5.6 Analog input module 8 AI eco
The analog input module
romod 8 AI eco
is used
for connecting and measuring of up to eight
analog sensor values.
The sensors will be connected to the module via
terminals.
The reference potential for the analog inputs is
available at the GND terminals. For two AIs there
is available one GND terminal in each case. All
ground pins are connected to each other
internally and to the GND of the power supply, as
well.
Active signals (0-10V) as well as various passive
sensor types (e.g. Pt1000, Ni1000) may be
connected to the module.
Unused inputs should be configured for 0-10V
signals and connected to GND potential.
Regarding the system configuration (addressing,
maximum number of modules connected to a
MODBus
Master
interface,
installation,
connection to the bus etc.), please follow the
instructions in the chapter
Configuration
.
