Internal electrical scheme of the option Analog Input 2
The integrator has the responsibility to protect the input from electric disturbances and to
respect the values of the functioning parameters.
8.2.4.5 Input/Output (0
– 3.3 V) direct on INPUT2, INPUT3
As an option on the GenLoc 41e, it is possible to have 3.3V input directly connected to the ARM. (Contact
us).
These Input/Output INPUT2, INPUT3 are directly connected on the ARM : INPUT2 on Port
PA1 and INPUT3 on port PA2.
The selection of the direction (Input/Output) is done by software.
