Features:
- 32 floating digital inputs with a 24 V DC nominal field supply.
- Compact U-format module for S5-135U and S5-155U PLC assemblies.
- Defined input thresholds and response behavior for discrete signal acquisition.
The 4UA13 configuration is the floating 430 input card for a compact S5 rack, presenting a full 32-point group to the controller through one module position.
It turns field contact and sensor changes into digital states for the PLC, with the published threshold window and input timing suited to conventional 24 V DC instrumentation.
Check the target PLC family, adaptor requirement and field-cable route before commissioning. An S5-115U installation needs the specified adaptor arrangement, while S5-135U and S5-155U systems use the module in their native rack context.
The 6ES5430-4UA13 is documented by the manufacturer (OEM).

- S5-135U and S5-155U PLC racks collecting 24 V DC discrete field states.
- S5-115U retrofit work using the specified adaptor casing.
- Machine sequences that require floating contact and sensor inputs.
- The 430-4 function is used with SIMATIC S5 compact racks that expect thirty-two 24 V DC inputs.
- Its isolated input group suits field contacts that share the module voltage class but require a common group reference.
- The 430 designation should be matched to the same rack slot and front connector before exchange.
- Verify the polarity and terminal assignment at the front connector before applying the 24 V DC supply.
- Keep the field cable route within the allowed unshielded or shielded length for the selected delay.
- The compact U-format card should be seated fully in the S5 rack guide before the retaining hardware is tightened.
- The input state is represented in the S5 process image as a discrete signal, not as an analog value.
- The enable input gives the cabinet a defined way to inhibit the input section during maintenance.
- Input response timing should be checked with the existing contact and sensor circuits after replacement.
