GENERAL
The Model STED Converter accepts a mV DC,
thermocouple, RTD or potentiometer signal, converts
and normalizes it, provides isolation, and outputs 1
to 5 V DC and 4 to 20 mA DC signals. Two types
are prepared for the STED converter: fixed input
type that is fixed to mV DC, thermocouple, RTD
or potentiometer, and universal input type that can
select input type from mV DC, thermocouple or RTD.
Burnout function is provided as standard for each
type.
