1 General
Many types of LAUDA constant temperature equipment have vacant
module slots for installing additional interfaces. The number, size and
arrangement of the module slots vary depending on the device and are
described in the operating manual accompanying the constant temperature
equipment. Two additional module slots available as accessories can be fitted
to a LiBus module box, which is then connected as an external casing to the
LiBus interface on the constant temperature equipment.
This operating manual describes how to install and configure the following
interface modules:

4 Device description
4.1 Purpose
The contact module is used to set or query binary states of the constant
temperature equipment by opening and closing circuits:
Output state (read): The module activates the circuit of the defined
interface function, see ÄChapter 7.2.1 “Read commands” on page20.
Set state (write): The user activates the circuit of the defined interface
function from outside the module, see ÄChapter 7.2.2 “Write com-
mands” on page21.
4.2 Versions
Choosing the most suitable version depends entirely on the scope of control
required:
Contact module with single input and output (NAMUR): One switching
function and one query can be configured for one input and one output,
which is enough to switch the constant temperature equipment between
operating and standby mode as well as monitor the temperature, for
example.
Contact module with 3 inputs and outputs: There are three inputs and
three outputs to which you can assign various switching functions and
queries.
Only one of the two versions can be operated for each item of
constant temperature equipment. This is particularly important to
note when integrating additional modules via the module box.
4.3 Structure
Contact output ( OUT ) and contact input ( IN ) on interface module
LRZ 927 are implemented using two 3‑pin connections.
