Overview Manuals Applications Monitoring Installation Certifications

Features:

  • Provides thirty-two high-side 24 VDC discrete outputs at 100 mA per channel.
  • Uses optical isolation from the system with a 1500 VDC factory test.
  • Enables termination-fault detection only with supported mass-connection hardware.
The current ordering configuration is KC3020X1-BA2, the DeltaV 32-channel high-side Plus discrete output card.

It gives process units a compact output interface for relays, indicators, solenoids, and other compatible 24 VDC loads.

Before commissioning, verify the B4 key, 3.2 A field-power budget, load current, simplex or redundant design, and the exact termination solution.

Availability is subject to Apter Power inventory and sourcing confirmation.
Verified resources for Emerson KC3020X1-BA2:Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Switches dense groups of low-current 24 VDC relays, indicators, solenoids, and interface circuits.
  • Serves packaged equipment, utilities, sequence control, and process-unit discrete output assignments.
  • Supports redundant high-density output assemblies when paired with the specified redundant termination hardware.
  • Reports card-integrity conditions through DeltaV hardware alerts for maintenance visibility.
  • Makes card and channel health information available through the DeltaV Diagnostics Explorer.
  • Adds termination-fault detection only when a supported mass-connection or Pepperl+Fuchs HiC arrangement is installed.
  • Uses the documented B4 rotary key to prevent connection to an incompatible terminal block.
  • Requires verification of both 12 VDC Local Bus demand and the 24 VDC field-power capacity before loading the card.
  • Allows online replacement only where the approved safe-area procedure permits it; hazardous locations require the applicable installation procedure.
  • Carries the II 3G Ex ec nC IIC Gc marking for the documented hazardous-area configuration.
  • Uses a conformally coated design that meets ISA-S71.04-1985 Class G3 contaminant requirements.
  • Must be installed under the conditions and terminal arrangements stated in the applicable Emerson approval instructions.
Description
KC3020X1-BA2 is the Emerson DeltaV 32-channel 24 VDC high-side Plus discrete output card for dense traditional-I/O field switching.

The card provides thirty-two 100 mA outputs, a 24 VDC ±10% output range, low off-state leakage, optical isolation from the system, and hardware-alert visibility through DeltaV diagnostics.

Termination-fault detection is available only with supported S-Series mass-connection solutions or Pepperl+Fuchs HiC barriers and boards. Confirm the B4 key, 3.2 A field-power capacity, load demand, and termination hardware before installation.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which terminations enable fault detection with KC3020X1-BA2?
Use a supported S-Series mass-connection solution or the specified Pepperl+Fuchs HiC barrier and termination-board arrangement.
Can KC3020X1-BA2 be configured for redundant service?
DeltaV supports redundant 32-channel high-side output assemblies when the proper redundant terminal hardware and system configuration are used.
What should be checked when a KC3020X1-BA2 channel does not energize its load?
Check bussed field power, channel demand, output wiring, the load circuit, terminal hardware, and DeltaV hardware alerts.
Why is the B4 key important when replacing KC3020X1-BA2?
It prevents an incompatible I/O card from being installed on the existing terminal block.
May KC3020X1-BA2 be serviced under power in a hazardous area?
Follow the approved hazardous-area maintenance procedure; do not assume energized exchange is permitted for the installed location.
What details should accompany a KC3020X1-BA2 sourcing request?
Provide the complete model, termination type, simplex or redundant arrangement, quantity, destination, and required approvals.
