Combining the robust design and compact dimensions typical of a PLC with the advanced capabilities and smooth integration of the Ovation control system, this compact controller stands out as a reliable automation solution, adaptable for a variety of power generation or water and wastewater applications that necessitate localized management. It not only boosts reliability and reduces costs through efficient and secure remote asset management from any location, but it also supports advanced applications that significantly improve plant performance. Additionally, Ovation includes features such as integrated vibration monitoring, generator excitation control, safety instrumented systems (SIS), and flexible configurations suitable for both small and distributed environments. Its capabilities extend to virtualization and embedded simulation tools, ensuring it remains a comprehensive choice for contemporary industries. This multifaceted design guarantees that it can address a wide range of operational requirements while upholding stringent efficiency and safety standards, making it an invaluable asset in the field.

ProSafe-RS Lite complies with the international safety standard appropriate for applications rated up to SIL2. The ProSafe series provides a range of options including SIL2 (ProSafe-RS Lite), SIL3 (ProSafe-RS), and SIL4 (ProSafe-SLS), offering adaptability in implementing safety solutions. Continuous enhancements to the ProSafe series aim to further bolster the safety of operational plants. The safety integrity level (SIL) concept, introduced by the International Electrotechnical Commission (IEC), evaluates the effectiveness of safety functions and is categorized into four tiers from SIL1 to SIL4, as specified in IEC 61508. In contrast to environments without safety measures, SIL2 significantly reduces risk, bringing it down to between 1 in 100 and 1 in 1,000. At a SIL3 level, this risk diminishes even more, falling between 1 in 1,000 and 1 in 10,000, while SIL4 achieves an exceptional risk factor of between 1 in 10,000 and 1 in 100,000. ProSafe-RS Lite leverages the established reliability of ProSafe-RS technology, and its seamless integration with CENTUM VP/ProSafe-RS allows for a unified strategy in both safety management and process oversight. This collaboration not only improves operational productivity but also strengthens the dedication to upholding rigorous safety standards within industrial environments. By prioritizing safety and efficiency, organizations can create a more secure and productive workplace for their employees.

The ProSafe-RS safety instrumented system has received TÜV certification for deployment as a Safety Instrumented System (SIS) in SIL 1, 2, and 3 applications, all within a single modular configuration that enhances availability when set up redundantly. It is capable of operating as an independent unit or integrating flawlessly with the CENTUM VP Distributed Control System. Yokogawa’s solutions for industrial safety prioritize minimal interruptions by providing reliable protection across all SIL levels, featuring real-time dashboards that assess both current and potential risks, as well as virtual scenario testing to evaluate the consequences of possible bypasses and overrides. Additionally, the system allows for online changes, facilitating continuous operation during upgrades, and it automates compliance reporting to improve testing intervals while offering extensive service and lifecycle support. Serving as a vital last line of defense, the safety controller is engineered for dependable performance exactly when it is crucial. Moreover, Yokogawa's innovative Versatile Modular Redundancy guarantees ongoing SIL 3 functionality even in the face of multiple failures, underscoring the system's durable design. This adaptability is not only vital for ensuring safety but also for optimizing operational efficiency in intricate industrial settings, where reliability is paramount. Ultimately, the ProSafe-RS system exemplifies how advanced safety technologies can meet the challenges of modern industrial processes.

ProSafe-SLS is a cutting-edge, hard-wired safety instrumented system developed by Yokogawa to meet the highest safety integrity standards. Tailored to address the specific demands of various safety instrumented systems, this product line supports all safety integrity levels (SIL 3-4) across multiple industries, including oil and gas, petrochemicals, chemicals, nuclear power, and traditional energy generation. Furthermore, the ProSafe-SLS system integrates effortlessly with Yokogawa's CENTUM VP process control platform and the FAST/TOOLS SCADA software suite. Its modular design allows for the development of a wide range of applications, from compact HIPS systems to large-scale ESD and F&G systems, all while achieving rapid response times to satisfy diverse process needs. Specifically engineered for environments that require the highest Safety Integrity Levels (SIL 3 and 4), the ProSafe-SLS employs solid-state components to perform its functional logic with great efficiency. This combination of capabilities positions ProSafe-SLS as a prime choice for sectors where safety is critical, ensuring that operations can proceed without unnecessary risks. Its reliability and adaptability further enhance its appeal in industries focused on maintaining the highest safety standards.

Contemporary operators face the challenge of reducing both capital and operational costs while also minimizing unexpected downtime and maintaining compliance with the safety standards specified in ISA84/IEC 61511. Is your facility well-equipped to monitor critical data regarding safety system performance and adherence to regulations? Yokogawa’s Sustainable Functional Safety Management (FSM) solution plays a pivotal role in evaluating safety action demands and failures in process operations against established Safety Performance Indicators throughout the entire lifecycle of a plant. This continuous assessment ensures that all personnel on-site receive timely updates regarding safety performance, which is vital for maintaining operational efficiency. Furthermore, effective management of safety information promotes sustained compliance with IEC 61511 and ISA84 over the asset's lifespan. Following the completion of the safety instrumented system (SIS) design and layer of protection analysis (LOPA), the process safety monitoring setup is simplified through automation. Our FSM solution not only streamlines these processes but also enhances efficiency by automating change management, thereby ensuring that safety protocols are consistently upheld and improved over time. Embracing this innovative approach helps organizations stay ahead in their safety management practices, ultimately fostering a safer working environment.
