ASCO™ Series RCS Redundant Control System
Series RCS
The ASCO Series RCS redundant control system is the only 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. The availability and reliability of The ASCO Series RCS provides the customer´s best choice for process valve diagnostics and actuation.
