Overview
Siemens SIMATIC ET 200MP IM 155-5 PN HF (6ES7155-5AA00-0AC0) is a high-performance PROFINET IO device interface module designed for the ET 200MP distributed I/O system. It enables fast, reliable, and deterministic communication in demanding industrial automation environments.
This interface module supports up to 12 IO modules without a power supply and up to 30 IO modules with an additional power supply, making it highly scalable. With an integrated 2-port switch, RJ45 connectivity, and support for IRT, MRP, isochronous mode, and S2 redundancy, it is ideal for high-speed and mission-critical automation applications.
