Description
Emerson KJ3001X1-CA1 | DeltaV 32-Channel DI Module
Product Introduction
When troubleshooting a DeltaV discrete input point, the distinction between a field-wiring fault and a failed input card matters. The Emerson KJ3001X1-CA1 is a 32-channel dry-contact discrete input module designed to receive 24 VDC field signals and make their status available to the DeltaV control system.
This module is not a generic 32-point PLC input card. It uses DeltaV-specific LocalBus and field-power connections, and its terminal block must be correctly keyed for the installed I/O card. The OEM instruction sheet identifies terminal block key position B3 and specifies a 24 VDC, 5 mA-per-channel field circuit rating.
For replacement procurement, verify the full KJ3001X1-CA1 model, associated ordering number, terminal-block compatibility, and actual system configuration. A physically similar DeltaV input card may have a different signal type or wiring requirement.

Global Sourcing & Live-Test SOP
For a used or surplus KJ3001X1-CA1, verify both the card’s physical condition and its ability to register input states correctly. A power-up alone does not demonstrate that all 32 channels function.
1. Inbound Verification
- Photograph the complete nameplate and all visible labels.
- Confirm the exact model KJ3001X1-CA1.
- Record the serial number, hardware revision, and full ordering number.
- Inspect the card body, edge contacts, connectors, and terminal interface.
- Check for corrosion, contamination, bent contacts, or signs of unauthorized repair.
- Verify that the terminal-block key position is compatible with the card.
- Compare the offered unit against the existing DeltaV bill of materials.
- Request traceability records and OEM documentation where available.
2. Controlled Power-Up
- Use a compatible DeltaV carrier or approved test setup.
- Confirm LocalBus and field-power requirements before energizing.
- Verify that the applicable 12 VDC LocalBus and 24 VDC field-power ratings are respected.
- Observe startup indicators and diagnostic status.
- Monitor for abnormal current draw, unexpected resets, or excessive heating.
- Do not apply field power until wiring and terminal assignments have been verified.
3. Channel-Level Functional Test
A meaningful test should exercise the input channels—not just confirm that the module is recognized.
- Use an approved test fixture or compatible dry-contact simulator.
- Exercise all 32 input channels where the test setup permits.
- Verify that open and closed contact states are correctly recognized.
- Check channel status through compatible DeltaV diagnostics or engineering tools.
- Record any intermittent, stuck, or unresponsive points.
- Verify the channel mapping against the intended terminal-block wiring.
- Document any channels that could not be tested.
4. Extended Test and Diagnostic Review
For units advertised as tested, perform an extended powered test using compatible hardware.
Monitor:
- Module recognition and diagnostic status
- Input-state consistency
- Unexpected channel changes
- LocalBus stability
- Field-power behavior
- Unexpected resets or abnormal heating
Record the test duration, equipment used, channel coverage, and observed results. Do not claim a 24-hour burn-in or full-channel test unless it was actually completed and documented.
5. Final Preparation and Shipment
- Record the complete model, ordering number, serial number, and revision.
- Photograph the card and its connectors.
- Preserve any included OEM documentation.
- Use ESD-safe handling and protective packaging.
- Protect contacts from impact and contamination.
- State the actual condition: used, refurbished, or unused surplus.
- Clearly identify seller warranty terms separately from any verified OEM warranty.
Field Engineer’s Pitfall Guide
❗ Do not confuse the DI card with its terminal block
The is the 32-channel discrete input module. The terminal block is a separate installation component, and the OEM documentation specifies key position B3. Confirm the correct terminal-block configuration before installing the card.
❗ Field power must be removed before card removal or insertion
The OEM instruction sheet allows conditional removal or insertion with system power energized, but field power supplied to the device—at the field terminal or through the carrier—must be removed first. The document also limits energized removal or insertion to one unit at a time and specifies additional hazardous-area conditions. Follow the applicable DeltaV and site procedures; do not interpret conditional hot-swap permission as unrestricted live maintenance.
❗ Do not substitute another DeltaV input card based on channel count alone
A 32-channel card may use a different input type, field-power arrangement, or terminal-block key. Confirm the exact model, signal type, and wiring requirements. The is specified for 24 VDC dry-contact inputs.
Intent-Driven FAQ
What is the Emerson ?
The is an Emerson DeltaV 32-channel discrete input module designed for 24 VDC dry-contact signals.
How many input channels does the have?
It provides 32 discrete input channels. For a replacement test, verify individual channel-state recognition rather than relying only on module-level diagnostics.
What power does the require?
The OEM instruction sheet specifies 12 VDC LocalBus power at 75 mA, 24 VDC bussed field power at 150 mA, and a 24 VDC / 5 mA-per-channel field circuit rating.
Can the be hot-swapped?
Only under the conditions specified by Emerson. Field power must be removed before connecting or removing the device, and energized removal or insertion is subject to additional system and hazardous-area restrictions.
Does the require calibration?
The OEM instruction sheet states that calibration is not required. Functional channel testing and system diagnostics are still appropriate when qualifying a replacement.
Is the obsolete?
Radwell lists the as discontinued by the manufacturer. It is therefore commonly encountered through legacy and surplus sourcing channels. Confirm current lifecycle status and replacement guidance with Emerson.
What should I verify before buying a replacement?
Confirm the exact model and ordering number, terminal-block key position, 32-channel dry-contact input type, hardware revision, physical condition, and seller’s test documentation. For production use, verify the module against the installed DeltaV configuration and approved maintenance procedure.
Bottom Line for Buyers
The is a legacy DeltaV 32-channel, 24 VDC dry-contact discrete input module. Its OEM specifications include 12 VDC LocalBus power at 75 mA, 24 VDC bussed field power at 150 mA, and a 24 VDC / 5 mA-per-channel field circuit rating.
For procurement, match the complete model and ordering number, verify the B3 terminal-block key, and request channel-level test evidence when the unit is sold as tested. Conditional hot-swap capability should never be treated as permission to remove the card with field power present.
