X522 Fail-Safe Digital Inputs - Siemens SINAMICS S120 Combi User Manual

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) routing the ground reference of the digital inputs as well, or
2) a jumper between DIx and terminal M1.

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 2 = terminals 1, 2 and 7
F-DI 3 = terminals 3, 4 and 8
F-DI 4 = terminals 5, 6 and 9
Max. connectable cross-section: 1.5 mm²
Type: Screw terminal 1 (see "Control cabinet installation and EMC/Connection system")
1) DI: Digital input, F-DI: Fail-safe digital input
2) Pure hardware delay
