An F-DI comprises a digital input and a 2nd digital input where, in addition, the cathode of the optocoupler is fed-out.
F-DI 0 = terminals 2, 3 and 6
F-DI 1 = terminals 4, 5 and 7
Max. connectable cross-section: 1.5 mm²
Type: Screw terminal 1 (see Appendix A)
DI: digital input; M1: ground reference

Pure hardware delay

NOTICE
For the digital inputs DIx+ to function, the reference potential must be connected to input
DIx- in each case.
This is achieved by:
1. Providing the ground reference of the digital inputs, or
2. a jumper between DIx and terminal M1.
