Fuji EDS9-44E Optical signal converter Datasheet

FFI SYSTEM
OPTICAL SIGNAL CONVERTER
DATA SHEET
FRK
The optical signal converter performs conversion between optical and electrical signals of FFI system specifications, and serves as an interface when connecting a
detector or controlled element of an electronic instrumentation system to the FFI system.
This is a high-precision intelligent instrument with a
built-in microcomputer for digital processing of signals.
Optical fiber is used in the signal transmission section
which enables forming an optical fiber type field instrumentation system (FFI system) together with optical
star coupler and master station.
FEATURES
1. Bidirectional transmission system
Transmission of measured data and fault diagnosis
data to the host computer and remote settings etc.
from the host is done bidirectionally via a signal optical
fiber cable.
2. Easy adjustment and setting operation
Adjustment and settings can be made easily via remote
operation from the host computer or by key switches
on the indicating unit (option).
3. Self-diagnosis function
A number of self-diagnoses are possible by the builtin microcomputer.
4. Digital display type field indicator available at option.
5. Flame-proof structure (d2G4) can be provided at
option.

Other:
Optical output alone can be provided by
combining the electrical/optical converter
with an optical receiving converter (type
PRN).
In this case the transmission distance is
4 km max.
