FFI SYSTEM
OPTICAL-PNEUMATIC CONVERTER
DATA SHEET
ZLD
The optical-pneumatic converter is used to convert optical signal from master station, etc. to pneumatic signal (0.2
to 1.0kg/cm 2 etc.). 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.
