Advantages and Key Features

1. All-in-One Integrated Solution: The ABB UFC721BE101 3BHE021889R0101 integrates the controller, power supply, communication, and a base set of I/O into one compact device, significantly simplifying cabinet design, reducing wiring, and lowering overall system cost.

2. Deterministic and Reliable Performance: As a dedicated process controller, it guarantees fast and predictable scan times for control loops and logic, which is essential for consistent product quality and process safety in continuous or batch operations.

3. Seamless Freelance DCS Integration: It is a native component of the Freelance system, offering a unified engineering and operator interface environment. This includes integrated configuration, debugging, diagnostics, and the automatic generation of process graphics (faceplates) from the control logic.

4. Flexible Connectivity: Its built-in PROFIBUS DP and MODBUS capabilities allow for easy integration of a wide array of field devices, remote I/O stations, variable speed drives, and third-party PLCs, making the ABB UFC721BE101 3BHE021889R0101 a versatile hub for plant floor communication.

5. Robust Design for Industrial Environments: Built to withstand typical industrial conditions with a wide operating temperature range and high immunity to electrical noise, ensuring reliable operation in demanding settings.

Application Case Studies

• Wastewater Treatment Plant: The ABB UFC721BE101 3BHE021889R0101 is used as the main controller for a sequencing batch reactor (SBR). It executes the timed sequence for fill, aerate, settle, and decant phases, controlling pumps, blowers, and valves via its onboard and expanded I/O, while communicating MODBUS data to the central SCADA.

• HVAC and Building Automation for a Large Facility: In a university campus, these controllers manage individual building heating and cooling plants. They run PID loops for temperature control, manage pump sequences, and provide alarm monitoring, all while being networked over Ethernet for centralized supervision.

• Small to Medium Batch Chemical Process: In a specialty chemicals unit, the controller manages a multi-step recipe-driven batch process. It handles analog control of reactor temperature and pressure, discrete sequencing of feed valves, and integrates safety interlocks, all within a single, cohesive programming environment.

Selection Suggestions and Important Notes

• Selection Suggestion:

  • Choose the ABB UFC721BE101 3BHE021889R0101 when you need a self-contained control solution for a process skid, subsystem, or small plant that benefits from the integrated engineering and operator tools of a DCS without the complexity and cost of a large system like 800xA.

  • It is an excellent choice for modernizing older loop controllers or small PLC systems where improved integration, diagnostics, and a unified operator interface are desired.

  • Select this controller when the application has a mix of analog and digital I/O that aligns well with its onboard capabilities, minimizing the need for immediate expansion.

• Important Notes:

  • I/O Capacity Planning: Carefully assess the onboard I/O of the BE101 variant against your application needs. Ensure there are sufficient channels of the correct type (e.g., analog inputs vs. outputs) before committing.

  • Expansion Planning: If expansion is needed, plan the PROFIBUS DP network topology, select compatible remote I/O (e.g., ABB’s S800 I/O with appropriate PROFIBUS adapter), and ensure the controller is configured as a DP master.

  • Software Licensing: The Freelance Engineering software requires appropriate licenses for configuration, simulation, and runtime. Ensure these are procured and correctly installed.

  • Firmware Updates: Always check for and install the recommended firmware for the UFC721BE101 to ensure stability and access to the latest features. The firmware must be compatible with your engineering software version.

  • Heat Dissipation: While robust, ensure adequate ventilation in the control panel, especially if the controller is installed in a high ambient temperature environment or alongside other heat-producing devices.
