The Yokogawa AIP827-1 is a specialized USB Operation Keyboard designed for use with the CENTUM CS and CENTUM VP Distributed Control Systems (DCS). It serves as a dedicated human-machine interface (HMI) component, providing operators with efficient, tactile control over industrial processes from a Human Interface Station (HIS).

Product Details

Product Type: USB Operation Keyboard for Human Interface Station (HIS).
Design: A ruggedized, flat-panel keyboard featuring a dust-proof and drip-proof construction, optimized for control room environments.
Interface: Connects via a standard USB A-type connector.
Audio Support: Includes a built-in speaker and electronic buzzers to provide audible feedback for process alarms and system messages.
Software Compatibility: Compatible with Yokogawa software revision R3.03 or later, specifically designed for CENTUM VP and CENTUM CS 3000 systems.

Product Parameters

Power Supply: Supports dual voltage ranges of 100–120 V AC or 220–240 V AC at 50/60 Hz.
Power Consumption: Maximum 20 VA.
Operating Voltage (Internal): 5 V DC ± 5% supplied via the USB port of the computer.
Current Consumption: Maximum 1 A.
Dimensions: 440 mm (Width) x 284 mm (Depth) x 52 mm (Height). The height increases to 73 mm when the adjustable feet are extended.
Weight: Approximately 2.5 kg (including the AC adapter).
Operating Temperature: 5°C to 40°C.
Ambient Humidity: 20% to 80% RH (non-condensing).
Color: Frosty White (Munsell No. 2.5Y8.4/1.2).

Product Advantages

Dedicated Process Keys: Features 32 "one-touch" function keys that allow operators to instantly call specific windows or initiate application programs, significantly reducing response time during critical events.
Industrial Durability: Its dust-proof and drip-proof flat surface ensures long-term reliability in industrial settings where standard consumer keyboards might fail.
Enhanced Feedback: The integrated USB speaker ensures that alarms are heard directly at the operator station, even if the PC's internal speakers are muted or absent.
Ease of Connection: The plug-and-play USB interface simplifies installation and reduces the complexity of wiring compared to older proprietary serial keyboards.
Ergonomics: Designed for extended use, the keyboard layout follows the specific operational logic of Yokogawa DCS systems, making it intuitive for trained plant operators.

Important Considerations (Precautions)

Usage Limitation: Only one AIP827-1 operation keyboard can be used per desktop Human Interface Station (HIS).
Power Connection: Ensure the AC adapter is connected to a power source that matches the specified voltage range (100–120 V or 220–240 V) to avoid damaging the internal sound function circuitry.
Touch Sensitivity: The touch-sensitive keys are designed for use with bare hands; they may not respond accurately if used with heavy industrial gloves.
Lifecycle Status: The AIP827-1 is largely considered a legacy/discontinued product. For new system installations, Yokogawa typically recommends the newer AIP830 series.
Cleaning: Use a damp, soft cloth for cleaning. Avoid using harsh chemical solvents that could degrade the flat-panel membrane or the paint finish.

Product Applications

The AIP827-1 is primarily utilized in large-scale industrial plants that rely on Yokogawa's automation platforms.

Oil and Gas Refineries: Used in central control rooms to monitor complex distillation and cracking processes.
Power Plants: Employed by operators to manage turbine controls, boiler parameters, and electrical distribution.
Chemical Processing: Used to supervise batch and continuous reactions where rapid access to trend curves and alarm logs is vital.
Water and Wastewater Treatment: Provides an interface for monitoring remote pumping stations and chemical dosing systems.
Pharmaceutical Manufacturing: Facilitates precise control and monitoring required for highly regulated production environments.
