Product Introduction

The Emerson KJ1501X1-BC1 is a DeltaV M-Series system power supply designed to accept either 12 VDC or 24 VDC input and generate regulated DC power for the DeltaV system electronics. Its main output is +12 VDC, with additional +5.1 VDC and +3.4 VDC outputs for system circuitry.

The module is installed in either slot of the DeltaV 2-wide power/controller carrier. It incorporates internal input fusing, output overvoltage protection, hold-up capability, and alarm relay contacts for monitoring the auxiliary supply outputs.

Installation & Configuration Guide

Stage 1 — Pre-Installation

  1. Confirm the complete part number KJ1501X1-BC1 from the existing module label.
  2. Record the assembly number and revision shown on the physical nameplate.
  3. Verify whether the installed system uses a 12 VDC or 24 VDC primary input.
  4. Confirm that the replacement is intended for the same DeltaV M-Series power/controller carrier.
  5. Check the carrier slot and adjacent modules for physical damage or contamination.
  6. Review the existing power-distribution documentation before disconnecting the supply.
  7. Establish a controlled shutdown and follow the site’s electrical safety and lockout/tagout procedure.

Stage 2 — Removal

  1. Remove input power from the power supply before disconnecting the input connector.
  2. Verify that hazardous or stored electrical energy has been addressed according to site procedures.
  3. Disconnect the external DC input connection.
  4. Disconnect or isolate the alarm-contact wiring if fitted.
  5. Remove the KJ1501X1-BC1 from its DeltaV carrier slot.
  6. Inspect the carrier connector before installing the replacement.

Safety warning: Emerson’s DeltaV documentation specifies that input power must be removed before connecting or disconnecting the power-supply input connection.

Stage 3 — Installation

  1. Verify the replacement module’s model and revision against the removed unit.
  2. Confirm that the carrier is the correct DeltaV M-Series 2-wide power/controller carrier.
  3. Insert the KJ1501X1-BC1 into the appropriate carrier slot.
  4. Secure the module according to the carrier installation procedure.
  5. Reconnect the DC input wiring with correct polarity.
  6. Reconnect the alarm relay wiring where applicable.
  7. Verify that the input supply matches the system’s documented 12 VDC or 24 VDC configuration.

Stage 4 — Power-On and Testing

  1. Energize the DC supply under controlled conditions.
  2. Check the status indication.
  3. Verify the +12 VDC system output.
  4. Check the auxiliary +5.1 VDC and +3.4 VDC supplies where test access is provided.
  5. Confirm that the power-supply alarm circuit reports a normal condition.
  6. Check DeltaV system controllers and associated modules for power-related diagnostic alarms.
  7. Confirm stable operation under the normal system load.
  8. Record the installed module revision and power-supply configuration for maintenance records.

 

FAQ

What is the Emerson ?

The is a DeltaV M-Series System Power Supply (Dual DC/DC). It accepts either 12 VDC or 24 VDC input and provides regulated DC outputs used by DeltaV system electronics.

What are the main output ratings?

With a 12 VDC input, the documented main output is +12 VDC at 13.0 A. With a 24 VDC input, the documented output is +12 VDC at 4.5 A. The supply also provides +5.1 VDC at 2.0 A and +3.4 VDC at 2.0 A, with a combined auxiliary-output limit of 10.2 W.

Is a DeltaV controller?

No. It is a system power supply, not a DeltaV controller or I/O module. Its function is to provide the required regulated DC power within the DeltaV M-Series hardware architecture.

What carrier does use?

The DeltaV hardware reference specifies installation in either slot of the 2-wide power/controller carrier.

Is the same as VE5008?

Some secondary-market listings associate VE5008 and assembly numbers such as 12P2186X022 / 12P2186X032 with . Because assembly-number and revision relationships can vary by production version, the safest replacement method is to match the complete nameplate and Emerson documentation rather than relying on a cross-reference alone.

Does support both 12 VDC and 24 VDC input?

Yes. The DeltaV M-Series specification identifies both 12 VDC and 24 VDC input configurations for , with different +12 VDC output ratings depending on the input voltage.

Does the module provide alarm contacts?

Yes. The documented external alarm interface uses normally open relay contacts. The contact rating is 30 VDC at 2.0 A or 250 VAC at 2.0 A. The relays are associated with the health of the 3.3 VDC and 5 VDC auxiliary outputs.

What should I verify before purchasing a replacement?

Verify the complete designation, assembly number, revision, carrier type, input voltage, and physical connector configuration. This is particularly important because secondary-market listings show more than one assembly number associated with this model.

Is suitable for a new DeltaV installation?

It is primarily a replacement component for existing DeltaV M-Series installations. For a new system, the applicable Emerson DeltaV hardware generation and currently supported power architecture should be evaluated rather than designing around a legacy spare part.
