MU-KDPR10 Honeywell Power Distribution Cable

Configured for power distribution and interconnecting system modules in Honeywell DCS environments, the Honeywell 51201397-010 (MU-KDPR10 Power Distribution Cable) provides direct physical/electrical execution.

Hardware Specifications

Channel Isolation & 4-20 mA Loop Interfacing

The multi-core shielded cable structure isolates internal 24 VDC auxiliary power lines from high-frequency radiated interference. This grounding and shielding design suppresses electromagnetic coupling onto nearby analog signal buses, maintaining low-noise conditions required for accurate transmission of 4-20 mA HART loop protocol process variables.

Frequently Asked Questions

Q: Does the cable shield require grounding at both ends of the harness?

A: To prevent ground loops while maintaining EMI protection, the overall cable shield should be bonded to the main termination cabinet earthing bar at a single grounding point per system installation standards.

Q: Can the MU-KDPR10 cable be connected or disconnected while system power is active?

A: Power feeds supplying the cable harness should be isolated before mating or unmating connectors to prevent pin degradation from electric arc discharge.

Q: How does the cable insulation tolerate industrial cabinet environments?

A: The industrial-grade outer jacket is rated for operation between -20 deg C and +80 deg C with a 300 V insulation rating, providing physical protection against ambient heat and electrical stress.

Field Installation Guidelines

• Verify that power supply sources are de-energized prior to connecting or routing the power cable assembly.
• Maintain minimum bend radius limits along the cable length to prevent conductor fatigue and shield separation.
• Keep power distribution cabling physically segregated from low-level analog input wiring and high-voltage AC trunks.
• Ensure pre-terminated connectors are fully seated and locked into the module headers to maintain continuous low-resistance contact.
• Verify single-point shield earthing at the designated cabinet grounding bar to eliminate circulating shield currents.
