Analog module

The following values can be defined via the inputs:
Set-point temperature
–
Ext. Actual temperature
–
Pump power
–
The following values can be output via the outputs:
–
Set-point temperature
–
Controlled temp.
–
Internal temp.
–
Temp.extern Pt100
–
Temp.extern analog
–
Temp.extern serial
–
Set value
–
Pump power
–
Pump speed
–
In addition the interfaces can be freely scaled according to the set function with
maximal value.
For example: 4 mA corresponds to 0 °C and 20 mA corresponds to 100 °C.
Accuracy of the inputs and outputs after calibration better than 0.1 % of full scale.

Analogue Module (LAUDA catalogue no. LRZ 912) has two inputs and two
outputs, which are brought out to a six-pole DIN socket to Namur Recom-
mendation (NE28).
The inputs and outputs can be set independently of one another as a 0 –
20 mA, 4 – 20 mA or 0 – 10 V interface; Various functions can be selected
for the inputs and outputs. Accordingly, the signal on the input is interpreted
differently and different information appears on the output.
In addition the interfaces can be freely scaled according to the set function.
20 V DC is available for measurement transducers.
