Product Details

ABB MPRC086444-005 is a high precision measurement process board developed for ABB power electronics and generator excitation systems. The measurement process board completes high-speed synchronous acquisition of multi-channel analog signals such as voltage, current and frequency, and converts collected analog signals into digital data for real-time closed-loop control calculation. This ABB MPRC086444-005 board adopts galvanic isolation circuit and built-in signal filtering function, which effectively suppresses electromagnetic interference in power plant cabinets and improves signal sampling stability. The high precision signal processing board supports self-calibration and sensor loss detection, and built-in self-diagnostic function continuously monitors hardware status and signal channels, and outputs fault alarm information when abnormality occurs. The conformal coated circuit design can resist moisture and dust in harsh industrial environments. Widely used in UNITROL generator excitation systems, high voltage drives, substation automation and power quality monitoring equipment, it is key spare part for power control system maintenance and renovation. It adopts rack plug-in structure for convenient installation and quick field replacement.
