With a module, the basic device is equipped with
a temperature measurement input. Temperature
measurement is carried out via the analog input
on terminals 27 and 28.
The measured values of the thermistor input are
obtained through determination of the average
value from cumulated resistance values. The
average value is converted to a temperature value
in the basic device and is displayed.
The basic device with module supports the
following temperature sensors:
·PT100 (default setting)
·PT1000
·KTY83
·KTY84
ATTENTION
Damage to the basic device, the module and/or
your system due to short circuit!
Inadequate insulation of the operating equipment
(such as temperature sensor) at the analog inputs
with respect to the supply circuits can cause
damage to your basic device, module and/or
system.
·
Ensure a reinforced or double insulation
of your operating equipment with respect
to the supply circuits!
·
Use shielded lines to connect
the temperature sensor!
·
Do not exceed a total load of 4 kΩ
(temperature sensor and cable)!
6.14 Ethernet interface
(only module 96-PA-RCM-EL)
The PC connection to the GridVis
®
software can
be made for the basic device with module 96-PA-
RCM-EL via the Ethernet interface.
When connecting the Ethernet interface, ensure
there is sufficient space in the connection area (at
least 50 mm), depending on the bending radius
and the plug type of the Ethernet cable. More
information on the Ethernet connection can be
found in the chap. „5.1 PC connection of the
basic device“ on page 18.
The communication settings for the Ethernet
connection of your basic device with module
96-PA-RCM-EL can be found in chap. „8.1 Basic
device communication via the Ethernet interface
(module 96-PA-RCM-EL)“ on page 30.
ATTENTION
Material damage due to incorrect network
settings.
Incorrect network settings can cause faults
in the IT network!
Consult your network administrator for
the correct network settings for your device.
NOTE
·Use a CAT5 cable for the connection to the
Ethernet interface.
·The standard factory setting of the basic
device with module is DHCP (dynamic
assignment of IP address)! More information
on the communication settings of the basic
device with module can be found in chap. “8.1
Communication of the basic device via the
Ethernet interface (module 96-PA-RCM-EL)” on
·The Ethernet settings can be easily configured
in the GridVis
®
software.

server or PC.
Example of temperature sensor:
A temperature sensor is used for measurement in
the proximity of non-insulated mains wiring in a
300 V CAT III network. Solution:
Use reinforced or doubled insulation for the
temperature sensor for the 300V CAT III network!
This corresponds to a test voltage of 3000 V AC (1
min. duration) for the temperature sensor.
