Product Description

Overview
The Yokogawa AIP171 is a dedicated Operator Keyboard Interface Card designed for CENTUM VP and CENTUM CS 3000 distributed control systems. It enables the connection of professional Yokogawa operator keyboards to a Human Interface Station (HIS), providing instantaneous response for critical control functions that standard keyboards cannot deliver.

Key Features

Dedicated Interface Logic
The AIP171 is built to handle the unique scan codes of Yokogawa operator keyboards. Every keystroke, including emergency and alarm commands, is processed deterministically, ensuring precise system response with no input delay.

Integrated Sound Controller
The card manages electronic beeps and alarm sounds directly from the keyboard. This independent auditory channel ensures operators receive timely audio feedback even if the HIS sound card is unavailable.

Power Delivery to Keyboard
The interface card supplies the necessary power to the operator keyboard via its connection cable, eliminating the need for external adapters and simplifying the operator station setup.

Industrial-Grade Reliability
Engineered to meet Yokogawa’s industrial standards, the AIP171 operates continuously in control room environments. It provides high electromagnetic compatibility (EMC) to prevent interference with other critical devices.

System Integration
Fully compatible with the CENTUM software stack, the card is automatically recognized by HIS utilities. Operators can adjust keyboard sensitivity and sound levels directly through the standard system configuration interface.
