III. Differences from Modules of the Same Series

F3221/F322116: 16 DI, 2kV isolation, 10ms response

F3222: 16 DI, enhanced diagnosis, compatible with F3112/F3113A

F3223: 32 DI, two groups of 16 DI, 2kV isolation, most comprehensive diagnosis, power consumption doubled

IV. Alternative Suggestions

Direct replacement: No fully equivalent model available, 2 F322116 can be connected in parallel (32 DI, fully compatible)

Module replacement: F3DIO16/1601 (16 DI + 16 DO, SIL3, DIN rail)

System upgrade: HIMatrix F35 or HIMax (SILworX, modern communication, full series I/O)
