Technical Specifications and Hardware Overview

The Siemens 6ES5430-4UA13 functions as a digital input module for the SIMATIC S5 programmable logic controller system. This module measures 250 mm in height, 25 mm in width, and 185 mm in depth for standard rack mounting. It weighs approximately 0.75 kilograms, which enables straightforward handling during installation. The unit draws 0.25 A from a 5 V DC backplane power supply. It also requires an external 24 V DC supply for field input signal processing. The module provides 32 digital input channels for binary signal acquisition from field devices.

Each input channel operates at 24 V DC nominal voltage with a typical current of 7 mA. The unit includes integrated RC filtering circuits to suppress high-frequency noise. It offers an input delay time of approximately 3 ms for reliable signal detection. The module features optical isolation between the field inputs and internal logic. It contains no onboard memory for energy storage applications. The operating temperature range spans 0°C to 60°C for typical industrial environments. Storage temperatures extend from -40°C to 85°C without causing component damage. Humidity tolerance covers 5% to 95% non-condensing conditions for consistent performance.

Signal Acquisition and Processing Features

This module acquires digital signals from pushbuttons, limit switches, and proximity sensors. It buffers the input signals for the CPU through the system backplane. The Siemens 6ES5430-4UA13 supports both sink and source wiring configurations for field devices. It uses optocouplers to isolate the input channels from the logic circuitry. The unit provides a green LED indicator for each active input channel. It handles input voltages from -3 V to 30 V DC without damage. The module includes a removable terminal block for convenient field wiring connections. It operates without requiring any configuration or addressing DIP switches.

Installation and Compatibility Information

The 6ES5430-4UA13 mounts into any slot of the SIMATIC S5 rack system. It occupies one slot width for straightforward system integration. The module connects directly to 32 field devices through the front terminals. It remains compatible with all S5 CPUs for seamless operation. The unit employs a passive design with minimal power consumption. This module works alongside analog modules and communication processors. It provides reliable performance without requiring periodic recalibration or maintenance.
