2.7 DIGITAL I/O (-12 MODELS)
2.7.1 Input
There is one optocoupled polarity insensitive input available on the Processor units with the
I/O option. See par. 2.3.7 for pinout.
“Polarity Insensitive” means that, in the applications examples shown below, the user can
exchange I1A with I1B without affecting the system behaviour.
The user can handle the input through specific commands (see par. 2.7.3 for the specific
Command Protocol Reference Manual according to your processor unit model).
The electrical features of the input are:
Maximum voltage: 30 Vdc
Minimum voltage: 6 Vdc
Maximum current: 28 mA
The input is optocoupled and can be driven by both an NPN and PNP type command.
