Honeywell 51195096-100​ Distributed Control System (DCS) Communication Interface Card

Product Name and Core Positioning

Core Functions and Technical Features

1. Multi-Protocol Communication Support
• Communicates with host computers (operator stations, historical data modules) to transfer real-time process data, alarm information, and control commands.
• Compatible with 1 Mbps data rate, upgradable to 10 Mbps via expansion modules.
• Connects TDC 3000 controllers (e.g., HPM High-Performance Processors) to intelligent field devices (transmitters, actuators) with 5 Mbps high-speed data transmission.
• Supports redundant dual-ring topology with automatic primary/backup link switching and fault recovery time < 50 ms.
• UCN Network Adaptation:
• LCN Network Expansion:
2. Hardware Design and Reliability
• Operating temperature: 0°C ~ +40°C (non-condensing), storage temperature: -20°C ~ +60°C.
• EMC compliance with EN 61000-6-2/3, resistant to vibration (5-500 Hz, 2g) and shock (15g, 11 ms).
• Tri-color LED indicators (green - operational, yellow - communication, red - fault) provide real-time status feedback.
• Built-in self-diagnosis identifies faults like communication link interruptions or voltage anomalies, generating error codes.
• Hot-Swappable Capability: Enables online module replacement without system shutdown, enhancing maintenance convenience.
• Real-Time Diagnostics:
• Industrial-Grade Protection:
3. System Integration Capability
• BNC connectors: 2 (primary/backup UCN links), supporting coaxial cables or fiber optic conversion.
• DB-25 interface: 1 (for LCN or third-party system expansion).
• Physical Interfaces:
• Power Requirements: Powered by TDC 3000 chassis backplane with 24 VDC ±5%, typical power consumption ≤5 W.

Key Design Features

1. Redundant Communication Architecture
• Adopts dual-ring redundant network design, automatically switching to the backup link in case of a single-link failure, ensuring communication interruption < 100 ms—ideal for continuous control in high-risk sectors like petrochemicals.
2. Plug-and-Play Integration
• Requires no additional configuration software. When inserted into a TDC 3000 5-slot/10-slot chassis (e.g., 51400669-100 backplane), the system automatically identifies the module and assigns addresses, reducing engineering debug costs.
3. Long Lifecycle Support
• As part of the TDC 3000 legacy product line, Honeywell still provides 10 years of spare parts support and supplies refurbished units through third-party channels (e.g., DCS Center) to ensure prolonged operation of legacy systems.
