0 to 10 Amp RMS AC/DC Input Module

Specifications

Description

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.

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.

If you need a module with channel-to-channel isolation, see

form #1182, the SNAP Isolated Analog Input Modules Data

Sheet.

Wiring diagrams are on the following page.
