Opto 22 SNAP-AITM Analog Input Module

The Opto 22 SNAP-AITM is an analog input module designed for use with SNAP PAC systems and SNAP I/O mounting racks. It provides 16 isolated analog input channels, each capable of measuring millivolt or thermocouple signals. This module is ideal for applications requiring high accuracy in data acquisition, temperature monitoring, or process control.

Each channel on the SNAP-AITM supports multiple thermocouple types (J, K, T, E, R, S, B, and N), with cold-junction compensation and linearization handled automatically by the system. The module is engineered for industrial reliability, offering galvanic isolation, noise immunity, and optically isolated inputs for robust signal integrity.

Typical applications include process automation, laboratory testing, environmental monitoring, and precision temperature measurement systems.
