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.
Description
6ES5435-4UA11 accepts sixteen AC input signals at 47–63 Hz and isolates them in two groups of eight. Typical channel current rises from about 15 mA at 48 V AC to 20 mA at 60 V AC.

The input network detects contact or sensor states with a typical five-millisecond rising response and twenty-millisecond falling response. A maximum input frequency of 20 Hz suits conventional interlocks rather than high-speed counting.

Cabinet ventilation affects the permitted channel loading at the upper voltage limit. Existing group commons, field protection and cable lengths must therefore be checked before moving conductors to the replacement module.

Technical notes
Observe the documented diversity limits for 6ES5435-4UA11 when operating many channels near 60 V AC without forced ventilation.
