Three-phase Power Monitoring Module, 85-300 V RMS and 0-0.333 VAC CT Inputs for Each Phase ; SNAP-AIPM-3V analog input module helps you measure and control power usage in your facility. The SNAP-AIPM-3V module simultaneously measures volts AC RMS and amps AC RMS for each of the three phases, using current transformers (CTs) with a 0.333 VAC secondary. These CTs are safer and less expensive than CTs that output current. Using the data from the voltage and current inputs, the module then 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 RSLogix 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. Processor compatibility: SNAP-AIPM-3V 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. See compatible split-core CTs . Other power monitoring input modules: - SNAP-AIPM monitors single-phase power. - SNAP-AIPM-3 monitors three-phase power using CTs with a 1-5 Amp secondary. NOTE: SNAP-AIPM-3V modules manufactured before April 2011 had a different voltage input range (0-250 VAC). Specs were changed to allow connection to electrical systems and equipment at higher voltages (for example, lighting systems at 277 volts). Before wiring or scaling any SNAP-AIPM-3V, 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 .
