EDS9-21C Datasheet, PDF (1/4 Pages) Fuji Electric – FC SERIES PT TYPE SIGNAL CONVERTER

FC SERIES PT TYPE SIGNAL CONVERTER
DATA SHEET
The FC series PT type signal converter converts inputs
from a thermocouple, resistance bulb, DC voltage and cur-
rent into a signal of isolated 1 to 5V DC or 4 to 20mA DC.
In addition, burnout protection in the event of thermo-
couple breakage, transmission function are avaiable.
Its structure is plug-in style.
