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 5 = terminals 2, 3 and 6
F-DI 6 = terminals 4, 5 and 7
Max. connectable cross-section: 1.5 mm²
Type: Screw terminal 1 (see Chapter "Control cabinet installation and EMC / connection system")
1) DI: Digital input; M1: Ground reference
2) Pure hardware delay
NOTICE
For the digital inputs DIx+ to function, the particular reference potential must be connected
to input DIx.
This is achieved by:
1) Routing the ground reference of the digital inputs as well, or
2) A jumper between DIx and terminal M1.
