Additional interfaces
V6
Additional interface modules can be installed in the devices.
The Analog module (order no. LRZ 912) has a 6-pin DIN socket with

two inputs and two outputs. The inputs and outputs can be configured as
a 0 - 20 mA, 4 - 20 mA or 0 - 10 V interface independently of one
another. A voltage of 20 V applied to the socket supplies power to an
external sensor with electronic evaluation unit.
The RS 232/485 interface module (order no. LRZ 913) is available

in a 9-pin SUB-D socket design. Galvanically isolated by an optocou-
pler. When combined with the LAUDA command set, the module is
compatible with the ECO, Variocool, Proline, Proline Kryomat, PRO,
Integral XT and Integral T product lines. The RS232 interface can be
connected directly to the PC using a 1:1 contacted cable.
The contact module (order no. LRZ 914) is available in a plug connector

design according to NAMUR NE28. This contact module is identical
to LRZ 915, but only has two DIN sockets, each with one output and
one input. The coupling socket (order no. EQD 047) and the coupling
connector (order no. EQS 048) have a 3-pin design.
The contact module (order no. LRZ 915) is available in a 15-pin SUB-D

socket design. The module has three relay contact outputs (changeover
contacts, maximum 30 V/ 0.2 A) and three binary inputs for control via
external floating contacts.
Profibus module (order no. LRZ 917). Profibus is a bus system used

primarily in the chemical industry, which can connect a maximum of
256 devices at a high signal transmission rate.
EtherCAT module (order no. LRZ 922) with M8 connection sockets.

EtherCAT module (catalog no. LRZ 923) with connection via RJ45
sockets. EtherCAT is an Ethernet-based fieldbus with master/slave
functionality.
External LiBus module box (order no. LCZ 9727) with two additional

module bays. The number of LiBus interfaces can be increased using the
LiBus module box (LCZ 9727). Additional modules such as a solenoid
valve for regulating the cooling water or a reverse flow protection can
subsequently be connected.
Refer to the operating manual accompanying the relevant LAUDA interface
module for further information on connecting and using these interfaces.
