SNAP 2-Ch -20mA to +20mA Analog Current Input Module

The SNAP-AIMA provides two channels of -20 mA to +20 mA analog current input. The module does not supply loop excitation current. 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 that provides two isolated channels, see SNAP-AIMA-i.

For a module that provides two isolated channels and supplies loop excitation, see SNAP-AIMA-iSRC.

For SNAP PAC brains and rack-mounted controllers, we also have a four-channel module, the SNAP-AIMA-4, and a 32-channel module, the SNAP-AIMA-32.

Build your system in the SNAP I/O Configurator.
