An F-DI consists of 1 digital input and a 2nd digital input where, in addition, the cathode of the optocoupler is fed-out.
F-DI 7 = terminals 1, 2 and 7
F-DI 8 = terminals 3, 4 and 8
F-DI 9 = terminals 5, 6 and 9
Type: Screw terminal 1 (Page 321)
DI: Digital input, F-DI: Fail-safe digital input

Note
Execution of a test stop
The test stop of the F-DI 5 to F-DI 9 can only be performed if the F-DI is supplied from L2+.
Note
Ensuring the function of digital inputs
For the digital inputs DIx+ to function, the reference potential must be connected to input DIx-
in each case.
This is achieved by using one of the following measures:
1. Providing the ground reference of the digital inputs
2. A jumper between DIx- and terminal M1
