ABB 3BHE021889R0101 UFC721BE101 ADCVI Control Board

ABB UFC721BE101 with part number 3BHE021889R0101 is an ADCVI analog to digital conversion and control board for ABB Procontrol P14 control system. It collects multi-channel analog field signals, converts them into digital data and transmits to the main controller, and also processes control commands to output analog signals for closed-loop regulation.

This board adopts coated conformal treatment to resist moisture, dust and corrosion for harsh industrial environments. It supports backplane bus communication, with built-in channel diagnosis and fault alarm function. It is widely used as spare replacement parts for power plant excitation systems, metallurgy and heavy industry control cabinet maintenance and retrofit projects.
