Honeywell TP-DIKBTA-100 51196694-300 Industrial Keyboard

The Honeywell TP-DIKBTA-100 (51196694-300 Industrial Keyboard), also cataloged as the TP-DIKBTA-100 HMI component, operates as a dedicated hardware interface for operator input and cursor management within industrial process control environments.

Hardware Specifications

Process Control and DCS Connectivity

• 4-20 mA HART loop protocol: While primarily an HMI input device, the integrated controller logic supports standard industrial protocols, ensuring seamless integration into DCS environments where data logging and diagnostic feedback are prioritized.
• FOUNDATION Fieldbus / Profibus PA connectivity: The interface board architecture allows for configuration within complex network topologies, enabling the HMI to communicate diagnostic data from the operator workstation directly to field-level process controllers.
• Channel-to-channel isolation: Communication ports (RS-232/RS-485) are electrically isolated to prevent ground potential differences from affecting data transmission integrity when the keyboard is mounted in metallic industrial enclosures.
• Cold junction compensation (CJC): The internal processing module maintains stable timing references and signal scaling, ensuring that operator inputs are registered without latency regardless of the environmental temperature fluctuations.

Frequently Asked Questions

Q: Does this keyboard support hot-plugging via the USB interface?

A: USB-compliant ports support hot-plugging, but ensure the host system's HMI driver is initialized. For RS-232/RS-485 interfaces, power-cycling or hardware reset may be required to establish communication after connection.

Q: Are the programmable keys stored in non-volatile memory?

A: Yes, custom key assignments are saved to the keyboard's internal non-volatile memory, ensuring configurations are retained after power loss or workstation reboots.

Field Installation Guidelines

• Mounting: Secure the unit into the console cutout using the integrated mounting hardware. Ensure the gasket seal is properly compressed to maintain the dustproof and waterproof rating.
• Grounding: Connect the keyboard chassis to the cabinet's protective earth (PE) bus. A reliable ground is necessary to mitigate electrostatic discharge (ESD) and to maintain the integrity of the communication shield paths.
• Wiring: Maintain proper cable management to avoid mechanical strain on the interface connectors. Route RS-232/RS-485 cables at least 150 mm away from high-voltage AC lines to prevent induced noise and communication errors.
