Yokogawa designers have employed state-of-the-art electronic design techniques and component packaging to miniaturize the safety controller circuitry. Every ProSafe-RS processor, input module, and output module features a dual architecture, providing users with SIL3-level protection on a single card. This architecture is simplicity itself to understand, design, install and maintain. Complete safeguarding now comes in one box. Furthermore, the design has an extremely high diagnostic coverage factor of more than 99%, providing users with a means of rapid fault detection that can allow repairs to be effected within an acceptable period - with minimal impact on the process.
