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.

- 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.
