Dataforth IoT Power & Energy Monitoring Module

The PWRM Energy Monitoring Modules are IoT, Universal, High Accuracy, Compact, Self-Powered, electrical energy measurement devices that interface to three-phase and single-phase energy systems. Specifically designed for industrial and commercial heavy-duty new and retrofit applications, the modules provide 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 phase voltage and phase current which simplifies setup and maintenance, and the small format requires little space in control cabinets. The PWRMxx modules interface to phase voltages of 85–265VAC or 85–525VAC, 50/60Hz, and are self-powered from any of the lines. Higher voltage applications can be addressed using voltage transformers (VTs) and appropriate scaling in the module. Phase current inputs have an industry-standard range of 0VAC to 0.333VAC. An external shunt, current transformer, or Rogowski Coil is used to measure currents directly or non- contact.
