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