SNAP-AIPM-3

Production Specification

SNAP-AIPM-3 analog input module helps you measure and control power usage in your facility. The SNAP-AIPM-3 simultaneously measures volts AC RMS and amps AC RMS for each of the three phases, using current transformers (CTs) with a 1-5 amp secondary.

The module calculates true power and volt-amps for each phase and, in addition, calculates true power sums for all three phases.

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-3 modules work with SNAP PAC brains and R-series controllers. They require brain firmware version 9.1b or newer and PAC Project 9.1a or newer.

Also see the SNAP-AIPM-3V module, which uses CTs with a 0.333 VAC secondary.

If you need to monitor single-phase power, use the SNAP-AIPM instead.

NOTE: SNAP-AIPM-3 modules manufactured before April 2011 had different input ranges (0-250 VAC and 0-10 A). Specs were changed to allow connection to electrical systems and equipment at higher voltages (for example, lighting systems at 277 volts) and to double the resolution of current inputs. Before wiring or scaling any SNAP-AIPM-3, check the input range printed on the module. Scaling examples are in the data sheet. Older modules can be exchanged for newer ones; contact Product Support for information or answers to questions.

Build your system in the SNAP I/O Configurator.

This document lists and describes all Opto 22 SNAP PAC System part numbers, including PAC Project software, SNAP PAC controllers, SNAP PAC brains, and SNAP I/O modules of all kinds. SNAP PAC mounting racks and SNAP power supplies are also listed.

SNAP Power Monitoring Modules Data Sheet

This data sheet describes the SNAP-AIPM, SNAP-AIPM-3, and SNAP-AIPM-3V analog input modules. These modules monitor AC voltage and current through a SNAP PAC rack-mounted controller or SNAP PAC brain.

The SNAP-AIPM monitors single-phase AC. The SNAP-AIPM-3 and SNAP-AIPM-3V monitor three-phase AC.

The SNAP-AIPM not only measures volts and amps simultaneously, but also calculates true power and volt-amps. From these values, you can easily calculate power factor. The SNAP-AIPM-3 and SNAP-AIPM-3V measure volts and amps and calculate true power and volt-amps for each of the three phases, and in addition calculate true power sums for all three.

Pulse Energy Quick Start

Pulse Energy is an online service you can use to view data about your electrical energy usage. Support for Pulse Energy is integrated into the OptoEMU Sensor™; however, if you are not using the Sensor but acquiring energy data using the SNAP PAC System, you can still see that data through Pulse Energy.

This sample chart shows you how to move data from PAC Control into Pulse. Import the included chart into your PAC Control strategy to make integration with a Pulse Energy account easier. The included technical note, form 1992, shows you how to configure a Pulse Energy account and use the chart to visualize your monitored energy values.
