Honeywell 51305830-400 AC Power Splitter Cable

The Honeywell 51305830-400, also cataloged as the 51305830-400 AC Power Splitter Cable, operates as a dedicated hardware component for AC power distribution and dual-load branching within Honeywell DCS rack enclosures.

Hardware Specifications

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

• Channel-to-Channel Isolation: Provides individual heavy-duty molded strain reliefs at branching junctions to isolate parallel power runs, preventing mechanical fatigue and phase shorts.
• 4-20 mA HART Loop Protocol: Isolates AC power distribution conductors within grounded metal conduits to prevent high-voltage AC inductive coupling into adjacent 4-20 mA HART analog communication loops.
• Cold Junction Compensation (CJC): Maintains stable power transmission to power supply modules feeding remote termination assemblies and cold junction compensation terminal blocks.

Frequently Asked Questions

Q: What current and voltage ratings apply to the plugs on the 51305830-400 cable?

A: The input male plug is rated at 15 A 125 V, while the dual output female connectors are each rated for up to 13 A 250 V.

Q: How does this power cable assist with DCS cabinet wiring layout?

A: It functions as an AC splitter assembly, enabling a single mains AC power feed to distribute power directly to two separate system power supplies or rack components.

Q: Are there special conductor shielding requirements when routing this cable near signal lines?

A: To preserve signal integrity, AC power splitters must be routed through separate high-voltage wiring channels away from sensitive analog and communication buses.

Field Installation Guidelines

• Input Voltage Verification: Confirm that the cabinet utility AC supply matches the voltage and current ratings of the connected hardware loads before plugging in the assembly.
• Physical Wire Separation: Route AC power cable assemblies through designated high-voltage cabinet raceways, maintaining a minimum physical separation from low-voltage instrument wiring.
• Connector Engagement: Ensure both 13 A 250 V female connectors are fully seated into their receiving equipment inlets to prevent high-resistance terminal connections.
• Strain Relief Inspection: Verify that the main 15 A 125 V plug and branch connections are secured without sharp bends to avoid cable jacket tension or conductor stress.
