Analog module
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 Recommendation (NE28).
The inputs and outputs can be set independently of one another as
a 0...20 mA and 4...10 V interface, Various functions can be se-
lected 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.
The following values can be defined via the inputs:
−
Set-point temperature
Setpoint temperature
−
Ext. Actual temperature
External actual temperature
−
Pump power
Pump power
The following values can be output via the outputs:
−
Set-point temperature
Set-point temperature
−
Controlled temp.
The temperature to which the system is being controlled.
−
Internal temp.
Actual temperature (bath temperature)
−
Temp.extern Pt100
External actual temperature of Pt100
−
Temp.extern analog
External actual temperature of the analogue input
−
Temp.extern serial
External actual temperature of the serial interface:
−
Set value
Set value
−
Pump power
Pump power
−
Pump speed
Pump speed
In addition the interfaces can be freely scaled according to the set function with
minimal value
and
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.
