Product Description

The KJ1501X1-BB1 (12P0545X082) is a compact local bus power supply module used within the Emerson Electric DeltaV™ M-series distributed control system (DCS). It delivers regulated power to I/O subsystems via the backplane, ensuring stable logic voltage and uninterrupted communication across the carrier.

Designed for high-density installations, its 19 mm slim form factor allows efficient mounting in space-constrained control cabinets. As a plug-and-play component for DeltaV horizontal carriers, the module includes integrated overvoltage protection and diagnostic LEDs for real-time monitoring of the local power rail. It is engineered to meet stringent industrial requirements for high availability and electromagnetic compatibility (EMC).

Frequently Asked Questions

What is the difference between KJ1501X1-BB1 and redundant power options?
This module supports simplex (non-redundant) local bus power. For redundant configurations, a compatible redundant carrier and a matched pair of power supply modules are required.

Can this module be hot-swapped?
Yes. The DeltaV system architecture supports hot replacement of the KJ1501X1-BB1 without disrupting other active I/O nodes, provided overall backplane power requirements are properly managed.

Does this module provide field power?
No. It supplies local bus logic power only. Field device power must be provided separately according to system design.
