More Information

Overview Manuals Applications Configuration Safety Performance

Features:

  • 32 isolated digital input channels for 24 V DC field signals.
  • Compact U-format construction for a dense SIMATIC S5 430 rack position.
  • Discrete state acquisition for established S5 machine and process controls.
The 4UA14 order is the isolated 430 input version, giving a legacy rack one compact module with its full 32-channel input group.

It collects switch, contact and sensor states so the controller can evaluate machine permissives, interlocks and sequence conditions in discrete form.

Match the connector pinout, field reference and rack position before fitting a spare; the Siemens article is deleted without replacement, so migration risk should be assessed at the same time.

The 6ES5430-4UA14 is documented by the manufacturer (OEM).
Verified resources for Siemens 6ES5430-4UA14: 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.
  • Legacy SIMATIC S5 racks that need 32 isolated 24 V DC input points.
  • Machine interlock circuits built from discrete switches and contacts.
  • Retrofit projects preserving an established 430-series input station.
  • The 430 input image uses the module channel order defined by the existing S5 rack configuration.
  • The U-format wiring must leave terminal 3 unused where the manual specifies that the L+ connection is not required.
  • Select the installed delay and BERO arrangement from the project wiring rather than from a generic 430 card setting.
  • The input group is isolated from the rack field wiring within the documented 24 V DC voltage class.
  • Keep the connector de-energized while checking the polarity-reversal allowance and signal returns.
  • Use the specified VDE group-to-earth test arrangement when validating a serviced rack.
  • The input stage is designed for stable discrete sensing of switches, contacts, and comparable 24 V DC devices.
  • Its lower backplane current demand is suited to compact S5 assemblies with limited internal supply margin.
  • The 430-4 response behavior should be evaluated against the controller scan and the connected field-contact timing.
Description
Siemens 6ES5430-4UA14 is a compact SIMATIC S5 430 input assembly for collecting discrete 24 V DC field states in a legacy control rack. Its 32 isolated channels give an existing S5 station a dense point count without expanding the module footprint.

The U-format arrangement concentrates the field interface at one rack position and suits switch, contact and sensor signals that must be represented as digital states in the controller. This makes the module useful for maintaining established machine sequences and interlock circuits.

Before installation, compare the connector wiring, input grouping and supply polarity with the rack drawing. Siemens lists this article as deleted without replacement, so migration planning and a like-for-like spare check should be completed before the existing card is removed.

Technical notes
Confirm the 24 V DC potential grouping and the deleted-without-replacement status before removing an installed 430 input module.
