FFI SYSTEM
OPTICAL MULTI-POINT TEMPERATURE CONVERTER
FRL…2
DATA SHEET
This multi-point temperature converter receives up to 16
inputs from thermocouples or resistance bulb temperature
sensors and converts them into optical digital output signals.
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 disconnection, measured value abnormality and the like are built
in and such data can be transmitted to the host system.
