Model STED (Style S) mV, Temperature and Potentiometer/ Voltage Converter

GS 01B04J01-02E

n 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: xed input type that is xed 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.

With the VJ77 Parameter Setting Tool you can do the following:

· Read/write all parameters at once

· Save read parameters to a le

· Copy parameters to other devices of the same model

and sux code (only with style code R or S).
