Emerson KJ3224X1-BK1 DeltaV S-Series Thermocouple / mV Input Card
An S-Series low-level input card for thermocouple and millivolt signals, with C1 terminal-block keying and published environmental limits.
Technical Summary
PRODUCT CONTEXTKJ3224X1-BK1 is the Emerson DeltaV S-Series Thermocouple/mV Input Card. It is intended for low-level temperature and millivolt measurement paths and uses 12 V DC local-bus power at the manufacturer-published 210 mA load.
The terminal block uses rotary key position C1. Emerson also requires a completed I/O loop assessment for energy-limited nodes, so the card, terminal block, sensor type and compensation wiring must be reviewed as one measurement path.

Features
FUNCTIONAL DISTINCTIONSLow-level signal path
Supports the dedicated thermocouple and millivolt measurement role within DeltaV S-Series I/O.
C1 physical keying
The rotary terminal-block key creates a visible compatibility boundary at installation.
Energy-limited loop control
Manufacturer instructions explicitly call for loop assessment on energy-limited nodes.
Service discipline
The module is not intended for disassembly and contains no user-serviceable parts.
Compatibility
SELECTION BOUNDARIESSensor and compensation
Match thermocouple type, polarity, extension wire and any cold-junction arrangement recorded for the installed loop.
Terminal pairing
Use the terminal block keyed C1 and retain its conductor map with the module identity.
Approval context
Review the site hazardous-area design and applicable DeltaV S-Series installation instructions before replacement.
Replacement
SERVICE WORKFLOWCapture
Record KJ3224X1-BK1, the C1 terminal block, configured sensor type, range, compensation method and channel assignment.
Exchange
Remove field and system power under the approved procedure and keep thermocouple polarity and shielding unchanged.
Validate
Compare each active input with a traceable reference and confirm diagnostics, engineering units and alarm behavior.
FAQ
CUSTOMER DECISION SUPPORTWhich signals belong on KJ3224X1-BK1?
The manufacturer identifies it as a thermocouple and millivolt input card, so the configured sensor type and low-level wiring must match.
What terminal key is assigned to KJ3224X1-BK1?
The Emerson instruction sheet specifies rotary terminal-block key position C1.
Can KJ3224X1-BK1 be inserted with system power on?
No. Emerson states that the unit cannot be removed or inserted with system power energized.
What field evidence should accompany a KJ3224X1-BK1 request?
Send the complete label, terminal-block identity, thermocouple types, channel ranges, polarity record and loop drawings.
How should KJ3224X1-BK1 be accepted after service?
Use a suitable reference source to prove each configured channel and document stable readings, diagnostics and alarm points.
