Yokogawa AIP831-101 CENTUM VP Eight-Loop Operation Keyboard

Product Overview

The Yokogawa AIP831-101 serves as a specialized Human Interface Station (HIS) peripheral for the CENTUM VP ecosystem. It enables operators to manage eight process loops simultaneously, drastically improving response times in high-pressure control room environments. This flat-profile keyboard integrates touch-sensitive sensors that trigger the "Instrument Faceplate Highlight" function upon contact. We supply this unit as 100% Brand New and Original, ensuring full compatibility with your desktop-type HIS workstations.

Technical Specifications

• PC Interface: Dual USB A-type connectors

• Interface Standards: USB 2.0 (Keyboard) / USB 1.1 (Audio)

• Chassis Color: Black (Munsell No. N1.5)

• Operating Temperature: 5 to 40°C (Normal operation)

• Ambient Humidity: 20 to 80% RH (Non-condensing)

• Software Requirement: Requires LHS1140 Eight-loop Simultaneous Operation Package

Engineering Advantages

The AIP831-101 optimizes the operator's interface with the DCS through several technical innovations:

• Tactile Efficiency: The dedicated 8-loop key layout eliminates the need to toggle through multiple software menus. Operators adjust setpoints and outputs across eight different controllers with physical keys, reducing the risk of manual entry errors during critical process upsets.

• Instant Visual Feedback: Contact with the touch-sensitive keys instantly highlights the corresponding instrument faceplate on the HIS monitor. This hardware-to-software synchronization allows the operator to verify the target loop without shifting focus between the screen and the desk.

• Integrated Alarm Management: The included USB speaker provides localized audible alerts. This ensures that the operator hears critical alarms directly at their station, even in noisy control rooms, without relying on central console speakers.

• Plug-and-Play Installation: The module draws power directly from the USB bus. This eliminates the need for external power supplies and simplifies cable management in cramped desktop environments.

FAQs

• Which CENTUM VP software versions support the AIP831-101? You must use CENTUM VP R5.03 or later. Additionally, the system must run the LHS1100 or LHM1101 Standard Operation and Monitoring function. Note that this keyboard does not support LHS1120 or LHS1130 packages.

• Does this keyboard require a separate power cable? No. The AIP831-101 operates entirely on USB bus power. It utilizes two USB Type-A connectors to manage both the keyboard input signals and the sound function.

• Can I connect multiple AIP831 units to a single HIS? Yokogawa specifications restrict usage to one AIP831 per Desktop Type HIS workstation to ensure stable driver communication and power distribution.

• Is the "Instrument Faceplate Highlight" feature automatic? Yes. Once you touch the sensors on the control keys, the software package (LHS1140) automatically identifies the loop and brings the corresponding faceplate to the foreground on the HIS display.
