Honeywell 51305381-500 Connecting Cables

Configured for low-latency serial data transmission in Honeywell DCS architectures, the HONEYWELL 51305381-500 (51305381 Data Transfer Cable) provides direct physical/electrical execution.

Suffix Breakdown & Model Matrix

• 51305381: Base catalog designation for the serial data interconnect assembly.
• -500: Specific length variant code designating a 2.5 m cable length with 6-pin male connector headers.

Hardware Specifications

Process Control and Channel Isolation Properties

• 4-20 mA HART Loop Protocol Compatibility: Shielded multi-conductor layout isolates low-voltage serial data streams from nearby 4-20 mA current loop interference.
• Galvanic Noise Suppression: Braid shielding isolates data transfer lines against high-frequency electromagnetic noise and transient earth potential variances.
• Low-Impedance Signal Paths: Engineered with tinned-copper conductors to maintain serial signal waveform integrity across the entire 2.5 m run.

Frequently Asked Questions

Q: What connector pinout footprint is utilized on the 51305381-500 cable assembly?

A: The cable features standard 6-pin male serial connector terminations on both ends for direct mating into compatible DCS communication ports.

Q: Does the 51305381-500 require external auxiliary power?

A: No, the assembly is a passive physical cable and consumes no operating electrical power.

Q: Can the cable be connected or disconnected while the communication port is actively transmitting data?

A: Hot-swapping serial communication cables during active transmission may cause data packet corruption; pause serial polling or de-energize the port prior to disconnection.

Field Installation Guidelines

1. Inspect the 6-pin male connectors for pin alignment and verify port receptacles are free of contamination before insertion.
2. Maintain a minimum bend radius of 40 mm along the 2.5 m cable route to avoid strain on internal copper conductors.
3. Keep the cable physically isolated from AC power distribution lines by running serial wiring in separate grounded raceways with a minimum 300 mm separation.
4. Tighten connector thumbscrews securely to establish reliable signal contact and housing shield continuity.
