Features:
- Reads sixteen AC states over the 24–60 V range used by industrial control circuits.
- Separates the channels into two isolated groups for organised field potentials.
- Applies mains-frequency input filtering suited to contact and interlock monitoring.
The exact order number identifies the low-voltage AC execution of the S5 435 input family.
It translates grouped field conditions into binary states for the SIMATIC S5 process image.
Thermal diversity and group-common wiring must remain consistent with the original rack design.

- Legacy S5 panels use the module for contactors, selector switches and auxiliary contacts supplied from 24–60 V AC.
- Plant interlock circuits can separate two field groups while presenting sixteen states to the CPU.
- Long cable runs from remote switchgear remain practical within the documented shielded or unshielded limits.
- Full channel diversity is available with forced ventilation under the documented cabinet conditions.
- Without a fan, loading at the 60 V upper limit is reduced to 75 percent of the channels.
- At 35 °C or a 30 V field level, all channels may be used without forced ventilation.
- Two groups of eight require the correct field common and protective-device arrangement.
- The 40 mm module fits the designated S5 rack position and front-connector scheme.
- Unshielded routes can extend to 600 m and shielded routes to 1000 m within installation guidance.
- Input-state evaluation is intentionally limited to 20 Hz for stable AC contact acquisition.
- Different rising and falling delays suppress mains-related chatter while releasing an OFF state predictably.
- Unexpected intermediate states should be investigated for field voltage, contact resistance and common continuity.
