Pin 4 (analogue output)
The switching output 1 / analogue output can be used as switching output or analogue current output (4-
20 mA) / analogue voltage output (0-10 V).
The analogue current output offers more transmission reliability than the analogue voltage output. The
analogue current output is independent of the cable length and ensures better signal quality towards the
industrial controller.
In the industrial controller the analogue current is converted into analogue voltage via a load resistor
against GND. The load resistor is selected according to the indications in the data sheet. High-resistance
load resistors are to be preferred over low-resistance load resistors due to the lower heat development in
the device.

Using the ifm Vision Assistant software it is possible to assign one process value each to the start value
(4 mA / 0 V) and the end value (20 mA / 10 V) of the analogue output.

Pin 7 / 8 (switching inputs)
The switching inputs provide the following functions:
●
The different parameter settings of the functions are indicated in the software manual.
The electrical data of the switching outputs 1 and 2 is indicated in the data sheet of the sensor.
