Siemens 6ES5430-2BA11 Electronic Module

This Siemens electronic module provides reliable digital input processing for S5 systems. The Siemens 6ES5430-2BA11 handles up to 16 digital input channels simultaneously. Its robust design ensures dependable operation in industrial environments. This module interfaces directly with field sensors and switches. The Siemens 6ES5430-2BA11 supports flexible input voltage configurations.

Physical Dimensions and Mounting Specifications

The module measures 232 mm in height and 25 mm in width. Its overall depth reaches 160 mm including the front connector. This unit weighs approximately 0.48 kilograms for stable rack installation. The housing supports standard 35 mm DIN rail mounting in S5 racks. The Siemens 6ES5430-2BA11 features a 20-pin front connector for all signal wiring. This connector accepts conductor cross-sections from 0.5 mm² to 2.5 mm².

Input Specifications and Electrical Characteristics

This module accepts input voltages from 24 V DC to 48 V DC for flexibility. Each input channel provides a nominal current draw of 10 mA at 24 V DC. The input impedance measures approximately 4.7 kΩ for each channel. Input delay time reaches about 3 milliseconds for fast signal detection. The Siemens 6ES5430-2BA11 draws a typical current of 80 mA from the backplane supply. A built-in 10 µF filter capacitor suppresses transient noise. LED indicators display the status of each input channel individually.

Isolation and Diagnostic Features

Optocoupler isolation separates the logic circuits from the input field wiring. This isolation withstands 500 V AC between the backplane and input circuits. A common status LED indicates the module’s operational condition. The Siemens 6ES5430-2BA11 includes short-circuit protection for all input channels. Reverse polarity protection prevents damage from incorrect wiring connections. The module offers a voltage range tolerance of ±20% for reliable operation.
