Honeywell CC-KREBR5 DO Relay Extension Cable

Configured for relay output expansion within Honeywell control system architectures, the Honeywell CC-KREBR5 (CC-KREBR5 DO Relay Extension Cable) provides a dedicated interconnection path between a DO Relay IOTA and a downstream DO Relay Extension IOTA. The cable assembly supports short-distance relay signal extension, maintains physical continuity between termination assemblies, and is designed for installation within Honeywell Series C and Series 8 cabinet environments.

Hardware Specifications

Channel Isolation and Relay Signal Interconnection

The CC-KREBR5 functions as a passive relay extension interface within Honeywell control system infrastructures. The cable assembly provides a dedicated electrical connection path between relay termination assemblies while preserving relay signal continuity. In configurations utilizing distributed relay outputs, proper interconnection practices assist in maintaining channel separation and minimizing unintended coupling between adjacent wiring paths. The assembly serves as a physical extension medium and does not perform signal conditioning, protocol conversion, or output processing.

Frequently Asked Questions

Q: Does the CC-KREBR5 require a power supply connection?
A: No. The cable is a passive interconnection assembly intended to transfer relay signals between compatible IOTA assemblies.

Q: What equipment does the CC-KREBR5 connect?
A: The cable is designed to connect a DO Relay IOTA to a downstream DO Relay Extension IOTA within compatible Honeywell control system installations.

Q: Does the cable provide electrical isolation?
A: The supplied documentation specifies an isolation voltage rating of 1000 VDC for the associated installation environment. No active isolation circuitry is identified within the cable assembly itself.

Field Installation Guidelines

• Verify compatibility between the installed DO Relay IOTA and the corresponding DO Relay Extension IOTA before connection.

• Route the cable within designated cabinet wiring paths to prevent excessive mechanical stress.

• Avoid sharp bends, excessive twisting, or compression of the cable assembly.

• Ensure connector latching mechanisms are fully engaged after installation.

• Maintain separation between relay wiring and high-current power conductors where practical.

• Inspect connector housings for physical damage before energizing the system.

• Confirm cable routing does not obstruct module removal or maintenance activities.

• Verify continuity of all relay extension circuits during commissioning procedures.
