8. Digital inputs and outputs
8. 1 Digital inputs
The device has 2 digital inputs to which you
can connect one signal generator each.
An input signal is detected on a digital input
if a voltage of at least 10 V and maximum
28 V DC is applied.
The fl owing current is at least 1 mA and
a maximum of 6 mA.
Pay attention to the supply voltage's polarity!

CAUTION!
Transmission errors and
damage to property due
to electrical faults
If the line is longer than 30 m, there is
an increased probability of transmission
errors and damage to the device due
to atmospheric discharge.
Use a shielded cable for connection
to the digital inputs.
