It provides the necessary signal integrity and electrical isolation required to maintain system safety certifications (ATEX, IECEx, FM) when extending the LocalBus across multi-enclosure configurations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocalBus Expansion:\u003c\/strong\u003e The unit serves as a critical bridge, facilitating the extension of the DeltaV LocalBus beyond a single I\/O carrier. This allows for modular system scalability and physical layout optimization within complex control cabinets.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Power Distribution:\u003c\/strong\u003e The module facilitates the distribution of 12 VDC LocalBus power and 30 VDC bussed field power across carrier interfaces. This architecture streamlines wiring requirements while ensuring stable voltage levels for downstream I\/O modules and field devices.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnvironmental Adaptability:\u003c\/strong\u003e Engineered to meet ISA-S71.04-1985 Class G3 standards for airborne contaminants, the extender ensures long-term operational stability in corrosive or harsh industrial atmospheres.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can this extender be removed or inserted while the system is under power?\u003c\/p\u003e\n\u003cp\u003eA: No. The KJ4001XI-NB1 must not be inserted or removed with system power energized. Ensure the LocalBus and field power are de-energized before connecting or disconnecting the extender cables to prevent electrical arcing or damage to the backplane.\u003c\/p\u003e\n\u003cp\u003eQ: Is there a limit to the total length of the LocalBus extension?\u003c\/p\u003e\n\u003cp\u003eA: Yes. The combined length of all I\/O carriers and LocalBus Extender cables must not exceed 6.5 meters. Exceeding this limit can result in signal attenuation and communication timing errors between the controller and I\/O interface.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Snap the extender onto a standard T-type DIN rail. Ensure the unit is flush with the adjacent I\/O carrier and that the bus connectors are fully engaged to provide continuous electrical contact.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring:\u003c\/strong\u003e Interconnecting cables between enclosures must be routed within protective conduit to maintain safety and EMC compliance.

This provides the necessary low-impedance path for EMI suppression and keeps the extender circuitry at equipotential with the rest of the DCS node.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bachmann","offers":[{"title":"Default Title","offer_id":45163129077875,"sku":"KJ4001XI-NB1","price":410.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/screenshot_2026-07-06_15-13-56_eb21fff2-f738-485e-b2ab-1ccc32e07833.png?v=1783325472","url":"https:\/\/www.dcssupplier.com\/products\/emerson-kj4001xi-nb1-i-o-carrier-extender","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
