3.1.5 Analog Temperature Tuning Input
The set temperature "TSET" can be tuned by applying a voltage to the input "TUNE IN" (R1) at
the rear panel of the TED200C. The temperature set value is proportional to the sum of the
signal at input "TUNE IN" (R1) and of the value set with the adjustment knob (F10).
The tuning range for the analog control input "TUNE IN" depends on the connected sensor:

Conversion Coefficient
TH 20 K
0 ... 20 kW
0 ... 10 V
2 kW/V
TH 200 K
0 ... 200 kW
0 ... 10 V
20 kW/V
AD590/592;
LM135/335
-45 °C...+145 °C
- 2.25 V...+7.25 V
20 °C/V
Note
Only slow variations of the temperature set value (<< 1 Hz) are possible via the analog control
input "TUNE IN".
The actual temperature "TACT"can be observed at the temperature monitor output "CTL
OUT" (R2).
3.1.6 Analog Temperature Output
The analog output "CTL OUT" (R2) delivers a DC voltage, proportional to the actual
temperature "TACT". The output voltage range depends on the used temperature sensor:

Conversion Coefficient
TH 20 K
0 ... 20 kW
0 ... 10 V
2 kW/V
TH 200 K

AD590/592;
LM135/335
-45 °C...+145 °C
- 2.25 V...+7.25 V
20 °C/V
To the analog output "CTL OUT" any measurement equipment can be connected directly.
Devices connected to these outputs should have an input resistance of 10 kW.
This monitor output is convenient to use for temperature monitoring e.g. during adjustment of
PID loop parameters.
