Procurement managers deploy this specialized ten-slot carrier housing to anchor and power critical co-processor boards, highway gateways, and advanced control processors. By maintaining a highly stable, low-impedance backplane power distribution system, the chassis prevents slot-to-slot voltage cross-talk and data synchronization delays. This heavy-duty hardware infrastructure secures real-time distributed data management across demanding, high-risk production centers including automated chemical processing lines, marine LNG containment vessels, and baseload steam power stations. The K2LCN-4 isolates sensitive communication logic links from external electrical spikes, keeping supervisory control console pipelines active and eliminating the threat of unpredicted total node blackouts.\u003c\/p\u003e\n\u003ch2\u003eBackplane Bus Engineering and Multi-Slot Architecture\u003c\/h2\u003e\n\u003cp\u003eThe K2LCN-4 utilizes a rigid, multi-layered motherboard backplane designed to distribute regulated dual-redundant DC power evenly to all ten hardware slots simultaneously. The electronic trace layout optimizes impedance matched parallel bus tracks, ensuring that high-speed token-passing data maintains crisp rise and fall times without reflecting signals at the slot junctions.\u003c\/p\u003e\n\u003cp\u003eTo support complex process nodes, the internal architecture integrates hardwired slot address routing lines that automatically assign physical identities to inserted processor modules based on their slot position. This localized hardware logic layout eliminates the need for software assignment steps, enabling rapid module hot-swapping and deterministic card boot sequences. Integrated ground planes blanket the entire rear profile of the board, forming an active Faraday shield that blocks severe electromagnetic field interference from surrounding cabinet relays.\u003c\/p\u003e\n\u003ch2\u003eChassis Dimensional Data and Load Constraints\u003c\/h2\u003e\n\u003ch3\u003eBackplane Proportions and Logistics\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003ctd\u003e\u003cstrong\u003eStructural Parameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eEngineering Certified Metric\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eManufacturer\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eHoneywell\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eModel Identifier\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eK2LCN-4 (51401551-400)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eCountry of Origin\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eUnited States\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eHarmonized System (HS) Code\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e85389091\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003ePhysical Weight\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e4.80 kg (10.58 lbs)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eShipping Dimensions\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e510 mm x 360 mm x 220 mm\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eElectrical and Environmental Limits\u003c\/h3\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr class=\"firstRow\"\u003e\n\u003ctd\u003e\u003cstrong\u003eOperational Attribute\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eCertified Performance Rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eEnclosure System Type\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eTen-Slot Local Control Network Co-Processor Chassis\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eDC Input Power Paths\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eDual-Redundant +5V DC, +12V DC, -12V DC Rails\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eBackplane Bus Structure\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eSynchronous Parallel Token-Passing Highway\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eWorking Temperature Range\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e0°C to +55°C (32°F to 131°F) Continuous\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eRelative Humidity Envelope\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003e5% to 95% RH Non-Condensing Operational\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cspan\u003eIngress Isolation Level\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cspan\u003eIP20 Open Frame Sub-Rack Mounting Format\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eRack Integration and Earth Grounding Protocol\u003c\/h2\u003e\n\u003cp\u003eMount the K2LCN-4 chassis firmly into a standard 19-inch industrial rack enclosure, using four heavy-duty pan-head fasteners through the reinforced front mounting ears.

The equipment travels protected within rigid, double-walled industrial exterior cartons cushioned by high-density, custom-molded shock-absorbing foam blocks, ensuring your critical network carrier hardware arrives clean, dry, and ready for immediate rack installation.\u003c\/p\u003e\n\u003ch2\u003eChassis Network Infrastructure FAQs\u003c\/h2\u003e\n\u003cp\u003eQ1: What specific system layout variation does the \"-400\" part suffix indicate for this K2LCN-4 module?\u003c\/p\u003e\n\u003cp\u003eA1: The -400 suffix represents the fourth-generation hardware revision of the ten-slot LCN backplane. This build incorporates upgraded high-temperature connector blocks and reinforced multi-layer grounding tracks, delivering superior signal isolation and longer operational runtimes compared to older -100 or -200 series chassis.\u003c\/p\u003e\n\u003cp\u003eQ2: Can technicians mix different generations of LCN co-processor and memory cards within this single chassis?\u003c\/p\u003e\n\u003cp\u003eA2: Yes. The K2LCN-4 backplane maintains full, backward-compatible parallel bus architectures. It allows legacy cards to operate right alongside newer revision modules in the same rack space, provided you align the card position addresses according to your primary Honeywell system loading rules.\u003c\/p\u003e\n\u003cp\u003eQ3: How does a grounding failure on the chassis frame manifest during live plant operations?\u003c\/p\u003e\n\u003cp\u003eA3: An ungrounded or poorly grounded chassis lets stray electrostatic charges build up on the backplane shield. This accumulation introduces high-frequency noise spikes into the data bus, showing up on operator stations as intermittent token drop errors or mysterious communication timeouts on adjacent slots.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":45518930837677,"sku":"K2LCN-4","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/honeywell-k2lcn-4-51401551-400-ten-slot-modules-j1211cw1a5v.jpg?v=1766982101","url":"https:\/\/www.maxwellplc.com\/products\/honeywell-k2lcn-4-51401551-400-ten-slot-lcn-chassis-rack","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
