DTU4x0 Interfaces and Wiring Diagrams
GPIO & Universal Inputs
DTU4x0 data loggers have 11 universal counting inputs for connecting a wide range of meters and sensors:
•
P1-P4
– independent GPIO lines
•
P5-P11
– universal counting inputs.
Inputs can be configured via the web interface of
cloud software as well as using
DTU
Configuration Tool
software. Types of devices available for connection to
P1-P11
inputs are given below:

Connecting meters
The following types of inputs can be configured to connect meters:
•
Counting/Pulse counter
–
the
type of input used when connecting pulse reed switch meters
to data logger, as well as meters with NAMUR output. The inputs are configured to connect
meters with polling frequency at outputs up to 100 Hz.
•
High-frequency meter (or HF pulse meter)
– the type of input used when connecting pulse
meters with an input polling frequency from 100 Hz and up to 5 kHz to data logger.
