Product Introduction
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.

Frequently Asked Questions (FAQ)
-
What systems is the AIP831 compatible with?
The AIP831 is fully compatible with Yokogawa’s CENTUM VP and CENTUM CS 3000 systems. It is not intended for standalone or third-party systems. -
What distinguishes the AIP831 from the AIP830?
The AIP831 supports dual operator use, whereas the AIP830 is for single-station applications. It also includes additional keys and ports for multi-user functionality. -
Can it be mounted in control consoles?
Yes, the AIP831 can be either console-mounted or placed on a desk. It’s designed for flexible integration into various control room setups. -
Does the keyboard require software installation?
No software installation is necessary. The AIP831 is a plug-and-play device within Yokogawa systems. -
What are the primary functions available on the keyboard?
It includes keys for alarm acknowledgment, display switching, command input, and navigation within the operator interface screens. -
Is it hot-swappable?
For USB models, limited hot-swapping is supported. For PS/2 models, the device should be connected before system boot for full functionality. -
How is power supplied to the AIP831?
Power is supplied via the communication port (USB or PS/2), so no external power adapter is needed. -
Are the keys backlit or do they have status indicators?
The keyboard features LED status indicators, but it does not have individual key backlighting. -
Is the keyboard programmable?
