ProData II
Digital inputs
The ProData 2 features 15 digital inputs, which are
subdivided into three groups of 5 inputs, each with
a joint earth.
The status of each of the inputs is shown by
the corresponding LED. The corresponding LED
illuminates green if there is a signal on this interface.
An input signal is recognised (signal “1”) if a voltage of at
least 18 V is applied (typically 4 mA at 24 V). If the voltage
is lower than 5 V DC, no input signal exists (signal "0").
Wiring longer than 30 m must be screened.
Correct polarity of the supply voltage (20 ... 30 V DC)
must be ensured!
