Product Description

The SIMATIC S7 Interface Module 6ES7902-3AC00-0AA0 is a robust ET 200 communication module designed for seamless integration within industrial automation systems. It serves as a critical link between the SIMATIC S7-300/400 PLCs and distributed I/O devices via the 6ES7902 adapter cable, enabling reliable data transmission over PROFIBUS DP networks. This module operates within a voltage range of 19.2–28.8 V DC and functions optimally in temperatures from -20°C to +60°C, ensuring stability in harsh environments. With support for connecting up to 32 nodes and a maximum transmission rate of 12 Mbps, it streamlines communication in manufacturing, process control, and machinery applications. Its key advantages include rugged construction, plug-and-play compatibility, and immunity to electromagnetic interference, while limitations include dependency on external configuration tools. The module lacks onboard I/O but interfaces directly with ET 200 submodules for scalable expansion.
