Introduction

The tM-AD8 is an analog input module that includes 8 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). It provides a high overvoltage protection of 120 VDC. The sampling rate of the tM-AD8 is adjustable and is available in either fast or normal mode and It also provides 4 KV ESD protection as well as 2500 Vrms intra-module isolation.
