OPTO 22 - SNAP-AIPM _ Single-Phase Power Monitoring Module

Quick Specs:

Single-Phase Power Monitoring Module

SNAP-AIPM analog input module helps you measure and control power usage in your facility. The SNAP-AIPM module simultaneously measures single-phase volts AC RMS and amps AC RMS and calculates true power and volt-amps. Leading or lagging power factor can then be calculated from true power and volt-amp values.

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.

When these modules are used as part of a SNAP PAC System running a PAC Control strategy, the strategy logic can automatically perform the calculations and respond to problems.

Compatibility: SNAP-AIPM modules work with SNAP PAC brains and R-series controllers. They also work with legacy SNAP Ethernet-based brains.

NOTE: If you need to monitor 3-phase power, see the SNAP-AIPM-3 and the SNAP-AIPM-3V.

Build your system in the SNAP I/O Configurator.
