Emerson DeltaV
KJ3224X1-BK1
The KJ3224X1-BK1 brings low-level thermocouple and millivolt signals into the DeltaV S-series I/O architecture. Eight channels support temperature and low-voltage measurement while keyed termination and card diagnostics protect the installed signal path.

01
|
Signal Conversion | Low-level thermocouple and millivolt signals are converted into process values for control, indication, alarming and history. |
|
02
|
Channel Configuration | Sensor type, engineering units, range, filtering, burnout direction and alarm limits are assigned for each channel. |
|
03
|
Compensation Path | Thermocouple accuracy depends on the selected terminal assembly and cold-junction compensation path. These parts form one measurement chain. |
|
04
|
Diagnostics | Card, channel and wiring conditions support maintenance decisions without changing the configured signal identity. |
|
05
|
Installation Control | Terminal-block keying, field wiring, power state and the complete BK1 product code must be confirmed before replacement. |

◎ PROCESS VALUE |
| ◆ | KJ3224X1-BK1 | S-series thermocouple/mV input card and the exact replacement target. |
| ◆ | TERMINAL ASSEMBLY | Provides field landing and cold-junction compensation; keying and sensor service must agree with the card. |
| ◆ | KJ3225X1-BK1 | RTD/resistance input card. It serves a different sensor and wiring method. |
| ◆ | KJ3222X1-BK1 | 4–20 mA HART input card. It is intended for current loops rather than thermocouples. |

| RETURN CARE | Contact us within seven days if a concern appears after receipt. | Keep the item in its original condition and state the reason. Resolution follows receipt and inspection. | Return-related shipping costs are paid by the buyer. |
| 01 | KJ3224X1-BK1: What must be matched before ordering? | Confirm the complete BK1 product code, hardware revision, carrier position, terminal assembly, channel configuration and connector condition. |
| 02 | KJ3224X1-BK1: Can an RTD card replace KJ3224X1-BK1? | No. RTD/resistance inputs use different excitation, measurement and wiring methods. Sensor type and termination must remain consistent. |
| 03 | KJ3224X1-BK1: Why does the terminal assembly matter? | It completes field landing, card keying and the thermocouple compensation path. A physically similar terminal assembly may not provide the required function. |
| 04 | KJ3224X1-BK1: Can KJ3224X1-BK1 be removed with power energized? | The card instructions require the applicable field and system power to be removed before connection or removal. Follow the approved site procedure. |
| 05 | KJ3224X1-BK1: What should accompany a quotation request? | Provide the full product code, revision, quantity, destination, required condition and clear photographs of all labels and connectors. |
