Analogue module
Analogue Module (LAUDA order 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 selected for the inputs
and outputs. Accordingly, the signal on the input is interpreted differently and dif-
ferent 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:
−
setpoint temperature with the function
Setpoint temperature
.
−
external actual temperature with the function
Ext. actual temperature
.
.
−
Pump power with the function
Pump pow.
.
The following values can be output via the outputs:
−
setpoint temperature with the function
Setpoint temperature
.
−
The temperature controlled:
Controlled temp.
.
−
Actual temperature (bath temperature):
Internal temp.
.
−
External actual temperature of the Pt100:
Temp.extern Pt100
.
−
External actual temperature of the analogue input:
Temp.extern analog
.
−
External actual temperature of the serial interface:
Temp.extern serial
.
−

.
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.
