6.1.3 Functional modules

The functional modules can be classified according to their assignments:
Electrical and temperature signals measurement
■
Pressure measurement, (2 different modules, up to 4 internal pressure sensors and 2 connectors for external pressure
EN
■
sensor)
Electrical and temperature signals generation/simulation
■
Pressure generation and regulation
■
Environmental parameters measurement
■
Many different configurations are available according to the specific requirements of the user.

6.1.3.1 Input module for electrical/temperature signals

The input module for electrical/temperature parameters measurement is one of those modules inserted from the instrument's
front panel; two slides drive the module into its position. It is possible to have up to two input modules in the same instrument:
IN A and IN B. This terminology is used also by the software to carry out the connection between physical input IN and
software channel.
For example:
If you connect a resistance thermometer Pt100 to module IN A, the temperature measured by this resistance thermometer can
be displayed in any of the four software channels available.
The following figure shows the pins connection in electrical/temperature IN module.

6.1.3.2 Output module for electrical/temperature signals

The output module for electrical/temperature parameters generation or simulation is one of those inserted from the
instrument's front panel; two slides drive the module into its position. It is possible to have up to two output modules in the
same instrument: OUT A and OUT B. This terminology is used also by the software to carry out the connection between
physical output OUT and software channel.
For example:
If you connect a signal receiver to module output OUT A, the current 4 ... 20 mA generated can be displayed in any of the four
available windows.
The following figure shows the output module for electrical/temperature parameters.
The 2 INPUT cards and 2 OUTPUT cards are plug and play modules and can be installed by the user himself.
