Product Performance
Accurate Conversion: It can accurately convert the input 4-20mA current signal into the corresponding pneumatic pressure output, achieving precise current pressure conversion and helping to accurately control the position of steam turbine valves.
High stability: With minimal drift and high repeatability, it ensures consistent and reliable performance, enabling precise valve positioning, improving the accuracy of steam turbine speed and load control, and reducing system mechanical wear.
Strong anti pollution ability: Designed to withstand oil pollution (up to ISO 20/16 standard), it can work reliably in harsh industrial environments, solving the industry problem of oil pollution affecting the normal operation time and performance of equipment.
Having redundancy function: providing redundant inputs and outputs, capable of receiving signals from redundant controllers, with redundant (dual) CPCs (master/slave) function, enhancing safety and reliability in critical applications.
Self diagnostic function: It has status and health indication functions, can monitor the health of pressure sensors, input demand signals, internal unit health, and input power quality, and has control pressure readings and software service tools for trend analysis.
