 V, 0 ~ 2.5 V, 0 ~ 5 V, 0 ~ 10 V, 0 ~ 20 mA, 4 ~ 20 mA). It provides high overvoltage protection of 120 VDC. The sampling rate of the tM-AD2 is adjustable and is available in either fast or normal mode. It also provides 4 kV ESD protection as well as 2500 VDC intra-module isolation.

Applications
