Yokogawa releases enhanced version of ProSafe-RS Safety Instrumented System.
Yokogawa Electric Corporation has announced the release of ProSafe-RS R2.03.00, an enhanced version of the ProSafe-RS Safety Instrumented System. The enhancements include a new CPU module that is 3,5 to four times faster than the module used in the preceding version and a new digital output module that is intended for use with higher voltage devices. This new system satisfies users’ latest safety instrumentation requirements, improves efficiency and ensures operational safety.
Development background
There is a growing emphasis on safety instrumented systems for operational safety in energy and basic materials industries such as oil, natural gas, petrochemicals, and iron and steel that is driven by the need to provide a safe workplace, protect the environment, and be a responsible corporate citizen. Moreover, as companies around the world seek to achieve economies of scale and enhance competitiveness by building ever larger plants, there is a corresponding need for increased plant availability, higher operating speeds, larger capacity, and enhanced maintenance efficiency.
Hence the development effort to enhance the ProSafe-RS system with features such as a high-speed CPU module and a strengthened online maintenance function, targeted at international markets where many new large projects are planned.
Overview of enhancements
High-speed, large-capacity CPU module
A CPU module with a processing speed that is up to four times faster than the module used in the preceding version. The number of I/O points has been increased to 1500, an increase of nearly 50%, and application capacity has been increased 50%. These enhancements make the system ideal for use in large-scale plants.
New digital output module for high DC voltage
A digital output module has been added that enables ProSafe-RS to be directly connected to 48 VDC field devices such as valves. This elimination of the need to supply power through a relay allows a simpler and more cost effective system configuration that is easier to maintain.
Enhanced online maintenance
A function has been added that allows the installation of I/O modules without disrupting input/output to/from any connected devices. The scan frequency can also be changed online. This ability to reconfigure the safety instrumented system without halting plant operations improves productivity.
About ProSafe-RS
Released in February 2005, the ProSafe-RS Safety Instrumented System helps prevent accidents by detecting unusual conditions in plant operations and taking emergency actions such as shutting down the plant. Unlike conventional safety instrumented systems and DCSs, which are regarded as having different roles and functions and operate separately, the operation of ProSafe-RS and the CENTUM series can be fully integrated.
Applications are found in the oil, natural gas, petrochemicals, and other process industries that use systems for emergency plant shutdown, fire prevention and burner management.
