More Information

Overview Manuals Applications Environmental Ratings Safety & Compliance Integration

Features:

  • Accepts sixteen 115–240 V AC status circuits directly at the S5 rack.
  • Maintains two isolated eight-channel groups for high-voltage field organisation.
  • Filters normal mains-related transitions with defined ON and OFF delays.
This order number is the high-voltage member of the S5 436 AC input family.

It eliminates separate interposing relays where high-voltage auxiliary contacts can be read directly.

Cabinet segregation, diversity and terminal safety are central to selection because the module carries mains potential at its connector.

Apter Power can review sourcing, documentation and system matching for 6ES5436-4UA11.
Verified resources for Siemens 6ES5436-4UA11: Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Power distribution panels report breaker and contactor auxiliary states at 115 or 230 V AC.
  • Large machines collect long-distance interlock contacts without converting each signal to 24 V DC.
  • Legacy plant systems retain their established high-voltage control philosophy while servicing the S5 input stage.
  • Full channel use is supported with the documented forced-ventilation arrangement.
  • Without a fan, only 75 percent diversity is permitted at the 240 V upper rating.
  • At 35 °C or 115 V AC, the documentation permits full diversity without forced cooling.
  • Field terminals carry hazardous AC voltage and require appropriate barriers and insulation.
  • The two isolated groups must preserve separation from each other and from low-voltage circuits.
  • Protective devices and safe-access procedures remain mandatory even when the controller is stopped.
  • The 40 mm module occupies the documented SIMATIC S5 rack slot.
  • Field circuits use the matching front connector and group-common arrangement.
  • Cable lengths may reach 600 m unshielded or 1000 m shielded when installation conditions are satisfied.
Description
6ES5436-4UA11 brings sixteen 115–240 V AC states into an S5 controller without intermediate low-voltage relays. Typical input current is approximately 15 mA at 115 V and 25 mA at 240 V.

The module evaluates field transitions up to 20 Hz with separate rise and fall delays that reject short mains disturbances. Two isolated groups allow the cabinet to organise independent high-voltage circuits.

At 240 V AC, no-fan diversity is limited and creepage, conductor insulation and terminal barriers require particular attention. The replacement must retain the original group commons and protective isolation from low-voltage wiring.

Technical notes
Treat all terminals of 6ES5436-4UA11 as hazardous mains circuits and maintain the required separation before accessing the front connector.
