16 logic inputs (Vlog)
To open all the parameters of a digital input, press the symbol
from the measure colomn :
The logic inputs can monitor all signals up to 24V. To increase the maximum permissible voltage,
the Logic channel box option 917008000 is available.
ò
The switchover threshold is between 1,2V and 2,8V.

. Note that Frequency, Counter and PWM measurands will be available in a later version. You can also
activate measurements from the table
thanks to the button
from the
Mesurand colomn.
By pressing the icon shown below, you can duplicate all the parameters of the selected logic input

Power Supply Outputs
The external power supply located on the 25-pin D-Sub connector provides a nominal voltage of 12V +/- 5% with
a maximum delivered current of 200 mA (limited by resettable fuse).
For example, the power supply can be used to power a sensor.
