USB interface device (type B). Software updates (updater) are installed
n
on the device via this interface (no process interface).
The USB interface host (type A) allows the connection of a USB drive.
n
This interface can be used, for example, for data import, data export and
software updates (no process interface).
The Ethernet interface enables the connection to a control station or a
n
PC. This interface offers the customer the opportunity to control and
monitor their temperature control processes via a LAUDA interface
command set (process interface).
In the case of the Integral XT FC, the connecting cable of the flow
n
control unit is connected to the LiBus interface (marked with LiBus).
The device must be equipped with an additional Pt100 LiBus module
if the Command Touch remote control or the module box is to be
connected.
The external Pt100 temperature probe is connected to the Pt100 inter-
n
face (marked with the label Pt100).
Potential-free contact (marked with label OUT), with built-in connector
n
(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.
The analog module (order no. LRZ 912) has a 6-pin socket with two
n
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
n
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.
