Product description

The Siemens SIPLUS S7-1500 CPU 1516F-3 PN (6AG2516-3FP03-4AB0) is a robust, rail-based central processing unit designed for fail-safe applications in harsh environmental conditions. Featuring conformal coating for protection against moisture and corrosive substances, it operates reliably in extreme temperatures from -40°C to +70°C (OT4) and up to 85°C (ST1/2 for 10 minutes). This CPU boasts 3 MB of work memory for programs and 7.5 MB for data, with a fast bit performance of 6 ns.

Equipped with three interfaces: PROFINET IRT (2-port switch), PROFINET RT, and PROFIBUS, this CPU is ideal for complex networking requirements in industries like chemical, oil & gas, and heavy manufacturing. It supports safety functions up to SIL 3 and PLe, making it suitable for safety-critical applications requiring high availability and precise control.
