Emerson KJ4001XI-NB1 DeltaV 1-Wide I/O Carrier Extender
The Emerson KJ4001XI-NB1 (also noted as KJ4001X1-NB1) is a 1-wide I/O carrier extender engineered for Emerson DeltaV M-Series distributed control systems. Functioning as a dual left-side LocalBus cable extender, it enables physical expansion across I/O carriers while maintaining local bus communication and delivering dual DC/DC converted 12 VDC local bus power up to 8 A.
Electrical Ratings and Bus Powering
The module supplies 12 VDC at 8 A (12.6 VDC nominal) across the local bus using internal dual DC/DC converters. It supports bussed field power ratings of 30 VDC at 6.5 A, permitting extended carrier layouts up to a maximum combined LocalBus length of 6.5 m without compromising signal integrity.
Environmental Tolerances and Hazardous Area Certifications
Designed for DIN rail mounting on T-type carriers, the compact unit measures 166 mm x 47 mm x 67 mm with an IP20 rated enclosure. It operates across ambient temperatures from -40 deg C to +70 deg C (5–95% non-condensing relative humidity) and holds ATEX, IECEx, and FM approvals for hazardous location deployments. The card is rated for 10 g shock resistance and ISA-S71.04-1985 Class G3 airborne contaminant protection.
