EDS9-47C

FFI SYSTEM OPTICAL-PNEUMATIC CONVERTER DATA SHEET The optical-pneumatic converter is used to convert optical signal from master station, etc. to pneumatic signal (0.2 to 1.0kg/cm 2 e tc.). It is installed in site when operating pneumatic final control element such as pneumatic positioner or diaphragm valve. Signals are processed in digital mode with built-in microcomputer, providing high accuracy and intelligent performance, adoption of piezo-electric element (flapper) has realized low-power operation. This instrument is φ6 mm optical fiber cable connection type.
