EDS9-46E Datasheet, PDF (1/4 Pages) Fuji Electric – OPTICAL MULTI-POINT TEMPERATURE CONVERTER

FFI SYSTEM
OPTICAL MULTI-POINT TEMPERATURE CONVERTER
DATA SHEET
FRL…2
This multi-point temperature converter receives up to 16
inputs from thermocouples or resistance bulb temperature
sensors and converts them into optical digital output sig-
nals.
This articles are φ 6mm optical fiber cable connection type.
FEATURES
1. The temperature measuring data for up to 16 points can
be transmitted to a host system via a single optical-fiber
cable.
2. Zero point and span setting can be executed from the
host system.
3. Diagnosis functions for temperature sensor discon-
nection, measured value abnormality and the like are built
in and such data can be transmitted to the host system.

–200 to 300°C 60 to 300°C span
–200 to 600°C 120 to 600°C span
Zero point shift: Within a range of –200 °C to +80% of
maximum span
Measuring range should not be exceeded.
Output signal: Optical digital output
Power supply: 24V DC (20 to 30V DC)
100/115/220V AC ± 10% 50/60Hz
Power consumption:
Approx. 2W(24V DC) or approx. 10VA
(100V AC)
Remote setting: By hand-held communicator or master
station.
Zero point, span. memory read/write
Self-diagnosis: Results are sent to master station.
Measured value abnormality, battery
voltage drop, temperature sensor dis-
connection, internal temperature.
Explosion-proofing:
JIS i3aG4, i2G4 intrinsically safe explo-
sion-proofing
Possible only for 8-point inputs with
24V DC power supply. A safety barrier
(PWXBA001) for 24V DC should be pre-
pared separately.

–30 to +60°C
Storage temperature:
–30 to +70°C
Ambient humidity:
90% RH or less
Transmission: Half-duplex bidirectional transmission via
single optical-fiber cable.
Transmission distance: 1.2 km maximum
