Features:
- 32 floating digital inputs accept grouped 24 VDC field signals.
- The compact 432 input function fits SIMATIC S5 rack assemblies.
- Field wiring can be arranged with shielded cable and filtered load supply.
The current configuration is a compact SIMATIC S5 digital input assembly with 32 floating channels for 24 VDC field contacts.
It captures discrete field states for controller logic in legacy S5 control cabinets and supports grouped status monitoring at the rack interface.
Check the rack position, signal grouping, front wiring and supply filtering before installation so the module matches the existing S5 assembly.
Availability depends on Siemens lifecycle status and Apter Power sourcing confirmation.

- Discrete 24 VDC status acquisition from field contacts in SIMATIC S5 control cabinets.
- Grouped input monitoring in S5-135U and S5-155U rack assemblies.
- Legacy S5 replacement projects that retain floating digital input wiring.
- The 432 input function is intended for compact SIMATIC S5 rack assemblies with grouped field returns.
- Four isolated input groups let separate field circuits remain distinct at the rack interface.
- Two-wire BERO devices can use the module supply arrangement without changing the input role.
- Set the front selector for the required input delay before commissioning the card.
- Keep the S5 front-connector wiring aligned with the selected rack position and channel grouping.
- Use the documented signal-cable and 24 V load-supply practices when extending field wiring.
- The input groups are tested for the required VDE 0160 isolation between groups and earth.
- The 24 V input interface accepts the documented logic window without requiring a separate signal conditioner.
- Cover unused rack positions so the installed assembly retains its specified IP20 protection.
