A. Functions of Electronic Temperature Controller
Features
The electronic temperature controller is a digital type ON/OFF controller used to control
fluid temperature.
Structure
The electronic temperature controller is composed of the following components:
1. Control substrate
This is the main CPU device composed of the CPU itself, the power circuit, sensor
input, and relay and display outputs.
2. Transformer
The transformer supplies the 10-V power supply necessary for the power circuit of
the control PCB.
3. Display PCB
This consists of switches required for the display, a 7-segment LED display screen
which displays parameters and other data, and a RUN lamp which indicates the
current operating condition of the controller.
