Opto22 SNAP-AIVRMS-i

SNAP-AIVRMS-i SNAP Isolated 2-Ch 0-250 V RMS AC/DC Analog Input Module

The SNAP-AIVRMS-i module provides two isolated channels with an input range of 0 to 250 volts AC or DC. The SNAP-
AIVRMS-i module may be used to monitor 120/240-volt AC/DC and 12/24/48-volt AC/DC system voltage and is ideal for
differential voltage measurements.
 
The two channels are isolated from each other; they do not share any field connection.
 
Part of the SNAP PAC System, the module mounts on a SNAP PAC rack with a SNAP PAC brain or rack-mounted
controller. Analog, digital, and serial I/O modules can all be on the same rack. Such an I/O unit is also well suited for PC-
based control or for use as intelligent remote I/O for an Allen-Bradley RSLogix PLC system, such as ControlLogix,
MicroLogix, or CompactLogix.
 
If you do not need isolated channels, see SNAP-AIVRMS.
 
If you need a Factory Mutual-approved version, see the SNAP-AIVRMS-i-FM module instead.
