I. Core Product Positioning

The ABB DDC779BE02 3BHE006805R0002 circuit board is a high-performance signal processing and interface card specially designed for industrial automation control systems. It is highly compatible with mainstream control systems such as ABB Symphony Plus and Advant OCS. Serving as the "signal interaction hub" in the system, it undertakes the tasks of collecting, conditioning, converting, and transmitting analog and digital signals from industrial sites. It can accurately connect sensors, actuators, and main controllers, providing reliable signal support for the stable control of complex industrial processes. It is an indispensable key hardware in large-scale automation systems in industries such as electric power, chemical engineering, and metallurgy.

II. Core Functions and Technical Advantages1. Efficient Processing of All Types of Signals

Multi-signal compatible acquisition: Supports 8 channels of analog input (AI), 16 channels of digital input (DI), and 8 channels of digital output (DO). The analog input is compatible with industrial common signals such as 4-20mA and 0-10V DC, adapting to various sensors for pressure, temperature, flow, etc. The digital input supports dry contact/wet contact signals, which can collect valve status, equipment start-stop feedback, etc. The digital output can drive actuators such as relays and indicator lights to realize the control of on-site equipment.
High-precision signal conditioning: Built-in with a 24-bit high-precision ADC (Analog-to-Digital Converter), the analog acquisition accuracy reaches ±0.1% FS, effectively reducing signal noise interference. Equipped with a digital filter circuit and a signal isolation module (isolation voltage 2.5kV AC), the common-mode rejection ratio (CMRR) is >80dB, which can maintain signal stability in strong electromagnetic interference environments and ensure the accuracy of collected data.
Flexible signal conversion: It can linearly convert the collected analog signals into digital signals recognizable by the main controller. At the same time, it supports the logical configuration of output digital signals (such as level trigger and edge trigger). According to on-site control requirements, the input and output logic of signals can be customized to adapt to the control logic needs of different industrial scenarios.

2. High Reliability and Environmental Adaptability

Industrial-grade hardware design: Adopts components with wide temperature tolerance ranging from -40℃ to +70℃. The PCB board uses FR-4 epoxy glass cloth substrate with a copper foil thickness of 35μm, which has excellent mechanical strength and heat resistance. Key solder joints adopt lead-free soldering process and pass the IPC-A-610 Class 3 acceptance standard, which greatly reduces the risk of cold solder joints and solder joint detachment, ensuring long-term operation stability.
Three-proof protection capability: The surface of the PCB board is coated with three-proof paint that meets the IPC-CC-830 standard, featuring moisture-proof, salt spray-proof, and mildew-proof properties. It passes the ASTM B117 salt spray test (≥48 hours) and the GB/T 2423.16 mildew test (Grade 0, no growth), and can adapt to harsh environments such as high humidity in coastal areas and corrosive gases in chemical workshops.
Anti-interference and stability: Passes the EN 61000-6-2 (industrial environment immunity) and EN 61000-6-3 (emission, Class B) electromagnetic compatibility tests. In scenarios with strong electromagnetic interference such as high-voltage equipment start-stop and inverter operation, signal transmission and processing are not affected, and the hardware failure rate is less than 0.1% per year.

3. Convenient System Integration and Maintenance

Standardized interface adaptation: Equipped with an ABB standard backplane bus interface, it can be directly inserted into the dedicated slot of the control cabinet of Symphony Plus and Advant OCS systems without additional adaptation circuits. It is automatically recognized by the main controller after power-on, shortening the integration cycle by 40% and reducing the complexity of system integration.
Visual status monitoring: The front of the board is equipped with 12 LED indicators, corresponding to power status (green), working status of each signal channel (green), and fault alarm (red) respectively. It can intuitively display whether the board is operating normally and whether signals are transmitted smoothly, enabling on-site personnel to quickly locate faulty channels and shorten troubleshooting time.
Support for online debugging: Compatible with ABB Control Builder M programming software, it can realize online parameter configuration (such as analog range calibration, digital trigger mode setting) and signal status monitoring through Ethernet or a dedicated debugging interface. No need to disassemble the board, reducing system downtime for maintenance.

4. Flexible Expansion and Redundancy Capabilities

Module expansion support: Reserves 2 expansion interfaces, which can be connected to external signal expansion sub-cards (such as an additional 8-channel AI expansion card and 16-channel DO expansion card). The number of signal channels can be flexibly increased according to on-site control requirements, with a maximum expandable capacity of 32 channels of DI, 16 channels of AI, and 16 channels of DO, adapting to automation systems of different scales.
Redundancy configuration compatibility: Supports 1+1 redundant installation, and can form a redundant group with another board of the same model. Data synchronization is realized through the backplane bus. When the active board fails, the standby board can automatically switch to take over the work within <50ms, ensuring uninterrupted signal processing and improving the overall availability of the system.

IV. Typical Application Scenarios1. Electric Power Industry

Thermal power plant auxiliary equipment control: Used for signal processing in auxiliary equipment systems such as boiler feed water pumps, induced draft fans, and forced draft fans in thermal power plants. It collects signals such as motor current, bearing temperature, and valve opening, converts them and transmits them to the main controller, and at the same time receives control commands to drive valve actions, ensuring the stable operation of the auxiliary equipment system and providing support for the normal combustion of the boiler.
Substation automation: Compatible with substation integrated automation systems, it collects signals such as transformer oil temperature, bus voltage, and circuit breaker status. Through high-precision conditioning and conversion, it ensures accurate data upload to the dispatching center. At the same time, it executes remote control commands to realize circuit breaker opening/closing and disconnector operation, improving the automation level of the substation.

2. Chemical Engineering Industry

Reactor control: Installed in the chemical reactor control system, it collects analog signals such as temperature, pressure, and liquid level inside the reactor, as well as digital signals such as the start-stop status of the stirring motor and the status of the feed valve. After processing, it feeds back to the main controller, helping to realize precise control of the reaction process and ensuring the stable quality of chemical products.
Pipeline transportation system: Used in the chemical raw material pipeline transportation system, it collects pipeline pressure, flow, and medium temperature signals, and monitors the operation status of the transportation pump. When the signal is abnormal, it triggers the alarm device or cuts off the power supply of the transportation pump through the DO channel, avoiding safety accidents such as pipeline overpressure and leakage.

3. Metallurgy Industry

Rolling mill production line: Compatible with the control system of the rolling mill production line in iron and steel plants, it collects key signals such as roll pressure, rolling temperature, and steel strip speed, providing accurate data support for rolling mill thickness control and speed adjustment. At the same time, it outputs control signals to adjust the hydraulic system and motor speed, ensuring that the rolling accuracy meets the requirements and improving the product qualification rate.
Blast furnace control system: Used in the blast furnace ironmaking control system, it collects signals such as blast furnace top pressure, hot blast temperature, and material level, and feeds back the internal working conditions of the blast furnace in real time. It assists the main controller in optimizing process parameters such as burden distribution and air supply, ensuring the stable operation of the blast furnace and reducing energy consumption and raw material consumption.
