Yokogawa AIP831 Operation Keyboard

The Yokogawa AIP831 is a dual-station operation keyboard designed for high-reliability control and monitoring tasks within Yokogawa’s CENTUM CS 3000 and CENTUM VP Distributed Control Systems (DCS). Built for process control operators who manage critical infrastructure, this keyboard offers enhanced accessibility, redundancy support, and fast-action input functionalities.

Unlike standard commercial keyboards, the AIP831 is optimized for operator stations in industrial control rooms. With dedicated function keys, alarm acknowledgment shortcuts, and robust tactile switches, it facilitates fast, efficient, and safe operations across redundant or multi-display environments. The AIP831 is essential for ensuring accurate operator interaction under both routine and emergency conditions.
