Honeywell 51308058-100 Keyboard Interface Cable Assembly

Configured for signal transmission in TDC 3000 Distributed Control System (DCS) operator stations, the Honeywell 51308058-100 (51308058-100 Keyboard Interface Cable Assembly) provides direct physical and electrical execution of keyboard-to-console data communication.

Hardware Specifications

DCS Process Control and Connectivity

• Signal Integrity and EMI/RFI Shielding: The 51308058-100 utilizes industrial-grade electromagnetic interference (EMI) and radio frequency interference (RFI) shielding to maintain signal integrity during operator data entry. In DCS environments, high-frequency noise can introduce latency or character corruption in console communication loops.
• Isolation and Noise Suppression: This assembly integrates isolation principles for internal data lines, ensuring that the proprietary connector interface maintains a stable connection between the operator keyboard and the console electronics. The design minimizes signal degradation over the 2–3 m cable span, preventing common-mode noise propagation that could trigger diagnostic faults within the operator station interface.

Frequently Asked Questions

Q: Is this cable assembly compatible with non-Honeywell keyboard interfaces?

A: No. The 51308058-100 features a Honeywell proprietary console connector interface. It is strictly designed for use with TDC 3000 operator stations and cannot be adapted for standard USB or PS/2 interfaces without custom hardware conversion.

Q: How should the cable be routed to maintain EMI/RFI shielding effectiveness?

A: The cable should be routed through dedicated conduit or cable trays, physically separated from high-voltage power lines and large electromagnetic sources (such as variable frequency drives or heavy motors) to avoid inductive interference.

Field Installation Guidelines

• Mounting: Ensure the proprietary connectors at both ends are fully seated and the locking mechanisms are engaged. Avoid over-tightening or applying excessive torque to the connector housing, as this can lead to pin deformation and intermittent connection issues.
• Grounding: The cable shield is integrated into the connector termination to provide a continuous path for EMI drainage. Ensure the operator station console chassis is properly bonded to the system common earth to maintain the efficacy of the cable shielding.
• Wiring: Maintain strict physical separation from AC distribution lines. In environments with high density of electrical noise, utilize grounded metal conduit to provide an additional layer of electromagnetic protection for the cable run.
