The Yokogawa AIP830-111 is a specialized Operation Keyboard designed for the CENTUM VP and CENTUM CS 3000 Human Interface Stations (HIS).

Unlike a standard PC keyboard, it is purpose-built for the rigors of a 24/7 industrial control room, providing tactile, high-speed access to critical plant functions.

1. Introduction

The AIP830-111 is an essential tool for plant operators, featuring dedicated keys for alarm management, window switching, and process control (such as Open/Close or Increase/Decrease).

The “-111” suffix typically denotes the specific interface and mounting style (often USB-based with a specific language or layout configuration).

It allows operators to respond to emergencies instantly without navigating through multiple on-screen mouse menus.

4. Application Cases

Central Control Rooms (CCR): The primary interface for operators in refineries, chemical plants, and power stations.

Emergency Response Stations: Used where rapid, error-free input is required during a process upset or trip.

Operator Training Simulators (OTS): Providing a realistic hardware interface for trainees to learn plant “muscle memory.”

Consolidated Control Centers: Where multiple DCS domains are managed from a single desk.
