Outputs and Inputs 69-
5.5 I/O pins (only for CT 4M)
The CT 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:
Function
I/O pin acts as
Description
Alarm
Output digital
Open collector output/ definition as High- or Low alarm via norm. open/
norm. 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)
Emissivity external
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 a uncommitted value
Laser on Low
Input digital
Turning on the laser (Low signal)
Laser on 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
Radiation
Input analog
The transmitted ambient temperature will be determined by a voltage on
the I/O-pin [0–10 V; range scalable].
