The ASCO Series RCS redundant control system is a pilot valve system with no single point of failure that can result in unwanted closure of the process valve. It is suitable for use in SIL 3 applications and greatly reduces spurious trip rates. The ASCO Series RCS achieves a higher level of process safety and reliability by using a redundant, fault-tolerant architecture, high diagnostic coverage, and automated testing. It is available in a variety of constructions that provide valve diagnostics through automated, partial-stroke testing.
