FOXBORO定位器SRD998系列介绍

The intelligent positioner SRD998 is designed to operate pneumatic valve actuators and can be operated from control systems (e.g. the I/A Series System and Evo™), controllers or PC-based configuration and operation tools such as the FDT/DTMs VALcare™. The positioner is available with HART 7 Communication Protocol. The extra large multi-lingual full text graphical-LCD, in conjunction with the rotary selector, allows a comfortable and easy local configuration and operation. For installations in contact with explosive atmospheres certificates are available.
