Serial interfaces RS232/ 485

RS232/ 485 Interface Module (order no. LRZ 913) with 9-pole SUB-D socket. Electrically isolated by
optocoupler. With the LAUDA instruction set essentially compatible to the Ecoline and Integral Series.
The RS232 interface can be connected directly to the PC with a 1:1 through-contact cable (order no.
EKS 037).
Interface description and commands see chapter 7.13.

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, o...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 are 24 V DC available.
The following values can be specified via the inputs:
-
-
-
The following values can be specified via the outputs:

In addition the interfaces can be scaled freely with
minimal value
For example:
− Accuracy of the inputs and outputs after calibration better than 0.1% F.S.
− Inputs, current
− Inputs, voltage
− Outputs, current
− Outputs, voltage
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.
