Siemens AS-I Line Accessory for Micro Automation Set 3RX9020-0AA00

Siemens 3RX9020-0AA00 AS-I Line accessory is an essential component designed for use with Micro Automation Sets to facilitate efficient power supply and data communication over a simple two-wire network. It provides a reliable interface for connecting inductive sensors, switching valves, and other discrete components to controlling devices such as PLCs or PCs.

The product features a uniquely designed two-core cable with a trapezoidal cross-section that prevents polarity reversal. This cable supplies 30Vdc power to sensors via the yellow core, while the black core can be used for 24Vdc actuators. The system supports network lengths up to 100 meters, expandable to 300 meters with repeaters, thereby allowing extensive and flexible automation system layouts.

By combining power and data lines, this accessory significantly reduces cable requirements and installation time, enabling cost-effective automation solutions. The AS-I connection modules allow users to connect standard sensors and actuators with all the advantages of addressability, increasing potential I/O nodes up to 124 inputs and outputs on a single AS-I network.

The communication protocol is designed for high data accuracy and robust error detection even in electrically noisy industrial environments, making it ideal for manufacturing, process automation, and other industrial applications. Additionally, the accessory supports hazardous area certifications such as ATEX and EAC, expanding its usability in specialized environments.

Installation is straightforward, with features that promote fast commissioning, easy maintenance, and user-friendly diagnostics. The AS-I Line accessory can be used either as a host or in standalone configurations and is compatible with various fieldbus systems, enabling integration into comprehensive automation networks.
