8.4 Analogue module
The analogue module (order no. LRZ 912) has 2 inputs and 2 outputs which are brought out on a 6-pole DIN
socket to Namur Recommendation (NE28). The inputs and outputs can be set independently as 4 – 20 mA,
0 – 20 mA or 0 – 10V interface. Various functions can be selected for the inputs and outputs. Accordingly, the
signal on the input is interpreted differently and different information is output via the output connection.
In addition the interfaces can be scaled freely according to the set function.
For measuring transducer is 20 V DC available.
The following values can be specified via the inputs:
-
setpoint temperature with function:
MN tS
or Set temperature ,
-
external actual temperature with function:
MN tE
or ext. actual temperature ,
-
Pump power with function:
MN PP
or Pump power .
The following values can be specified via the outputs:
-
Setpoint temperature with function: Master:
MN tS
or Command: Set temperature ,
-
The temperature source with which active control occurs:
MN tC
Controlled temp. ,
-
Actual temperature (bath temperature):
MN t1
or Internal Temp. ,
-
External actual temperature from Pt100:
MNtEP
or Temp.external Pt100 ,
-
External actual temperature from analogue input:
MNtEA
or Temp.external analogue ,
-
External actual temperature from the serial interface:
MNtES
or Temp.external serial ,
-
Actuating signal:
MN Y
or Actuating signal ,
-
Pump power:
MN PP
or Pump power ,
-
Pump speed:
MNtEn
or Pump speed .
In addition the interfaces can be scaled freely with
L =0
/
H 10=0
in % or
minimal value / maximal value according to the set function.
For example: 4 mA corresponds to 0 °C and 20 mA corresponds to 100 °C.

Connection of the analogue inputs and outputs
A 6-pole round connector with screw locking and contact arrangement according to DIN EN 60130-9 or
IEC 130-9 is needed.
A suitable coupling plug can be obtained under order no. EQS 057.
