I/O pins (only for 4M Models)

The 4M has three digital pins which can be programmed as outputs (digital) or as inputs (digital or analog) using the CompactPlus Connect
software. The following functions are available::

I/O Pin ist ein Beschreibung
Output digital Open collector output/ definition as High- or Low alarm via norm. open/ norm. close options
in software dialog.
Input digital The output follows the object temperature as long as there is a Low level at the I/O pin.
After discontinuation of the Low level the last value will be held.
Input digital The output follows the object temperature as long as there is a High level at the I/O pin.
After discontinuation of the High level the last value will be held.
Input digital The last value will be held if there is a signal with a rising edge on the I/O pin.
Input digital The last value will be held if there is a signal with a falling edge on the I/O pin.
Input digital Reset of Peak or valley hold (High-Low signal)
Input digital Reset of Peak or valley hold (Low-High signal)
Input analog The emissivity value can be adjusted via a 0-10 V signal on the I/O pin (scaling possible via
software).
Input analog Display of a uncommitted value
Input digital Turning on the laser (Low signal)
Input digital Turning on the laser (High signal)
Input analog The ambient temperature will be determined by a voltage on the I/O-pin [0–10 V; range
scalable].
Input analog The transmitted ambient temperature will be determined by a voltage on the I/O-pin [0–10
V; range scalable].
