or +/-25 mV Analog Input Module

The versatile SNAP-AITM-4i module provides four channels of analog input with an input range of ±150 mV, ±75 mV, ±50 mV, ±25 mV, or Type B, C, D, E, G, J, K, N, R, S, or T thermocouple, and each channel can be individually configured.

The module provides optical isolation, transformer isolation, and channel-to-channel isolation. Since the four channels on the module do not share any common connections, grounded sensors and field devices may be used with them.

SNAP-AITM-4i requires SNAP PAC racks, a SNAP PAC brain or R-series controller with firmware 9.1 or newer, and PAC Project 9.1 or newer.

For a similar module with just 2 channels, see the SNAP-AITM-i.

If you don't need channel-to-channel isolation, see the SNAP-AITM or the 8-channel SNAP-AITM-8.

Build your system in the SNAP I/O Configurator.
