Switch output
The switch output is designed as an optoelectronic coupler or
a NAMUR contact (in accordance with DIN 19234).
— When the NAMUR contact is closed, the internal
resistance is approx. 1000 Ω.
— When the contact is open, the internal resistance is
> 10 kΩ.
The switch output can be changed over to "optoelectronic
coupler" if required.
— NAMUR with switching amplifier
— Switch output:
Ex d ia: Ui = 45 V
IMPORTANT
The power supply and the digital output must be either only
intrinsically safe or only non-intrinsically safe. A combination of
the two is not permitted.
Intrinsically safe circuits must have potential equalization in
place along the entire length of the cable of the circuit.
