As a key component in ABB’s Freelance DCS system, it bridges field devices and central control systems, enabling real-time monitoring and control of diverse process variables.

This module combines robust processing power with extensive I/O capabilities, making it suitable for applications ranging from building automation to industrial manufacturing. The DDC779CE102 3BHE027859R0102 executes advanced control algorithms—including PID, fuzzy logic, and sequential control—while maintaining seamless communication with supervisory systems. Its scalable design allows integration into both small-scale control loops and large distributed networks, providing consistent performance across various industrial environments.

Core advantages and technical highlights

High-speed processing: Equipped with a 168 MHz ARM Cortex-M4 processor, the DDC779CE102 3BHE027859R0102 processes 10,000+ I/O points per second. In a semiconductor cleanroom, this speed enabled simultaneous regulation of 20 temperature zones with ±0.1°C accuracy, critical for wafer production yield.

Multi-protocol compatibility: Support for BACnet/IP, Modbus TCP, and Profinet ensures interoperability. A pharmaceutical plant used the module to connect legacy Modbus sensors with a new BACnet-based building management system, avoiding costly hardware replacements and reducing integration time by 40%.

Redundant architecture: Optional dual power supplies and communication ports minimize downtime. A data center leveraged this feature to maintain uninterrupted cooling control during a power supply failure, preventing server overheating and potential data loss.

Edge computing capabilities: Onboard 2 GB flash storage enables local data logging and analytics. A food processing plant used the DDC779CE102 to store 30 days of temperature and pressure data, facilitating compliance with FDA regulations and enabling root-cause analysis of process deviations without relying on cloud connectivity.

Typical application scenarios

Industrial HVAC: In a large automotive factory, the DDC779CE102 3BHE027859R0102 controls heating, ventilation, and air conditioning across 12 production zones. It adjusts airflow rates based on occupancy sensors (digital inputs) and temperature readings (analog inputs), reducing energy consumption by 18% compared to legacy systems. Its Ethernet/IP connection to the plant’s SCADA system allows centralized monitoring of HVAC performance.

Water treatment: A municipal wastewater treatment plant uses the DDC779CE102 to automate filtration and chemical dosing. Analog inputs monitor turbidity and pH levels, while analog outputs regulate dosing pumps. Sequential control logic triggers backwash cycles based on pressure differentials, ensuring filter efficiency. The module’s Profinet interface connects to variable frequency drives (VFDs) controlling pumps, enabling smooth speed adjustments and energy savings.

Building automation: A luxury hotel complex employs the DDC779CE102 3BHE027859R0102 to manage lighting, climate, and security systems. Digital outputs control lighting circuits based on occupancy, while analog outputs adjust room temperatures via thermostats. BACnet/IP communication integrates with the hotel’s property management system, allowing guest-specific climate settings and reducing energy waste in unoccupied rooms.
