1 Introduction
1.1 Introduction
Generally most of the furnace applications require Controller and Recorder separately to
control and record the data. Some Furnaces application requires Ramp & Dwell controllers .The
new generation Paperless Recorder provides PID Control, Ramp & Dwell Control and Recording in
one device by using the new process control Card PC201 . This is a single loop controller for
Furnace applications. This will reduce Cost ,Space ,Wiring required for using controller and
Recorder separately.
1.2 Features
The Process Control Card has lot of unique Features on its hardware and Software. The
unique Features are listed below.
