Honeywell FS-PDC-MB24-2 Power Distribution Cable

Configured for 24 VDC auxiliary power distribution in Honeywell Safety Manager racks, the Honeywell FS-PDC-MB24-2 (FS-PDC-MB24-2 Power Distribution Cable) provides direct physical/electrical execution across high-integrity backplanes.

Hardware Specifications

4-20 mA HART Loop Protocol and Channel-to-Channel Isolation

The FS-PDC-MB24-2 power cable uses continuous metallic shielding and twisted-pair power cores to suppress common-mode noise on the main 24 VDC bus lines. The shielded design prevents high-frequency power switching transients from coupling into nearby low-level measurement loops. This maintains channel-to-channel isolation boundaries across analog module chassis, preserving signal accuracy for field instruments utilizing the 4-20 mA HART loop protocol.

Frequently Asked Questions

Q: What is the physical length and primary application of the FS-PDC-MB24-2 cable?

A: The cable measures 2.0 meters (6.56 ft) in length and is designed to route 24 VDC power between main distribution bus rails and secondary chassis slots in Safety Manager cabinets.

Q: Can the FS-PDC-MB24-2 cable be flexed during installation inside tight wire ducts?

A: Yes, the cable utilizes multi-strand high-flex copper conductors designed for tight-radius routing within industrial control enclosures.

Q: Is hot-unplugging permitted on the FS-PDC-MB24-2 cable assembly during live system operation?

A: No, the 24 VDC power feed should be isolated before disconnecting the cable to avoid contact arcing and backplane supply interruptions.

Field Installation Guidelines

• Verify that the main 24 VDC power bus is de-energized prior to connecting or disconnecting the cable plugs.
• Secure the connector retention clips fully into the mating backplane sockets to withstand panel vibration.
• Route the flexible cable within dedicated power wire channels, separated from low-voltage analog signal leads.
• Fasten cable drain wires securely to the main cabinet protective earth bar to maintain effective shield coverage.
