EDS9-51A Datasheet, PDF (1/4 Pages) Fuji Electric – OPTICAL SWITCH CONVERTER

FFI SYSTEM
OPTICAL SWITCH CONVERTER
DATA SHEET
FRS
This instrument receives up to 16 optical ON/OFF signals
from optical limit switches or optical pressure switches and
converts them into optical digital output signals.
FEATURES
1. A maximum of 16 optical switch signals can be transmit-
ted to a host instrument via a single optical cable.
2. An FFI system including a combination of temperature,
pressure, flow rate and other signals can be configured.
