Stock New Original Honeywell K4LCN-16 51403519-160 LCN Memory Processor Module

The Honeywell K4LCN-16 51403519-160 is a high-capacity LCN Memory Processor Module designed for the TDC 3000/TPS distributed control system. It serves as a critical node on the Local Control Network (LCN), executing control logic, managing system memory, and handling high-speed network communications. Featuring 16 megawords of onboard memory and a Motorola 68040 processor, it addresses the memory limitations of older K4LCN-8 variants, preventing data loss during high alarm throughput conditions.

    FAQs

    Q1: What is the difference between K4LCN-16 and K4LCN-8?
    A: The K4LCN-16 features 16 MW of memory, while the K4LCN-8 has only 8 MB. The K4LCN-8 can experience memory overflow during high alarm bursts, causing LCN node resets and loss of history archives. The K4LCN-16 eliminates this issue for high-volume nodes.

    Q2: What is the primary function of the K4LCN-16?
    A: It executes control logic, manages system configuration and historical parameters, processes real-time data, handles alarms, and manages LCN network communications with other DCS stations.

    Q3: Is the K4LCN-16 hot-swappable?
    A: Yes, the K4LCN-16 supports online replacement (hot-swap) in compatible TDC 3000 configurations.

    Q4: What are the key field installation requirements?
    A: Always run two separate 75Ω LCN coax cables to both A and B connectors for redundant communication paths. Never install a single coax cable, as this creates a single point of failure. Also perform annual ECC memory diagnostic tests to detect hidden single-bit errors.

    Q5: What is the alternate designation for this module?
    A: The new Honeywell K4LCN-16 is also called K4SDR.
