Figure 3.4 Connection of the data logger to the bus by a stub cable
3.8 Sensor Connection
The analogue 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 are de-
scribed in chapter 5. The respectively valid pin assignment is
determined by means of the configuration software.
Since the digital outputs are "passive" the processing of extern-
al elements always requires an external current supply. In case
of larger loads this should be independent of the data logger
supply.
At the connection of inductive loads a connection with a diode
is required in order to prevent possible damages by induced
voltage.
