Working Principle:
The KJ4002X1-BF1 extends the DeltaV local bus from the bottom connection point of a rack to another rack or device. The cable assembly carries the local bus communication signals, power, and control signals between the connected racks. This allows the DeltaV controller to communicate with I/O modules installed in remote racks as if they were locally connected, enabling distributed I/O architectures while maintaining high-speed communication performance. The -4 package provides 4 identical cables for multi-rack deployments.
Installation Requirements:
- Connect each cable assembly between the bottom extender port of the source rack and the corresponding input of the target rack
- Ensure connectors are properly aligned and fully seated before locking
- Route cables away from high-voltage power cables to minimize interference
- Use cable ties or cable trays to secure and organize cable runs
- Verify that the total cable length does not exceed DeltaV local bus specifications
- Follow DeltaV system wiring and grounding guidelines
- Label cables for easy identification during maintenance
Usage Precautions:
- Confirm that the cable assembly model matches the DeltaV system configuration
- Ensure only trained personnel install or maintain the cable assembly
- Do not exceed the maximum cable length specified for the DeltaV local bus
- Avoid bending cables beyond the minimum bend radius
- Regularly inspect cable connections for signs of wear or damage
- Follow proper electrostatic discharge (ESD) precautions when handling connectors
- Verify that connected racks are properly grounded
- Do not use damaged cables; replace immediately if any damage is detected
- The 4-pack is suitable for projects requiring multiple extender cables; verify quantity needs before ordering
