OPTO 22 - SNAP-AIVRMS-i-FM _ SNAP Isolated 2-Ch 0-250 V RMS AC/DC Analog Input Module, Factory Mutual Approved

OPTO 22 - SNAP-AIVRMS-i-FM _ SNAP Isolated 2-Ch 0-250 V RMS AC/DC Analog Input Module, Factory Mutual Approved

Quick Specs:

  • SNAP Isolated 2-Ch 0-250 V RMS AC/DC Analog Input Module
  • Factory Mutual Approved
The SNAP-AIVRMS-i-FM module provides two isolated channels with an input range of 0 to 250 volts AC or DC. The SNAP-AIVRMS-i-FM 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 Logix PLC system, such as ControlLogix, MicroLogix, or CompactLogix.

If you do not need isolated channels, see SNAP-AIVRMS.

The SNAP-AIVRMS-i-FM is Factory Mutual approved. If you do not need FM approval, see the SNAP-AIVRMS-i instead.

Build your system in the SNAP I/O Configurator.
