Description
SNAP-AIARMS Two-channel 0 to 10 amp RMS AC/DC input
The SNAP-AIARMS module provides 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.
Specifications
The SNAP-AIARMS module may be used to monitor AC
current to greater than a 100-amp range, using a current
transformer of suitable ratio.
