    Honeywell K4LCN-16 (51403519-160) LCN Node Memory Processor Card for TDC3000
    Manufacturer: Honeywell Process Solutions
    Model: K4LCN-16, Part No. 51403519-160
    Series: TDC3000 / Experion PKS Legacy LCN Control System
    Type: High-performance LCN bus node memory processor board
    Function: Core computing & memory unit for LCN network nodes (NIM, Global Station, History Module, HM); Motorola 68040 CPU + 16MB fixed onboard memory; native LCN 5MHz bus communication; real-time data exchange between operator stations, controllers, history servers; system clock synchronization, fault diagnosis, program storage & execution for legacy DCS nodes
    1. Overview
    K4LCN-16 is the top-tier upgraded LCN node processor card for Honeywell classic TDC3000 DCS, replacing older K2LCN / K4LCN-4 / K4LCN-8 low-memory versions. It adopts Motorola 68040 32-bit industrial processor with fixed 16MB onboard memory (non-expandable), fully compatible with all LCN bus equipment including Network Interface Modules (NIM), Global Operator Stations, History Collectors, and Application Processors. The card integrates a dedicated LCN bus transceiver, supporting standard 5Mbps LCN synchronous communication, provides millisecond-level clock synchronization for all LCN nodes, and undertakes heavy-duty tasks such as real-time process data caching, control logic storage, trend history calculation, and operator graphic rendering. Compared with small-memory K4LCN variants, K4LCN-16 supports large-scale plant-wide DCS nodes with heavy load, especially systems with large process graphics, massive historical data storage, and multiple UCN controller connections. It is a VME rack plug-in board, supports hot-swap maintenance, widely used in petrochemical, power, oil & gas old TDC3000 system renovation and stable operation.

    3. Key Features
    • 16MB Large Fixed Memory Meet high-load node requirements; Global Station needs at least 8MB, NIM only consumes ≤4MB, reserve capacity for large graphics & historical data
    • 68040 High-Speed 32-bit Processor Higher computing performance than old 68020 K2LCN boards, reduce LCN bus communication delay under heavy data traffic
    • Integrated Native LCN Transceiver No external communication daughter card, direct access to LCN control network for inter-node data transmission
    • System-wide Clock Synchronization Standard 5MHz LCN clock frame generation, ensure all controllers & stations run on unified time base
    • Full Node Compatibility Applicable to all LCN node types, single card replaces K4LCN-4 / K4LCN-8 low-memory models for unified spare parts management
    • VME Hot-Swap Support Replace board online without full rack power shutdown, minimize production downtime
    • Legacy System Upgrade Preferred Card Solve memory overflow, slow graphic refresh, historical data loss issues of old small-memory LCN processors
    4. Applications
    • Refinery & petrochemical plant TDC3000 Global Operator Station core processing board
    • Thermal power plant boiler/turbine unit NIM network interface node memory processor
    • Oil & gas pipeline compressor station LCN history data recording module main board
    • Old TDC3000 system renovation upgrade, replace aging K2LCN / K4LCN-4 / K4LCN-8 boards
