Description
Product Description
Overview
The KJ4001X1-CJ1 by Emerson is a shielded, high-performance LocalBus expansion cable designed for DeltaV™ S-series DCS systems. It connects the Right-Hand Expansion Port of one I/O carrier to the Left-Hand Expansion Port of another, enabling reliable data and power transfer across multiple I/O carriers. Ideal for bridging gaps on DIN rails or extending connections across cabinet rows.
Key Features
-
High-Speed Data Transfer: Maintains S-series LocalBus communication with minimal signal loss.
-
Shielded Design: EMI and RFI protection ensures robust operation in electrically noisy environments.
-
Redundant Communication Paths: Supports both primary and secondary data channels for uninterrupted operation.
-
Power Delivery: Transfers 12 VDC LocalBus power to downstream I/O modules.
-
Secure Connectors: High-density locking connectors prevent misalignment and vibration-induced disconnection.

FAQ
Q: Can this cable be used with DeltaV Series 2 I/O carriers?
A: No, the KJ4001X1-CJ1 is compatible only with S-series hardware.
Q: What is the maximum recommended LocalBus length with this extension?
A: Users should calculate total LocalBus length to avoid voltage drop or timing issues.
Q: Does this cable carry both data and power?
A: Yes, it provides 12 VDC LocalBus power along with data.
Q: Can I insert or remove the cable while the system is powered?
A: No, always de-energize the system before insertion or removal.
