Emerson KJ4001X1-BE1 DeltaV M-series 8-wide I/O carrier with integrated EMI shield bar, supports hot-swappable standard I/O modules for process DCS.

Product Overview

• Part No: KJ4001X1-BE1, Alternate PN:12P0818X072
• Brand: EMERSON DeltaV

• Category: 8-Wide Shielded I/O Carrier KJ4001X1-BE1 is an 8-slot passive I/O carrier for DeltaV M-series standard I/O system. It accommodates up to eight hot-swappable analog and discrete I/O modules. Equipped with an integrated EMI shield bar bonded to chassis ground, it effectively suppresses electromagnetic interference for stable signal transmission. This carrier provides LocalBus communication and field power distribution between backplane and I/O modules. It supports HART-enabled I/O cards and simplifies cabinet wiring layout. It serves as essential rack infrastructure spare for petrochemical, oil & gas and power plant DeltaV automation systems.
