tM-AD8C

  • 8-channel Single-ended Inputs
  • Current Inputs
  • Adjustable Sampling Rate
  • Dual Watchdog

Introduction

The tM-AD8C is a current input module that includes 8 single-ended analog input channels and provides a programmable input range on all analog inputs (0 ~ 20 mA, 4 ~ 20 mA). The sampling rate of the tM-AD8C is adjustable and is available in either fast or normal mode. It also provides 4 kV ESD protection as well as 2500 Vrms intra-module isolation.
