Analog Control
The change in current output of the
Temperature Controller between 4 and 20 mA
is used for precise heater control by the G3PX,
which outputs smoothly adjusted power. Fine
adjustments of the heater temperature are
possible with external or internal duty setting.
ON/OFF Control
Fine adjustments of duty setting output voltage are possible.

The voltage output of the Temperature
Controller is used for ON/OFF heater control.
Fine adjustments of the heater temperature
are possible with external or internal duty
setting.
Manual Control
Output adjustments are possible with an
external variable resistor.
