I do not understand the pin assignment on this temperature controller on pin 6 to 8.

This controller can work with a lot of different
AntwortenLöschentemperature sensors that are working completely
different.
There are Theromoelements that deliver/produce
a voltage, these are connected to 6 and 7
and there are thermoresistors like a PT100,
which have a variable resistance depending on the temperature, so there must be a constant
current to supply them.
I think pin8 is the output for this current
to supply thermoresistors.
this reqires thermoresistors to be connected
to 6 and 8.
I want to use a PT100 sensor.

look there:

with those data You can simulate the sensor!
Thanks Franz, you gave me the right direction.
AntwortenLöschenThe guys from JLD should improve their
AntwortenLöschenwiring diagrams a little bit.....
The connection between 6 and 7 is not easy
to see on the picture....
ok, now it is clear, as this are two pics
for the two main types of sensors.
I didnt see it in this way. Hmmmm......
