6ES5430-4UA13 | Siemens | SIMATIC S5 24VDC Digital Input

Product Description

High-Density Digital Signal Acquisition for SIMATIC S5

The Siemens 6ES5430-4UA13 is a high-density digital input module engineered for the legacy SIMATIC S5 automation platform. Specifically designed as part of the 430 series, this module provides 32 discrete input channels in a "Compact Version U" form factor. It is utilized to capture binary signals from field devices such as limit switches, photoelectric sensors, and relay contacts, converting them into logical states for the PLC processor. The 6ES5430-4UA13 features a floating (isolated) circuit design, which enhances system reliability by preventing ground loops and protecting the internal PLC backplane from external electrical interference.

Robust Performance for Legacy Infrastructure

As a critical component for maintaining existing industrial infrastructure, the 6ES5430-4UA13 operates on a standard 24 VDC signal level. It is optimized for high-speed logic execution with a typical response time of 4 ms, ensuring accurate state detection for fast-moving industrial processes. While the SIMATIC S5 series has reached the end of its active product lifecycle, this module remains an indispensable spare part for facilities in the automotive, chemical, and manufacturing sectors that continue to rely on the proven durability of S5 hardware. Its rugged German engineering ensures stable operation within a wide temperature range, extending the service life of mission-critical control cabinets.
