Siemens 6ES7143-3BH10-0XA0 Programmable Logic Controller Module

Siemens 6ES7143-3BH10-0XA0 is a SIMATIC DP, BASIC MODULE BM143 for the ET 200eco distributed I/O system, delivering eight digital inputs and eight digital outputs in a compact 60 × 210 × 28 mm package. The module operates on 24 V DC, with input supply current up to 70 mA and load-side current up to 60 mA, and each of the eight outputs can source up to 1 A with a total summation current limited to 1 A at temperatures up to 55 °C. It uses eight M12 connectors for DI/DO connections and carries IP65/67 protection, enabling mounting in harsh industrial environments. A duplicate-addressing option and a separate connection block (6ES7194-3AA00-0) are supported to tailor wiring and field connections, reflecting its role within the ET 200eco DP network. The BM143 module is designed for 24 V DC logic and is commonly used to interface sensors and actuators, supporting straightforward integration into Siemens automation projects that require reliable, distributed I/O across compact footprints. Weighing around 210 g, it fits within DIN-rail configurations typical of ET 200eco installations, offering a rugged, field-configuration-friendly solution for compact, high-density I/O needs in automation control systems.
