SNAP-AIMA-i

Availability: In stock
SNAP 2-Ch Isolated -20 mA to +20 mA Analog Current Input Module

Please call (800) 321-6786 to order.

Production Specification

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

If you also need built-in loop sourcing, see SNAP-AIMA-iSRC.

If you do not need channel-to-channel isolation, see SNAP-AIMA.

Build your system in the SNAP I/O Configurator.
