3.10. Sensor Connection
The analog and digital signal inputs and outputs are wired according to measurement task, to the transducer (sensor)
that is used, and to the number of connected sensors. The pinout arrangements for the various types of measurement
will be described in chapter 6. The respectively valid pin assignment is determined by means of the
Configuration
Software ICP100.
Since the digital outputs are "passive" the process of external elements always requires an external current supply. In
case of larger loads this should be independent of the module supply. At the connection of inductive loads a connection
with a free wheeling diode is recommended in order to prevent possible disturbances by e.g. induced voltage.

To the digital outputs you can connect directly: signal lamps, small relays, switching relays for larger loads, acoustic
signal installations, buzzer respectively beeper etc., as long as the connected loads are not exceeding the values
described in the technical specifications chapter 11.
3.11. Several Sensors at one Module
The
Datalogger
IDL 101
can take up and process sensor signals from several heterogeneous sensors simultaneously. As
many sensors can be connected as there are analog and digital signal inputs and outputs available. At the
Datalogger
IDL 101 this means the maximum of 22 sensors, 6 analog and 16 digital sensors.
3.12. Module Jack
ICM 100
The
Intelligent Sensor Modules ISM of the series "100" have connection potential on the left and on the right side. Via
these the bus and the power supply can be led from one module to the next by means of the Module Jacks
ICM 100.
This type of bus connection and of power supply is particularly advantageous if several modules are mounted on one
common profile rail side by side. In this case the connection via the terminals can be dropped, except for one module.
It is also possible to connect different modules of the line "100" via Module Jacks (e.g.
ISM 111 with ISM 111, ISM 112
and
IDL 100)
