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