CT 71-
3.3. 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
I/O Pin is on
Description
Alarm
Output (digital)
Open collector output/ definition as High- or Low alarm via normally open/
normally close options in software dialog.
Valid Low
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.
Valid High
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.
Hold Low-High
Input (digital)
The last value will be held if there is a signal with a rising edge on the I/O pin.
Hold High-Low
Input (digital)
The last value will be held if there is a signal with a falling edge on the I/O pin.
Hold Reset Low
Input (digital)
Reset of Peak or valley hold (High-Low signal)
Hold Reset High
Input (digital)
Reset of Peak or valley hold (Low-High signal)
External Emissivity
Input (analog)
The emissivity value can be adjusted via a 0-10 V signal on the I/O pin (scaling
possible via software).
Uncommitted value
Input (analog)
Display of uncommitted value
Laser on Low
Input (digital)
Turning on the laser (Low signal)
Laser off High
Input (digital)
Turning on the laser (High signal)
External
Ambient compensation
Input (analog)
The ambient temperature will be determined by a voltage on the I/O-pin [0–10 V;
range scalable].
External Transmitted
compensation
Input (analog)
The transmitted ambient temperature will be determined by a voltage on the I/O-
pin [0–10 V; range scalable].
Low/High level: Via Software
