The FY301 microprocessor based positioner provides fast and accurate positioning of diaphragm or cylinder actuators. The FY301 produces a pressure output as required to position a control valve according to a 4 to 20 mA input signal supplied by a controller. The FY301 is part of SMAR's complete 301 series of smart devices.
