DFC 01 37261-4-0369529 ABB Bailey

Product Dimensions：

The DFC 01 module is part of the legacy Bailey Controls ecosystem, which was later acquired by ABB. It is engineered to operate within a standard Bailey functional unit frame or cabinet. The module's primary role is to execute control strategies and facilitate communication between the central control system and field-level instrumentation. It is characterized by its high reliability and its ability to handle complex control loops in demanding environments such as power plants and chemical processing facilities.

Product Specifications

The technical parameters of the 37261-4-0369529 variant include specific electrical and physical characteristics suited for backplane integration.

• Manufacturer: ABB (formerly Bailey Controls)

• Series: INFI 90 / Network 90

• Module Type: Digital Field Controller (DFC)

• Power Requirements: Typically draws power from the system backplane, usually $+5 \text{ VDC}$ and $+/- 15 \text{ VDC}$ depending on the specific chassis configuration.

• Architecture: Utilizes a microprocessor-based design with onboard memory for firmware and user-defined control logic.

• Communication Interface: Connects via the Bailey Controlway or Slave Bus, allowing it to communicate with other modules like the Multi-Function Processor (MFP).

• Mounting: Occupies a single slot in the standard INFI 90 module mounting unit (MMU).

Product Advantages

The DFC 01 module offers several key benefits for users maintaining legacy control systems.

• High Performance Logic: It provides rapid execution of digital logic, making it suitable for high-speed interlocking and protective functions.

• Proven Reliability: The Bailey INFI 90 series is world-renowned for its "mission-critical" durability, often operating continuously for decades without failure.

• Seamless Integration: Designed to plug directly into existing Bailey cabinets, it requires no mechanical modification to the system infrastructure.

• Diagnostic Capabilities: The module includes onboard status indicators that allow technicians to quickly identify hardware faults or communication errors.

Important Considerations and Precautions

When handling or installing the DFC 01, specific safety and operational guidelines must be followed.

• Electrostatic Discharge (ESD): This module contains highly sensitive electronic components. Always wear a grounded ESD wrist strap when handling the board to prevent permanent damage.

• Legacy Support: As this is a legacy product, technical support is specialized. It is important to ensure that the firmware version on the module is compatible with your existing system configuration.

• Live Insertion: While many Bailey modules are "hot-swappable," it is highly recommended to follow the specific system manual guidelines before removing or inserting modules to avoid bus glitches or unexpected process trips.

• Storage Environment: If kept as a spare, the module should be stored in an anti-static bag in a temperature-controlled environment free from corrosive gases.

Product Applications

The DFC 01 is widely used in industries where process downtime is extremely costly and safety is paramount.

• Power Generation: Used in boiler control, burner management systems (BMS), and turbine control logic.

• Petrochemical Industry: Managing complex distillation processes and safety shutdown systems.

• Pulp and Paper: Controlling large-scale machinery and chemical recovery cycles.

• Water Treatment: Handling the automated logic for filtration and distribution systems on a large scale.
