I/O Pins

The CT 4M has three I/O pins, which can be programmed as output or input using the software. The following
functions are possible:
Function
Alarm
Valid Low
Valid High
Hold Low-High
Hold High-Low
Hold Reset Low
Hold Reset High
External Emissivity
Uncommitted value
Laser on Low
Laser off High
External
Ambient compensation
External Transmitted

Low/High level: Via Software
I/O Pin is on Description
Output (digital) Open collector output/ definition as High- or Low alarm via normally open/
normally 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 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].
