Emerson DeltaV KJ1501X1-BB1 DC/DC System Power Supply Module

Overview

The Emerson KJ1501X1-BB1 is a DeltaV™ M-series Enhanced DC/DC System Power Supply (catalogued as VE5002). It converts 12 VDC or 24 VDC bulk power into the regulated voltages required by DeltaV controllers and I/O interfaces. The plug-and-play module mounts directly into any power-supply slot of a DeltaV power/controller carrier, eliminating external cabling between the supply, controller, and I/O carriers.

FAQ

Q: Can I power this supply from a 24 VDC plant bulk source?
A: Yes. The KJ1501X1-BB1 accepts either 12 VDC or 24 VDC input and automatically regulates the output bus.

Q: Is this module hot-swappable?
A: No. Power must be de-energized before removing or inserting the supply to prevent arcing and bus damage.

Q: What is the difference between BB1 and BA1?
A: The BA1 is a dual DC power supply with similar form factor; the BB1 is a passthrough 12/12 VDC supply. Verify your carrier power budget before selecting.

Installation Guidelines

1. Mount the Power/Controller carrier on a T-type DIN rail.
2. Connect bulk 12 VDC or 24 VDC to the carrier field terminals.
3. Align the KJ1501X1-BB1 with the carrier slot and press firmly until seated.
4. Do not remove or insert while system power is energized.

Selection Tips

• Use KJ1501X1-BB1 when your bulk power is already 12 VDC or 24 VDC and you need a passthrough supply for M-series controllers.
• For dual-redundant power architectures, install two supplies on a redundant-capable carrier.
• Confirm carrier width (2-wide vs. 4-wide) before ordering.
