Wiring longer than 30m must be screened.
Note the correct polarity of the supply voltage!
Digital inputs
The UMG 512 has two digital inputs. An input signal
is detected on a digital input if a voltage of at least 18V
and maximum 28V DC (typically at 4mA) is applied. There
is no input signal for a voltage of 0 to 5V and a current
less than 0.5 mA.
