Technical Specifications

Engineering Advantages

• Redundant Configuration Support: The KJ4006X1-BB1 facilitates redundant signal routing. By providing a single termination point that interfaces with dual I/O cards, it ensures that your process remains online even if a single analog input card fails.

• Mechanical Alignment Security: The integrated rotary keying system prevents human error during installation. This system ensures the terminal block only seats with the correct compatible I/O card type, protecting the control system from electrical mismatches and potential hardware damage.

• High-Integrity Signal Paths: Designed for sensitive 4-20mA and HART® signals, the terminal block utilizes low-resistance contact points to minimize signal attenuation. This ensures the DeltaV system receives precise data for critical control calculations.

• Rugged Industrial Build: The block withstands extreme thermal cycling from –40°C to +70°C and features high shock and vibration resistance. This durability makes it ideal for remote instrument enclosures (RIEs) located near heavy rotating machinery or in harsh outdoor environments.

• Simplified Field Wiring: The layout prioritizes clear labeling and accessible screw terminals, which reduces the time required for loop commissioning and simplifies future maintenance tasks or field modifications.

FAQs

• Can I use the KJ4006X1-BB1 with non-redundant I/O cards?

  While the block is physically compatible with the S-series carrier, it is specifically wired for redundant applications. Using it in a non-redundant setup may leave half of the interface unused. We recommend matching the terminal block type exactly to your I/O card's redundancy configuration.

• Does this terminal block require external power?

  No. The KJ4006X1-BB1 is a passive termination component. It routes signals and power provided by the I/O card and the carrier backplane to the field instruments.

• How does the rotary keying system work?

  Each DeltaV S-series I/O card has a specific key position. You must set the rotary keys on the KJ4006X1-BB1 to match the card's requirements before it will snap into place on the carrier, ensuring a foolproof "lock-and-key" installation.
