The tM-AD5 is an analog input module that includes 5 differential analog input channels and provides a programmable input range on all analog inputs (+/- 1 V, +/- 2.5 V, +/- 5 V, +/- 10 V). It provides a high overvoltage protection of 120 VDC. The sampling rate of the tM-AD5 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.
