Emerson KC3040X1-BB1 PLC5 24 VDC DI Signal Conditioner Card
A DeltaV signal-conditioning card for a legacy PLC5/1771 24 VDC discrete-input path.
Overview
Emerson KC3040X1-BB1 is a PLC5 24 VDC discrete-input signal conditioner card used at the interface between legacy PLC5/1771 field wiring and the documented DeltaV discrete-input architecture.
Emerson specifies that the card connects only to the KC3021X1-BA2 DI 32-channel 24 VDC Dry Contact Plus card. The complete suffix therefore belongs in every spare, receiving and installation record.
The card contains no user-serviceable parts and does not require calibration. Field power and system power restrictions in the applicable hazardous-area procedure remain part of every removal or insertion plan.
Specifications
Features
Legacy signal adaptation
Conditions the documented PLC5/1771 24 VDC input path for the specified DeltaV-side DI card.
Exact electrical boundary
The 10–30 VDC channel range differentiates this execution from other KC3040X1 conditioner variants.
Controlled hardware pairing
Emerson limits the published connection to KC3021X1-BA2, making associated-card identity part of the spare decision.
Industrial environmental rating
Published shock, vibration, humidity and G3 contaminant limits support controlled cabinet installation.
Applications
PLC5 migration interface
Retaining a legacy 24 VDC discrete-input field circuit while using the specified DeltaV DI architecture.
Controlled outage replacement
Replacing the same conditioner execution after the voltage, card pairing and terminal path are documented.
Hazardous-location maintenance
Service performed under the applicable Zone 2 / Division 2 removal and insertion procedure.
Lifecycle
Capture
Record {{MODEL}}, the associated KC3021X1-BA2 identity, field voltage, carrier position and terminal photographs.
Isolate
Remove the required field and system power before disconnecting the conditioner under the approved site procedure.
Verify
Confirm polarity, 10–30 VDC signal behavior, channel state reporting and stable operation after return to service.

FAQ
Can KC3040X1-BB1 be replaced by KC3040X1-BA1?
No automatic substitution should be made. KC3040X1-BB1 is documented for a 24 VDC DI path, while BA1 is a different 120 VAC / 125 VDC conditioner execution.
Which DeltaV card must be checked with KC3040X1-BB1?
Emerson specifies the KC3021X1-BA2 DI 32-channel 24 VDC Dry Contact Plus card for this conditioner.
What field evidence should accompany a KC3040X1-BB1 enquiry?
Provide both labels, the legacy swing-arm terminals, field-voltage measurements, carrier position, quantity and destination.
Does KC3040X1-BB1 require calibration after installation?
No. Emerson identifies no calibration requirement and states that the unit has no user-serviceable parts.
What proves KC3040X1-BB1 is ready after service?
Document correct power restoration, stable field voltage, expected channel-state transitions and matching identities for the conditioner and associated DI card.
