3BSE018173R1 SM811K01 ABB Bailey Output Module

Product  Description：

• • An ABB Bailey output module typically consists of a printed circuit board housed in a protective casing, designed to be inserted into a module mounting unit (rack) within the DCS cabinet. Each module is equipped with multiple output channels, allowing it to control several devices simultaneously. These modules are engineered for high reliability and robust performance in demanding industrial environments, ensuring precise and consistent control of critical processes. They receive processed data and control commands from a Multi-Function Processor (MFP) or other control modules via a high-speed backplane bus.

     

    Key Functions

     

    • Signal Conversion: Converting digital control signals from the DCS controller into analog (e.g., 4-20 mA, 0-10V) or digital (on/off) signals suitable for field devices.

    • Actuation: Driving final control elements like control valves, motor starters, solenoids, annunciators (buzzers, lamps), and relays.

    • Isolation: Providing electrical isolation between the sensitive control electronics and the field wiring, protecting the DCS from electrical noise and surges.

    • Diagnostic Capabilities: Often include LED indicators for channel status and internal diagnostics to aid in troubleshooting.

    • Protection: Incorporating features like short-circuit protection and ground fault detection to ensure system integrity and safety.

     

    Product Parameters (Typical Examples)

     

    Parameters vary significantly by module type (e.g., analog output, digital output) and specific model. Here are common ranges:

    Digital Output Modules (e.g., IMDSO02, NDSO02):

    • Number of Channels: Typically 2, 8, or 16 channels.

    • Output Type: Open collector transistor, solid-state relay (SSR), or electromechanical relay (EMR).

    • Output Voltage: Commonly 24 VDC, 48 VDC, 125 VDC, or 120 VAC.

    • Output Current: Ranges from milliamps to several amps per channel (e.g., 3 Amps per channel for IMDSO02; 2A per channel at 240VAC for NDSO02).

    • Isolation: Typically 500 VAC or higher between channels and field side.

    • Protection: Fused protection, short circuit protection.

    Analog Output Modules (e.g., IMASO01, IMASO11):

    • Number of Channels: Typically 8 or 14 channels.

    • Output Range: 0-20 mA, 4-20 mA, 0-10 V, 1-5 V.

    • Accuracy: Typically ±0.1% of Full Scale Range (FSR).

    • Load Resistance: Minimum load resistance specified (e.g., Min 250 ohms for current output).

    • Isolation: Often present between channels and common ground.

    General Parameters (Applicable to most ABB Bailey Output Modules):

    • Power Supply: Typically receives power from the system's termination unit/module, often 5 VDC, 15 VDC, 24 VDC.

    • Operating Temperature: Wide industrial range, typically -40°C to +70°C (-40°F to +158°F).

    • Storage Temperature: -40°C to +85°C.

    • Humidity: 5% to 95% non-condensing.

    • Mounting: Designed for standard module mounting units (MMUs) within DCS cabinets.

    • Compatibility: Specifically designed for integration with ABB Bailey INFI 90, Network 90, Harmony, or Symphony DCS platforms.

     

    Product Advantages

     

    • Robust and Reliable: Built for continuous operation in harsh industrial environments, ensuring high availability of control systems.

    • Seamless Integration: Designed to integrate flawlessly within ABB Bailey DCS architectures, simplifying system design and commissioning.

    • Precise Control: Provides accurate and stable output signals for precise control of field devices, crucial for maintaining process quality and efficiency.

    • Diagnostic Capabilities: Features like LED indicators and fault detection enhance troubleshooting and reduce downtime.

    • Field-Proven Technology: Benefits from decades of operational experience in critical applications across various industries.

    • Modularity: Allows for flexible system expansion and easy replacement of individual modules.

     

    Precautions

     

    • ESD (Electrostatic Discharge) Sensitivity: Handle modules with care, employing proper ESD precautions (e.g., grounding straps) during installation and maintenance.

    • Compatibility: Ensure the specific output module is compatible with your existing ABB Bailey DCS controller, termination units, and system software version.

    • Wiring Standards: Adhere strictly to ABB's wiring guidelines and local electrical codes to ensure proper operation, prevent electrical hazards, and minimize noise interference.

    • Power Requirements: Verify that the system's power supply meets the module's specified voltage and current requirements, especially for modules driving higher current loads.

    • Configuration: Proper software configuration within the DCS is essential for the correct functioning of the output channels. Incorrect settings can lead to improper control actions or system instability.

    • Hot-Swapping: While some ABB modules may support hot-swapping, always consult the specific module's manual to confirm if it can be inserted or removed without powering down the system. Incorrect hot-swapping can cause damage.

    • Environmental Limits: Operate the module only within its specified temperature, humidity, and vibration limits to ensure longevity and reliable performance.

     

    Product Applications

     

    ABB Bailey output modules are widely used across various industries that rely on Distributed Control Systems for automated process control.

    • Power Generation: Controlling steam turbine governors, generator excitation systems, boiler controls (e.g., fuel flow, air dampers), and balance-of-plant equipment in thermal, hydro, and nuclear power plants.

    • Oil and Gas: Actuating control valves, pump motors, and compressor trip systems in refineries, pipelines, and offshore platforms.

    • Chemical and Petrochemical: Regulating flow rates, temperatures, and pressures in chemical reactors, distillation columns, and other processing units.

    • Pulp and Paper: Controlling machine speeds, chemical dosing, and process flows in paper mills.

    • Water and Wastewater Treatment: Operating pumps, valves, and chemical feed systems for water purification and distribution.

    • Metals and Mining: Controlling furnace operations, material handling systems, and rolling mills.
