OBSOLETE SNAP Isolated 2-Ch 0-10 amp RMS Analog Input Module
Data Sheet

Production Specification

*** NOTE: This part is OBSOLETE and no longer available. ***
Please consider SNAP-AIARMS-i or contact Opto 22 Pre-Sales engineers for more information. 

The SNAP-AIARMS-i-FM module provides two isolated channels with an input range of 0 to 10 amps RMS AC/DC. An ideal input is the 5-amp secondary of a standard current transformer used to monitor AC line current. The module may also be used to monitor AC current to greater than a 100-amp range, using a current transformer of suitable ratio.

The two channels are isolated from each other; they do not share any field connection. The SNAP-AIARMS-i-FM module is an excellent choice for differential current measurements.

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

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.

Build your system in the SNAP I/O Configurator.
