3.9 Interfaces
n
USB interface device (type B). Software updates (updater) are installed
on the device via this interface (no process interface).
n
The USB interface host (type A) allows the connection of a USB drive.
This interface can be used, for example, for data import, data export and
software updates (no process interface).
n
The Ethernet interface enables the connection to a control station or a
PC. This interface offers the customer the opportunity to control and
monitor their temperature control processes via a LAUDA interface
command set (process interface).
n
The Command Touch remote control unit or the module box can be
connected to the LiBus interface (marked with the label
LiBus
).
n
The external Pt100 temperature probe is connected to the Pt100 inter-
face (marked with the label
Pt100
).
n
Potential-free contact (marked with label
OUT
), with built-in connector
(after NAMUR NE 028) for program segment controlled signal trans-
mission for freely selectable peripheral functions to be activated (e.g.
alarm).
Different interface modules can be installed in the devices.
n
The analog module (order no. LRZ 912) has a 6-pin 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.
n
The RS 232/485 interface module (order no. LRZ 913) is available in
a 9-pin SUB-D socket design Galvanically isolated by an optocoupler.
When combined with the LAUDA interface command set, the module
is compatible with the ECO, Variocool, Proline, Proline Kryomat, PRO,
Integral XT and Integral T product lines. The RS 232 interface can be
connected directly to the control stand / PC using a 1:1 contacted cable.
n
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 1 output and 1 input on 2 sockets. The coupling
socket (order no. EQD 047) and the coupling connector (order no.
EQS 048) have a 3-pin design.
n
The contact module (order no. LRZ 915) is available in a 15-pin SUB-
D socket design. With 3 relay contact outputs (changeover contacts,
maximum 30 V/0.2 A) and 3 binary inputs for control via external
potential-free contacts.
n
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.
n
EtherCAT module (order no. LRZ 922) with M8 connection sockets.
EtherCAT is an Ethernet-based field bus with master/slave functionality.
