0 to 250 Volt RMS AC/DC Input Module

Description

The SNAP-AIVRMS module provides an input range of 0 to 250

volts AC or DC. The SNAP-AIVRMS module may be used to

monitor 120/240-volt AC/DC and 12/24/48-volt AC/DC

system voltage.

Terminals 3, 4, 7, and 8 share a common connection inside the

module. Make sure you observe polarity when connecting the

second channel. To avoid a potentially hazardous short,

double-check wiring before turning on the voltage to be

monitored.

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

form #1182, the SNAP Isolated Analog Input Modules Data

Sheet.
