Product Description:

The Siemens SIPLUS S7-1500 CPU 1516-3 PN/DP is a high-performance central processing unit designed for advanced automation systems requiring precision, speed, and environmental durability. Based on the standard SIMATIC S7-1500 CPU 1516-3 PN/DP (6ES7516-3AP03-0AB0), this SIPLUS version is equipped with conformal coating for reliable operation in harsh industrial environments with temperatures ranging from –40 °C to +60 °C.

The CPU features 2 MB of program memory and 7.5 MB of data memory, delivering strong performance for complex automation and motion control applications. With a 6 ns bit processing speed, it ensures fast, deterministic response times in time-critical processes.

Three integrated communication interfaces — PROFINET IRT with 2-port switch, PROFINET RT, and PROFIBUS — provide flexible connectivity for networked control systems and distributed I/O architectures. A SIMATIC Memory Card is required for program storage, firmware updates, and secure data handling.

This unit is ideal for mid- to large-scale automation tasks in manufacturing, energy, and process industries, where both performance and environmental resilience are essential.
