SNAP-AIARMS-i SNAP Isolated 2-Ch 0-10 amp RMS Analog Input Module |
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 module is an
excellent choice for differential current measurements.
If you need Factory Mutual approval, choose the SNAP-AIARMS-i-FM instead.
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.
