ABB UFC719AE 3BHB003041R0001 I/O CONTROL BOARD IOEC
Description:
UFC719AE, with the order number 3BHB003041R0001, serves as the I/O control board for the ABB ACS 1000 medium-voltage frequency converter. The ACS 1000 is a standardized medium-voltage AC drive system designed specifically for three-phase power supply to squirrel-cage induction motors. It leverages proven microprocessor control technology to monitor the motor’s electromagnetic conditions in real time. When combined with Direct Torque Control (DTC) technology, these monitored data enable near-perfect sensorless motor control performance. With the addition of pulse encoder feedback, the system can be deployed in applications requiring precise speed regulation or long-term operation within the near-zero speed range. It is widely applicable to drive fans, water pumps, conveyors, compressors and other equipment across industries such as petrochemicals, mining, water resources, paper manufacturing and power generation.

The ACS 1000 frequency converter delivers a nearly sinusoidal output voltage, allowing it to be seamlessly integrated with standard induction motors currently in use without the need for derating. This makes it an ideal solution for retrofitting projects. The system is equipped with advanced local and remote control capabilities, with control components integrated inside the converter cabinet. It adopts full-digital, microprocessor-based technology to deliver process control, protection and monitoring functions, while also providing backup protection via dedicated hardware circuits.

Every unit of UFC719AE 3BHB003041R0001 comes with a built-in DC control voltage output, which can be used as a power source for digital input signals. The embedded circuit board features the model number 3BHB000272R0101. As an IOEC board, the UFC719AE is installed in the control unit of the ACS 1000. IOEC 1 is positioned at the center of the rotating unit, while Terminal X301 – which interfaces with DI 1.8 DISABLE LOCAL and AI 1.1 REFERENCE VALUE 2 – is located on the right side of the control unit. IOEC 2, IOEC 3 and IOEC 4 are also situated on the right side of the control unit. Wiring between the UFC719AE board and external devices can be performed when the rotating door is opened.
