Product Details

Product Overview

The Emerson KJ4002X1-BF2 (Part No. 12P3866X012) provides vital physical flexibility for DeltaV Distributed Control Systems (DCS). This high-capacity bus extender cable bridges the gap between I/O carriers, allowing engineers to distribute 8-wide I/O modules across multiple rack levels or separate enclosures. It maintains the integrity of the 12.6 VDC LocalBus power and communication signals over a 4-foot distance. We supply this component as 100% Brand New, ensuring factory-spec signal conductivity and connector tension for long-term system stability.

Technical Specifications

The KJ4002X1-BF2 manages high-current power distribution and high-density data signals:

Engineering Advantages

• Optimized Cabinet Footprint: Standard DeltaV backplanes often limit horizontal expansion. This extender cable allows you to move I/O carriers to the next DIN rail or a separate cabinet section, maximizing every inch of available space.

• Maintains High Amperage: Unlike generic data cables, the KJ4002X1-BF2 handles up to 15 Amps of LocalBus power. It ensures that downstream I/O modules receive consistent voltage without dangerous heat buildup or voltage drops.

• Survives Harsh Environments: With a G3-rated coating and a wide temperature range, this cable resists corrosion and mechanical fatigue in chemical plants or offshore platforms where atmospheric contaminants are prevalent.

• Simplified Maintenance Access: By extending the bus, you can position I/O modules away from high-voltage components or crowded wiring ducts, providing technicians with clear access for diagnostics and hot-swapping.

FAQs

Q: Can I daisy-chain multiple KJ4002X1-BF2 cables to reach longer distances?

A: Emerson does not recommend daisy-chaining extender cables. Excessive length increases impedance and can cause voltage drops on the 12.6 VDC rail, potentially leading to intermittent I/O communication errors or module resets.

Q: Does this cable support both S-Series and M-Series DeltaV hardware?

A: Yes. The 44-pin LocalBus architecture remains consistent across both series, allowing this cable to extend connectivity for various 8-wide and 4-wide carrier configurations.

Q: Are the connectors locking type?

A: The 44-pin connectors feature secure friction-fit and mechanical alignment pins. For high-vibration environments (up to 0.5g), we recommend ensuring the cable is properly supported by cable ties to prevent strain on the carrier interface.

Q: What is the lead time for this specific part?

A: We typically ship the KJ4002X1-BF2 within 1-2 weeks. We utilize FEDEX or DHL for all international shipments to ensure tracked, door-to-door delivery.
