Ropex CIRUS UPT-640 - Output

9.7 Temperature indication/actual
value output
If the display is in the home position, the ACTUAL tem-
perature is indicated there as a digital value and as a
dynamic bar.
The heating and control process can thus be monitored
at any time.
In addition, the UPT-640 (as of SW 100) controller out-
puts an electrically isolated, analog 0…10VDC signal,
which is proportional to the real ACTUAL temperature,
at terminals 20+24.
Voltage values:
0VDC  0°C
10VDC  300°C or 500°C (depending on the
controller configuration).
The relationship between the change in the output
voltage and the ACTUAL temperature is linear.
Only the two temperature ranges 300°C and 500°C
appear at this actual value output. If a temperature
range of 200°C is set for the controller with step 205 in
the Configuration menu, it appears at this output in the
0…300°C range. A 400°C temperature range is indi-
cated as 0…500°C.
An indicating instrument can be connected to this
output in order to visualize the temperature of the heat-
sealing band.

meter (size, scaling, dynamic response) are ideally
