The inputs can be easily controlled with a simple switch or relay contact. The
corresponding input is connected to common ground. An open input is recognized
as “high” due to the internal pull-up resistor. Ground potential equals “low.”
The input circuit also allows the control via connected potential in the following
ranges:
Input voltage 30 V DC max.; min – 30 V DC
Level
High = + 2.6 V to + 30 V or open
Low = - 30 V to + 2.3 V
