data sheet this instrument converts the optical signal from a mas- ter station or the like into a pneumatic signal (0.2 to 1.0 kgf/cm 2 , etc.) in order to drive a diaphragm type control valve. the operating position of the valve is fed back via link to this positioner to enable accurate positioning. a built-in microcomputer provides intelligent digital pro- cessing of signals with a high precision, and the use of a piezo- electric element flapper makes for a low power consumption. this articles are 6mm optical fiber cable connection type. ambient humidity: 0 to 95%rh transmission: half-duplex bidirectional optical transmis- sion system using single optical fiber cable transmission distance; 1.2km max.
