10.10 Inputs and Outputs (Main Modules 1 & 2)
I/O functionality is a powerful tool of the M3x5 Quality Analyser. Using various I/O modules
the device can be used not only for monitoring main electrical quantities but also for
monitoring process quantities (temp., pressure, wind speed…) and for various control
purposes.
The module settings displayed will depend on the I/O modules built in to the instrument or
defined in the settings file if working off-line.
PLEASE NOTE
All modules have double input or output functionality, except the Watchdog output module.
All modules with a double input or output are represented as two separate modules in
QDSP2.
10.10.1 Analogue output module
The analogue output module is useful for control and measurement visualisation purposes. It
can be connected to analogue meters, PLC controller, etc. It has the defined output range of
20mA DC. Output parameter and shape (up to 5 break points) of an analogue output can be
configured using the
QDSP2 software.
10.10.1.1 Output parameter
Output parameter can be any measured value that is required for monitoring, recording,
visualisation or control. The parameter is chosen from a drop-down menu.
10.10.1.2 Output range
The analogue output has a fixed range of 0 – 20mA.
10.10.1.3 Output Signal
This defines the actual range and output curve shape of the required analogue signal. Up to
5 break points can be programmed to achieve the required curve.
Output signal can be adjusted to meet all required purposes.

Shape of output signal (linear, Quadratic)

Number of break points for zoom function (up to 5)

Start and End output value
For improved visualisation of output signal parameters that have been set a graphical
representation of the transfer function is displayed.
