Honeywell TP-DIKBTA-100 IKB Keyboard with Trackball

The Honeywell TP-DIKBTA-100, also cataloged as the 51196694-300 HMI/MMI input device, operates as a dedicated hardware component for operator interface control within DCS platform environments. This keyboard module integrates a physical trackball to execute cursor positioning and data entry tasks, facilitating direct operator interaction with the host process control system.

Hardware Specifications

4-20 mA HART Loop Protocol Integration

While this HMI component functions primarily as a human-interface peripheral, it is designed for seamless operation within control rooms utilizing the 4-20 mA HART loop protocol architecture. The integration of high-precision trackball pointing ensures that operators can manage HART-enabled device parameters, such as tag configuration and diagnostic monitoring, without excessive latency. This hardware interface maintains signal integrity for operator-initiated commands, ensuring that user inputs to the DCS station translate accurately to field-level device configuration changes across the instrument network.

Frequently Asked Questions

Q: Is this keyboard unit compatible with standard USB or PS/2 port connections?

A: The TP-DIKBTA-100 is designed for specific integration with Honeywell IKB console interfaces. Verify the port type (USB or legacy PS/2) on your existing operator station console before installation to ensure electrical and protocol compatibility.

Q: Can the integrated trackball be cleaned or disassembled for maintenance?

A: The trackball assembly is designed for field-level cleaning of the ball and optical sensor housing. Do not use chemical solvents that may degrade the polycarbonate surfaces or the optical tracking lens.

Field Installation Guidelines

• Physical Mounting: Secure the keyboard to the operator console surface using the provided mounting points to prevent movement during high-frequency usage.
• Cable Management: Ensure the interface cable is routed through designated cable management pathways. Avoid tight radius bends or pinching of the cable against sharp metallic surfaces to prevent internal wire breakage.
• Environment Protection: Ensure the operator station is located in a controlled environment to minimize the ingress of conductive dust or high-humidity air that may affect the keyboard’s internal contact membrane.
• Initial Commissioning: Upon installation, verify the HID (Human Interface Device) drivers are recognized by the operator station OS. Test trackball tracking sensitivity and button response cycles to confirm proper peripheral handshaking.
