Emerson DeltaV KJ3201X1-BA1 — DI, 8-Channel, 24 VDC, Isolated
The KJ3201X1-BA1 is a digital input (DI) card from the Emerson DeltaV distributed control system (DCS), part of the DeltaV Series 2 I/O family. It provides 8 isolated 24 VDC digital input
channels, carrying field signals from switches, contacts and discrete sensors into
the DeltaV control system. The KJ3201X1 model identifies the card, and the -BA1 suffix denotes its specific hardware revision. Manufactured by Emerson (Emerson Process Management). Widely used as a genuine spare for
existing DeltaV installations.
- Emerson DeltaV Series 2 digital input card
- 8 isolated 24 VDC DI channels
- Model KJ3201X1, revision -BA1
- For the DeltaV distributed control system
- Process-industry I/O spare
Key Features & Functions
Digital Input Channels
Provides 8 channels of 24 VDC discrete input, capturing on/off signals from field devices such as switches, contacts, limit switches and proximity sensors.
Channel Isolation
Channels are electrically isolated, improving noise immunity and protecting the control system from field transients.
DeltaV Series 2 Integration
Designed to slot into DeltaV Series 2 I/O carriers, integrating directly with the DeltaV control system.
Process-Industry Reliability
Built for continuous operation in process plants — chemical, oil & gas, power, pharmaceutical and similar environments.

Source note: The KJ3201X1 DeltaV card is confirmed as an 8-channel,
24 VDC isolated digital input module in Emerson’s DeltaV Series 2 I/O range. Verify
current availability, the exact -BA1 revision, carrier compatibility and any
engineering limits against the official Emerson datasheet before purchase — revision
suffixes can indicate different compatible hardware.
Typical Application Scenarios
- Process Plant Control: capturing discrete field signals in chemical, oil & gas, power and pharmaceutical plants.
- Discrete Signal Monitoring: reading switch, contact and sensor states into the DeltaV control system.
- Safety & Interlock Inputs: feeding discrete status signals to the control strategy.
- Legacy System Maintenance: keeping existing DeltaV installations running with genuine I/O spares.
- Spare Part Replacement: replacing failed I/O cards in the field.
Frequently Asked Questions
What is the Emerson DeltaV KJ3201X1-BA1?
It is an 8-channel, 24 VDC isolated digital input card for Emerson’s DeltaV distributed control system, part of the DeltaV Series 2 I/O range.
Is it a B&R or Bently Nevada part?
No — this is an Emerson DeltaV part, a third manufacturer brand in this list. DeltaV is a process-industry distributed control system, distinct from B&R automation hardware and Bently Nevada machinery-protection equipment.
What does the -BA1 suffix mean?
It denotes the specific hardware revision of the card. Confirm the exact revision and its compatibility with your carrier and system version in the official Emerson documentation.
How does it work with the DeltaV system?
The card slots into a DeltaV Series 2 I/O carrier and communicates with the DeltaV controller, providing discrete input data to the control strategy.
Where can I find the official datasheet?
Official technical documentation is available from Emerson and authorized DeltaV distributors. Verify all specifications there before purchase.
