IMPORTANT: The mounting rack connector has 24 pins; the
module connector has 20 pins. The extra pins on the
mounting rack connector prevent misalignment of the
module during installation.
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.
