PWRM20-01

High-Accuracy, Rugged, Instrument Class®, Energy Monitoring Module

PWRM20-01
High-Accuracy, Rugged, Instrument Class®, Energy Monitoring Module

Description

The Energy Monitoring Module PWRM20-01 is an IoT universal, high-accuracy, compact, self-powered, electrical energy measurement device that interfaces to three-phase and single-phase systems. Specifically designed for industrial and commercial heavy-duty new and retrofit applications, the module provides a wide range of highly accurate power and energy measurement values over an operating temperature range of -40°C to +85°C.

The DIN-rail mounted enclosures have pluggable terminal blocks for connecting to phase voltages and phase currents which simplifies setup and maintenance, and the small format requires little space in control cabinets. The PWRM20-01 module interfaces to phase voltages of 85–525VAC, 50/60Hz, and is self-powered from any of the lines. Higher voltages can be interfaced to with the use of voltage transformers (VT) and appropriate scaling factors in the module.

Phase current inputs have an industry-standard range of 0.333VAC full-scale. An external shunt, current transformer, or Rogowski Coil is required to measure currents directly or non-contact.

BENEFITS
Measuring power quality, monitoring energy consumption, determining machine health, and performing other powerful data analysis turn into simple and easy operations with this user friendly and feature rich IoT energy monitoring module.

APPLICATIONS
  • Energy Metering Systems
  • Power Quality Monitoring

FAQ

Can LabVIEW be used to query data from PWRM10-01 and PWRM20-01 modules?

Real-time data from PWRM modules can be accessed via an Ethernet TCP/IP port using the HTTP API.  More specifically, any program or script that can issue and recive a response from a HTTP API GET request can communicate with PWRM modules.  LabVIEW provides a VI that can be used for this specific functionality:  https://www.ni.com/docs/en-US/bundle/labview/page/lvcomm/http_client_get.html.
