RES-402
Version 1
7.3
Temperature indication (actual value output)
The RES-402 supplies an analog 0…10VDC signal, which is proportional to the real ACTUAL temperature, at ter-
minals 11+12.
Voltage values:
0VDC
0°C
10VDC
300°C (ATR-3)
The relationship between the change in the output voltage and the ACTUAL temperature is linear.
An indicating instrument can be connected to this output in order to visualize the temperature of the heatsealing
band.
The characteristics of the ROPEX ATR-3 temperature meter (size, scaling, dynamic response) are ideally suited
to this application and this instrument should therefore always be used (
section 12 "How to order" on page 31).
It not only facilitates SET-ACTUAL comparisons, but also enables other criteria such as the heating rate, set point
reached within the specified time, cooling of the heatsealing band etc. to be evaluated.
