UMG 509
Wiring longer than 30m must be screened.
Note the correct polarity of the supply voltage!
Digital inputs
The UMG 509 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.
