Note
Operational functionality of DIx+ digital inputs
For the digital inputs DIx+ to function, the reference potential must be connected to input
DIx
- in each case.
•
Route the ground reference of the digital inputs.
•
Connect the DIx input and the M1 terminal via a jumper.

An F-DI comprises a digital input and a second digital input where, in addition, the cathode of the optocoupler is fed-out.
F-DI 2 = terminals 1, 2 and 7
F-DI 3 = terminals 3, 4 and 8
F-DI 4 = terminals 5, 6 and 9
