The Yokogawa AIP831 is an advanced operation keyboard (operator interface unit) designed for Yokogawa CENTUM VP Distributed Control System (DCS).
It is specifically engineered for eight-loop simultaneous operation, allowing plant operators to monitor and control multiple process loops efficiently from a single desktop Human Interface Station (HIS). The unit integrates touch-sensitive function keys, alarm handling features, and audio feedback, enabling fast and intuitive control in critical industrial environments.
The AIP831 is widely used in control rooms of oil & gas, petrochemical, chemical, and power generation plants, where operators require high-speed multi-loop control with maximum reliability.
