Honeywell 51308097-200 Touchscreen Interface Cable Assembly

The Honeywell 51308097-200, also cataloged as the 51308097 Touchscreen Interface Cable, serves as the primary 51308097 Touchscreen Interface Cable utilized to execute physical data connection between a Touchscreen Controller Board and industrial operator interface systems across Honeywell Universal Station and Experion PKS platforms.

Hardware Specifications

Process Control Integration & Cable Shielding

Operating as a critical interface within human-machine interface (HMI) nodes, the 51308097-200 integrates physical shielding to prevent signal degradation:

• 4-20 mA HART Loop Coexistence: High-rejection foil-shielded pairs inside the cable prevent high-frequency serial signals from radiating and introducing noise into nearby low-voltage analog 4-20 mA HART loops running in the same cable ducting.
• Channel-to-Channel Isolation Support: The grounded metallic connector shell establishes a continuous shield path from the touchscreen frame directly to the cabinet ground plane, isolating the core control electronics from external electromagnetic interference (EMI) or surge currents.
• Accurate Signal Reference: Low conductor loop resistance ensures that voltage levels for resistive and capacitive touch coordinates remain precise, preventing cursor drift or missed inputs during system control actions.

Frequently Asked Questions

Q: Can this touchscreen interface cable be routed through high-voltage electrical conduits?

A: No. While the insulation is rated for 300 V, routing the 51308097-200 near AC power lines can induce signal noise that will disrupt touchscreen coordinate transmission. Always separate the interface cable from high-voltage wiring by at least 300 mm.

Q: Is it possible to cut and splice this cable to fit custom console spacing?

A: No. Splicing the 4-pair shielded cable can introduce characteristic impedance mismatches and breach the continuous shield envelope, leading to signal loss or touch controller communication errors. Use the factory-terminated length.

Field Installation Guidelines

• Secure Connector Housing: Fully insert the sub-D plugs into the touchscreen controller board and terminal receptacles. Tighten the securing thumbscrews on the metallic connector hoods to prevent physical disconnection due to operator panel vibration.
• Observe Minimum Bend Radius: Ensure the cable routing path maintains a minimum bend radius of at least eight times the outer cable diameter. Avoid tight crimps or pinching points near the back of the HMI bezel.
• Shield Grounding Path Continuity: Verify that the metallic outer connector shell makes solid physical contact with the grounded chassis of the terminal cabinet, preserving a continuous drain path to the common instrumentation earth.
• Physical Protection: Run the cable through protective flexible conduit or standard wire tracks within the operator console to safeguard against abrasion and mechanical strain during hinge movements.
