ABB 3BHE037864R0101 UFC911 B101

The 3BHE037864R0101 UFC911 B101 is a control interface board for ABB ACS1000 medium voltage drive and AC800F UFC900 control platform. This 3BHE037864R0101 acts as the communication and I/O bridge between the drive power section and the master controller, equipped with 16 digital input and 8 digital output channels, powered by 24VDC. The 3BHE037864R0101 supports Ethernet and Modbus RTU communication, exchanging status signals, fault codes and control commands for drive startup, interlock and protection logic.

This 3BHE037864R0101 adopts conformal coated PCB to resist dust and humidity inside high voltage converter cabinets. Front LED indicators display power, link and channel fault status for rapid on-site diagnosis. It collects feedback from auxiliary contacts, temperature switches and safety interlocks, and sends relay drive signals to contactors and trip circuits. The UFC911 series is the core local interface module for the legacy ACS1000 MV drive control rack.

The 3BHE037864R0101 is widely used in medium voltage variable speed drives for fans, compressors and pumps in power plants, mining and oil & gas facilities. The ACS1000 with UFC900 control system has been discontinued by ABB. Most available 3BHE037864R0101 units are tested surplus spare parts for overhaul and emergency replacement of existing ACS1000 drive cabinets.
