Description
Product Overview
The Emerson KJ3007X1-EA1 is a dedicated terminal-block assembly for PROFIBUS DP connectivity in DeltaV control systems. It provides the physical wiring interface associated with a compatible PROFIBUS DP card, allowing the fieldbus network to be terminated at the control-system cabinet. Its role is distinct from that of the communication card itself: the terminal block provides the connection point, while the card performs the network communication functions.
For maintenance engineers, the key issue is correct matching between the terminal block, the installed communication card, and the field wiring. PROFIBUS DP installations are sensitive to network topology, cable termination, shielding, and grounding. A replacement terminal block should therefore be checked for the correct part number and connector arrangement before existing wiring is transferred. A physical fit alone is not enough to establish compatibility.
When purchasing the KJ3007X1-EA1, verify the identification label and inspect the terminal connections for damaged screws, corrosion, heat discoloration, or cracked insulation. Confirm whether the existing installation uses the original terminal-block arrangement and whether any network-specific termination components are fitted. Published listings identify a 5 VDC, 100 mA rating, but the applicable Emerson documentation should govern electrical checks and installation.
Product Introduction
The Emerson KJ3007X1-EA1 is a DeltaV PROFIBUS DP terminal block intended to simplify field wiring for compatible PROFIBUS communication hardware. It is a connection and termination component, not a standalone fieldbus controller.
For replacement work, confirm the communication-card model, terminal-block revision, wiring layout, and network termination arrangement. Listings indicate that the part has been discontinued by the manufacturer, so legacy-system buyers should pay particular attention to the actual condition, provenance, and test evidence of available stock.

Frequently Asked Questions
Q1: What is the Emerson KJ3007X1-EA1 used for?
It provides wiring terminations for a compatible DeltaV PROFIBUS DP communication card. It is a terminal-block accessory, not the PROFIBUS master or controller itself.
Q2: What voltage does the use?
Component listings specify 5 VDC at up to 100 mA. Confirm these values against the applicable Emerson documentation and installed configuration before electrical work.
Q3: Is the a PROFIBUS communication card?
No. It is the terminal block associated with the wiring interface for a PROFIBUS DP card. The communication card performs the fieldbus interface functions.
Q4: Can it be replaced with another DeltaV terminal block?
Not without verification. Different DeltaV terminal blocks serve different communication or I/O functions. Check the exact part number, mating card, connector layout, and wiring requirements.
Q5: Is the discontinued?
Component-reseller listings report it as discontinued by the manufacturer. Confirm lifecycle status and approved replacement options with Emerson for the specific installed system.
Q6: What should be checked when buying used stock?
Inspect the label and terminals, verify the exact model, and request photographs of the actual part. If possible, obtain evidence of continuity checks, physical inspection, and confirmation that the terminal block matches the intended PROFIBUS card.
Q7: Does replacing the terminal block require checking the PROFIBUS network?
Yes. After replacement, verify wiring polarity, shielding, grounding, cable termination, and network diagnostics according to the site procedure. A terminal-block replacement can introduce connection faults even when the communication card itself is functioning normally.
