OPT-SNAP-AIVRMS

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

The SNAP-AIVRMS provides two channels of 0-250 V AC or DC analog input. It may be used to monitor 120/240-volt
AC/DC and 12/24/48-volt AC/DC system voltage. Although the two channels are not isolated from each other, the
module is transformer isolated and optically isolated from other modules and devices.
 
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 need channel-to-channel isolation, see SNAP-AIVRMS-i.
