SNAP Isolated Analog Input Modules
Description
The SNAP-AIARMS-i and SNAP-AIARMS-i-FM modules provide 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. These modules may also be used to monitor AC current to
greater than a 100-amp range, using a current transformer of suitable
ratio. The SNAP-AIARMS-i-FM module is Factory Mutual approved.
The two channels are isolated from each other; they do not share any
field connection. These modules are ideal for differential current
measurements.
