Switching output
Switching outputs Q1 and Q2 show the distance information as logical switching information. They sig-
nalise whether the preset hysteresis switching range is exceeded or fallen short of.
Thus, they are ideally suitable for direct further processing of monitored values such as fill level or ob-
ject detection. Parameterisation is done via the serial interface.
A load resistor of > 150 Ohms/ 6 W (max. operating voltage of 30 V; max. load current of 0.2 A) must be
switched against VDC- (GND of supply voltage) at the switching output. It is important that the load cur-
rent of 0.2 A is not exceeded.
Typical resistance: 1 kOhm against VDC-
(
not
against GND)!
Q1/Q2 parameterises the behaviour of the switching outputs.
The parameters include the beginning w of the measuring range when the output switches, the length x
of the measuring range, the hysteresis y as well as the logic behaviour z.
