Yokogawa AIP827 CENTUM CS 3000 Operation Keyboard

Product Overview

The Yokogawa AIP827 is a specialized USB Operation Keyboard designed explicitly for Human Interface Stations (HIS) within the CENTUM CS 3000 and CENTUM CS 1000 Distributed Control Systems. Engineered to replace standard commercial keyboards in critical control rooms, this unit solves the reliability issues associated with consumer-grade peripherals by offering a dust- and drip-proof flat design that withstands harsh industrial environments. Compatible with software revision R3.03 and later, the AIP827 ensures secure, uninterrupted operator input for process monitoring and control, featuring universal voltage support (100-240 VAC) and rigorous compliance with international safety and EMC standards including CSA and CE.

Technical Specifications

Model Code Decomposition

Yokogawa’s part numbering for Human Interface Station peripherals like the AIP827 includes specific style identifiers to denote hardware revisions or regional power configurations. While the base number identifies the function, the suffixes are critical for ensuring physical and electrical compatibility.

Part Number: AIP827-S1

• AIP: The series prefix for CENTUM VP/CS 3000 peripheral and interface units.

• 827: The unique identifier for the USB Operation Keyboard unit. This distinguishes it from older PS/2 models or trackball-integrated units.

• -S1 (Style S1): This suffix indicates the specific hardware configuration and power supply bundle.

• S1: Denotes the "Standard" configuration equipped with a universal AC adapter capable of accepting both 100-120 VAC and 220-240 VAC inputs. It confirms the inclusion of the specific Frosty White housing and the USB Type-A interface cable required for HIS units running software revision R3.03 or later.

• Note: In some legacy catalogs, different suffixes (e.g., -S2) might indicate region-specific cable lengths or alternative voltage locks, but AIP827-S1 is the global standard for modern CENTUM CS 3000 installations requiring dual-voltage flexibility.

Installation Recommendations and Wiring Guidelines

Proper installation of the AIP827 is essential to maintain the integrity of the Human Interface Station and ensure operator safety in control room environments.

1. Software Verification: Before physical installation, verify that the CENTUM CS 3000 or CS 1000 HIS is running software revision R3.03 or later. Earlier revisions may not contain the necessary drivers to recognize the USB interface of the AIP827.

2. Power Connection: The unit requires an external AC connection via the included adaptor. Connect the power cord to a stable 100-240 VAC source. Ensure the power rating of the outlet exceeds 20 VA. Do not daisy-chain multiple high-load peripherals on the same low-capacity UPS outlet without calculating the total load.

3. USB Connectivity: Plug the USB Type-A connector directly into the designated USB port on the HIS workstation. Avoid using unpowered USB hubs, as they may not provide sufficient stability for real-time operation keys.

4. Environmental Placement: While the keyboard is dust- and drip-proof, it should be positioned to prevent liquid pooling around the cable entry point. Maintain the ambient temperature between 5°C and 40°C during operation.

5. Grounding and EMC: For units operating on 220-240 VAC, ensure the power outlet is properly grounded to satisfy CE and C-Tick EMC requirements. This prevents electromagnetic interference from affecting other sensitive control room instrumentation.

6. Cleaning: Due to the flat, sealed design, clean only with a soft, slightly damp cloth. Do not use abrasive cleaners or spray liquids directly onto the key surfaces to preserve the drip-proof seal.

Frequently Asked Questions (FAQ)

Q: Can I use the AIP827 keyboard with older CENTUM CS systems (pre-R3.03)?

A: No. The AIP827 utilizes a USB interface and specific drivers that are only supported in CENTUM CS 3000 and CS 1000 systems with software revision R3.03 or later. Older systems typically require PS/2 based operation keyboards.

Q: Is the AIP827 waterproof?

A: The keyboard is rated as "dust- and drip-proof." It can withstand accidental spills and humid environments typical of control rooms, but it is not submersible and should not be subjected to high-pressure water jets.

Q: Does the package include the power adapter?

A: Yes, the standard AIP827-S1 package includes both the keyboard unit and the compatible AC adaptor, with a total weight of approximately 2.5 kg.

Q: What is the difference between the AIP827 and a standard industrial keyboard?

A: The AIP827 is pre-configured with specific function keys and layouts optimized for Yokogawa’s Human Interface Station software. It ensures seamless integration with the CENTUM operator interface, whereas standard keyboards may lack specific macro keys or require complex remapping.

Q: Can I operate this keyboard on a 24 VDC power system?

A: No. The AIP827 is designed strictly for AC power inputs (100-120 VAC or 220-240 VAC). It does not support direct 24 VDC connection.
