Product Description

The Siemens 6ES7902-3AB00 Interface, also known as the SIMATIC S7 Bus Connector 6ES7902-3AB00-0AA0 Module, is a high-performance interface designed for industrial automation systems. It facilitates seamless integration with SIMATIC S7-300/400 PLCs, supporting up to 32 directly connected modules via the RS485 interface. This bus connector operates within a voltage range of 20.4–28.8 V DC and functions optimally in ambient temperatures of 0–60°C. Ideal for manufacturing, process control, and machinery industries, it ensures reliable communication across distributed systems with minimal signal interference. Key advantages include rugged construction, plug-and-play compatibility, and support for PROFIBUS DP protocols. However, it lacks native support for newer communication standards like PROFINET. The module does not include internal batteries, screens, or proximity sensing capabilities. Its compact design and robust connectivity make it a staple in automation networks requiring stable data exchange.
