Safety Video Display Unit

Digital control and protection systems offer improved accuracy, reliability, and flexibility when compared to their analog counterparts. A digital display unit is a natural human-machine interface in these types of systems.

A digital display unit provides the ability to display validated signals from multiple, independent channels in context with other information, enabling more effective decision-making. The flexibility of graphics design resolves identified difficulties by providing the correct information set in context with the control features. Specific graphics can be configured to support individual decisions or actions for normal, abnormal or emergency operations.

The Triconex Safety Video Display Unit (SVDU) is an operator workstation that provides Human Machine Interface (HMI) functionality for nuclear safety-related applications. The SVDU consists of a server and a flat panel monitor and multiple SVDU systems can be configured to interface with a network of multiple safety systems. The server runs the QNX™ operating system and the Advanced Control Center Information System (ACCIS™) software (preloaded) that supports the communication, display and entry of safety-related process data between the SVDU and the safety system.
