The Yokogawa AIP826 is an industrial-grade operation keyboard (HIS operator interface unit) designed for Yokogawa CENTUM CS / CENTUM VP Distributed Control Systems.
It is widely used in control rooms where operators require fast, tactile access to process control functions, alarm acknowledgment, and loop operation. Unlike standard PC keyboards, the AIP826 is engineered specifically for real-time industrial process interaction, ensuring stability, responsiveness, and ergonomic operation in mission-critical environments.
This model is a key component in legacy and existing Yokogawa DCS installations, especially in oil & gas, petrochemical, and power generation plants.
