Product Overview
The Yokogawa AIP826-2 functions as the primary tactile control interface for CENTUM VP Human Interface Stations (HIS). This 100% brand new original module integrates a ruggedized operator keyboard with a dedicated power supply unit, providing a centralized point for process monitoring and command execution. Designed specifically for high-intensity control room environments, it allows operators to manage complex plant parameters across oil, gas, and petrochemical facilities with instantaneous response and deterministic accuracy.

Engineering Advantages
The AIP826-2 solves specific operational and environmental challenges inherent in industrial DCS consoles:
-
Optimizes Emergency Response: Unlike commercial keyboards, the AIP826-2 features dedicated function keys for alarm acknowledgement and window switching. This allows operators to navigate through high-density graphics and silence process alarms instantly during critical upsets.
-
Neutralizes Electrical Noise: Yokogawa engineers the internal circuitry with high-level EMI shielding. This prevents command latency or keyboard "ghosting" caused by the high-frequency interference often found in control rooms adjacent to power distribution centers.
-
Dual-Function Utility: This module serves as both a communication interface and a power distribution point. It supplies stable 24V DC power to nearby transmitters or workstation peripherals, reducing the need for separate power rails within the operator console.
-
Built for 24/7 Fatigue Resistance: The keyboard employs a compact, ergonomic layout that reduces wrist strain during 12-hour shifts. The heavy-duty mechanical switches provide clear tactile feedback, ensuring that every command registers even when operators wear protective gloves.
FAQs
Can I replace a standard PC keyboard with the AIP826-2 on my HIS station?
The AIP826-2 provides specialized hardware keys mapped directly to CENTUM VP software functions. While a standard keyboard handles basic typing, the AIP826-2 is essential for professional DCS operation, as it enables hardware-level alarm management and window call-up features.
Does the AIP826-2 require a separate power cable?
The unit typically draws power from the HIS system or a dedicated 24V DC bus. It then stabilizes and distributes this power to ensure that the keyboard logic and connected I/O remain functional even during minor voltage fluctuations.
What is the expected lifespan of the mechanical keys?
Yokogawa rates these mechanical switches for millions of cycles. The AIP826-2 withstands the constant usage typical of 24/7 continuous process industries, far outlasting commercial-grade membrane keyboards.
Is this unit compatible with older CENTUM CS 3000 systems?
Yes, the AIP826-2 maintains backward compatibility with most CS 3000 Human Interface Stations, provided the workstation has the appropriate USB/Bus interface ports and software drivers installed.
