توضیحات محصول

The analog positioner SRI990 with analog input 4 to 20 mA is designed to operate pneumatic valve actuators. It offers easy adjustment by means of switches and potentiometers
The modular construction of this positioner series enables build-in options such as position feedback or limit switches. Thanks to the modularity, the common pneumatic sub assembly with the SRD family enable easy conversion from an analog to an "intelligent" positioner by exchanging the electronics. The SRI990 is available with a large choice of pneumatic relays from diaphragm versions to spool valve one to offer different air flow output capacities
