Task:
Let's say that we would like to control temperature (around 30°C) in some room by
switching ON and OFF an electric heater. The hysteresis should be 5°C. The temperature is
measured using a PT100 sensor and
RT4
input module, and let the heater is controlled using
an internal 5A relay (
R45
module).
Solution:
First configure the device as described below, then connect the object and power supply
as shown on Fig. 7.92 .
Fig. 7.92.Schematic diagram for the RTD input and Relay output modules
To control temperature in object shown on
Fig. 7.92
, it is necessary to configure one
Logical channel
and
Relay output
.
For reading PT100 sensor temperature:
– touch screen and press the Menu button,
– press the Device configuration button,
– enter the Logical channels menu,
– using the arrows in the top navigation bar, select any Logical channel such as 1 ,
