Product Overview
The Honeywell 51309204-175 is a critical conformally coated Power Adapter, specifically engineered to support Low Level Analog Input Multiplexer (LLMux), Serial Device Interface (SDI), and Serial Interface (SI) subsystems within Honeywell’s TPS (TotalPlant Solution) and TDC 3000 distributed control systems (DCS). As a key intermediary component, it serves as a power distribution and signal conditioning hub, facilitating reliable communication and power delivery between Input/Output Processors (IOPs) and associated Field Termination Assemblies (FTAs) in harsh industrial environments.
Designed to replace non-conformally coated legacy models (e.g., 51304467-100), the 51309204-175 addresses corrosion-related failures common in aggressive settings—such as oil & gas refineries, chemical plants, and power generation facilities—by incorporating a protective conformal coating (per IPC-CC-830 standards). This coating shields the printed circuit board (PCB) from moisture, dust, and chemical contaminants, extending the component’s lifespan in harsh conditions.
The Power Adapter enables flexible integration with both local and remote FTAs: it connects directly to LLMux, SDI, or SI IOPs via shielded/unshielded cables (up to 50 meters) and supports FTA connections up to 305 meters using specialized external cables. It is CE-compliant when paired with compatible CE-rated cabling (e.g., MU-KFTSxx) and card files, ensuring adherence to European Union EMC and safety directives for industrial equipment.
Key Features
Conformal Coating for Harsh Environment Durability
IPC-CC-830 Compliant Coating: The PCB is coated with a moisture, dust, and chemical-resistant conformal layer, enabling operation in harsh environments classified as G2 (moderate) to G3 (harsh) per ANSI/ISA-S71.04-1985. It withstands corrosive gases (e.g., H₂S, SO₂) and humidity ranges of 10–90% (non-condensing), eliminating premature failures caused by corrosion.
Broad Temperature Tolerance: Operates in temperatures ranging from -20°C to +60°C (operating) and -40°C to +80°C (storage), making it suitable for both indoor control cabinets and semi-outdoor enclosures (when paired with IP54-rated housing).
Versatile Compatibility with Multiple Subsystems
Multi-Subsystem Support: Seamlessly integrates with three critical subsystems:
LLMux: Powers LLMux FTAs (e.g., MU-TAMR03 for RTDs, MU-TAMT03 for thermocouples) to enable low-level analog signal multiplexing.
SDI: Supports SDI FTAs (e.g., MU-TSDT02 for Toledo Weigh Cells, MU-TSDM02 for Manual/Auto Stations) for serial communication with peripheral devices.
SI: Works with SI FTAs (e.g., MU-TSIM12 for Modbus, MU-TSIA12 for Allen-Bradley devices) to facilitate asynchronous serial data transfer.
Backward Compatibility: Directly replaces non-conformally coated legacy Power Adapters (e.g., 51304467-100) without modifying existing wiring, cabinet layouts, or IOP configurations, simplifying retrofits.
Reliable Power Distribution & Signal Integrity
Dual Power Input Redundancy: Accepts redundant 24 Vdc power inputs (derived from HPM Power Systems) to ensure uninterrupted operation. Internal diodes prevent cross-feeding between power sources, eliminating short-circuit risks if one source fails.
Signal Conditioning: Incorporates filtering circuitry to reduce electromagnetic interference (EMI) and radio-frequency interference (RFI) from industrial equipment (e.g., motors, transformers). This preserves signal integrity for low-level analog signals (e.g., thermocouple millivolt signals) and serial data streams (e.g., EIA-232/422/485).
Flexible Cabling & Installation
Long-Distance Connectivity: Supports both internal cabinet cabling (e.g., 51304465-xxx, up to 3 meters) and external cabinet cabling (e.g., MU-KLXxxx, up to 305 meters) for remote FTA placement. This flexibility enables optimal subsystem design in large industrial sites.
A-Size Form Factor: Matches the dimensions of standard A-size FTAs (152.4 mm × 120.7 mm), allowing easy mounting on vertical or horizontal FTA Mounting Channels (e.g., MU-TMCN01, MU-TMCW01) without additional brackets.
CE Compliance & Safety Certifications
CE Marking: Complies with EU EMC Directive (89/336/EEC) and Low Voltage Directive (2014/35/EU) when used with CE-rated IOP to FTA cables (e.g., MU-KFTSxx) and card files (e.g., MU-HPFI03).
Hazardous Location Compatibility: Certified for use in Class I, Division 2 (Groups A–D) and Zone 2 (Group IIC) hazardous areas when installed in a certified IP54 enclosure, making it suitable for explosive environments common in oil & gas operations.
