The SNAP-AITM-2 provides two channels of analog input with a range of -50 to +50 mV, -25 to +25 mV, or type B,C,D,G,N,T,R, or S thermocouple. Use isolated probes for thermocouple inputs. Although the two channels are not isolated from each other, the module is 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 offering eight channels, see SNAP-AITM-8.

For a similar module with channel-to-channel isolation, see SNAP-AITM-i.

Build your system in the SNAP I/O Configurator.
