The Emerson KJ4001X1-BE1 (12P0818X092) is an 8-wide I/O interface carrier with an integrated shield bar for the DeltaV M-series system. It provides a rugged, G3-certified mounting platform for 8 I/O modules, supporting LocalBus power distribution and hot-swappable expansion in hazardous industrial environments.
The Emerson KJ4001X1-BE1 (also identified by part numbers 12P0818X092 and VE4050S2K1C0) serves as an 8-wide I/O interface carrier for the DeltaV M-series automation system. This component provides the physical and electrical foundation for mounting up to eight I/O cards and their corresponding terminal blocks. Because it features an integrated shield bar, the carrier effectively drains electromagnetic interference away from sensitive signal wiring, ensuring superior data integrity in high-noise industrial environments.
This carrier simplifies system expansion by allowing modules to snap directly onto a standard T-type DIN rail. It distributes 12.6 VDC LocalBus power to all seated I/O cards through an internal backplane, which eliminates the need for individual power wiring to each module. Furthermore, the KJ4001X1-BE1 facilitates online expansion, enabling technicians to add new 8-wide carriers to an active system without interrupting existing processes. The carrier also manages the distribution of bussed field power (up to 30 VDC), providing a streamlined energy path for field sensors and actuators.
