The 1756-RMS-SC module offers eight current and voltage input channel pairs with 250 Vac isolation, 16-bit resolution, fully linearized data and over/under range indication. The module calculates power factor using real, reactive, and apparent power measurements by sampling voltage and current. These power measurements are useful for glass furnaces, motor drives, pump systems, compressor systems, and conveyor belts. Other applications include building services, wind turbines, battery monitoring, solar power generation systems, and material processing.

The 1756-RMS-SC module allows the user to monitor power use at high update rates. The module also gives the programmable logic controller (PLC) control to maximize power usage without running the risk of damaging expensive equipment. With a full-featured add-on-profile, the module automatically populates information into the data table of the ControlLogix controller. This module is programmed using existing Studio 5000 programming software.
