Product Description

The 6ES5231-1AA31 SIMATIC S5 PLC module is an analog input module designed for industrial automation systems. It provides 16 single-ended analog input channels, supporting voltage or current signals (e.g., ±10 V, 4–20 mA) with configurable resolution up to 13 bits. Operating within 24 V DC power (±10% tolerance) and a temperature range of 0–60°C, it integrates seamlessly into SIMATIC S5 racks via backplane communication. This module features high noise immunity and galvanic isolation between channels, making it ideal for process control, manufacturing, and machinery applications. While lacking built-in display or battery, its robust construction ensures reliability in harsh environments. Limitations include compatibility only with legacy S5 systems and no native support for modern fieldbus protocols. The 6ES5231-1AA31 excels in precise signal acquisition for analog sensors in automation setups.
