OPTO 22 – SNAP-AITM-i _ SNAP 2-Ch Isolated Type E,J, or K Thermocouple Analog Input Module

OPTO 22 – SNAP-AITM-i _ SNAP 2-Ch Isolated Type E,J, or K Thermocouple Analog Input Module

Quick Specs:

  • SNAP 2-Ch Isolated Type E
  • J
  • or K Thermocouple Analog Input Module

The SNAP-AITM-i provides two isolated channels of analog-to-digital conversion. Each channel can be configured for -150 to +150 mV DC, or -75 to +75 mV DC, or for type E, J, or K thermocouple operation.

In addition to having two channels isolated from each other, the module is also transformer isolated and optically isolated from other modules and devices.
Part of the SNAP PAC System, the module mounts on a SNAP PAC rack with a SNAP PAC brain or rack-mounted controller. Analog, digital, and serial I/O modules can all be on the same rack. Such an I/O unit is also well suited for PC-based control or for use as intelligent remote I/O for an Allen-Bradley Logix PLC system, such as ControlLogix, MicroLogix, or CompactLogix.

For a similar module with 4 channels, see the SNAP-AITM-4i If you do not need channel-to-channel isolation, see SNAP-AITM or SNAP-AITM-8.

Build your system in the SNAP I/O Configurator.
