Product Description

The **SIMATIC S7-400 module** **6ES7431-1KF00-0AB0**, part of the **Siemens SM431 16-channel** analog input series, is designed for high-precision industrial automation. This **16-channel analog** module supports voltage (±10V, ±5V), current (±20mA), and resistance inputs with 15-bit resolution, ensuring accurate signal processing. It integrates seamlessly into S7-400 racks, directly connecting up to 21 expansion modules via the backplane bus. Operating at 24V DC within a temperature range of 0–60°C, it excels in harsh environments such as process industries, manufacturing, and energy management. Key advantages include high noise immunity, galvanic isolation, and flexible configuration via STEP 7 software. A minor drawback is its reliance on centralized rack architecture, limiting remote deployment. Note: This module lacks built-in battery or display features.
