ProSafe-RS is a highly reliable safety instrument system (SIS) from Yokogawa. It features a modular design with redundant structures within each module and the ability to configure modules in redundant pairs. This structure maximizes both safety and availability while keeping costs relatively low. ProSafe-RS also offers flexible plug-and-play capabilities, allowing users to configure input, output, and processor modules with the exact redundancy they need to achieve the perfect balance of safety and economy.
The ProSafe‑RS safety instrument system integrates with Yokogawa's CENTUM DCS to provide SIL‑3 safety functions. Its modular design offers redundant CPUs, I/O modules and flexible VMR (Versatile Modular Redundancy) configurations for high availability.
The manual covers hardware specifications, installation, configuration, online maintenance, OTS training, and integration with DCS, SCADA and asset‑management systems, including networking via Vnet/IP and remote I/O up to 50 km. This manual is written in Chinese.

VMR stands for Versatile Modular Redundancy; it provides flexible plug‑in redundancy by allowing redundant CPU, input or output modules to be added for higher safety and availability.
A ProSafe‑RS system can handle up to 1 500 I/O points.
Remote I/O modules can be connected up to 50 km away using optical fiber.
The redundant CPU switches over within 10 ms, ensuring uninterrupted operation.
