SNAP-AIARMS-I

SNAP-AIARMS-I is a SNAP isolated analog input module. It provides an input range of 0 to 10amps RMS AC/DC. An ideal input is the 5-amp secondary of a standard current transformer used to monitor AC line current. This module may also be used to monitor AC current to greater than a 100amp range, using a current transformer of a suitable ratio. The SNAP-AIARMS-i-FM module is factory mutual approved. The two channels are isolated from each other, this do not share any field connection. This module is ideal for differential current measurements.
