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.
