Product Overview

The 6ES7521-1FH00-0AA0 is a SIMATIC S7-1500 digital input module (SM 521 family) providing 16 AC input channels (230 V / 120 V AC, 50/60 Hz) arranged in groups of four. It is designed for integration into Siemens S7-1500 automation systems and communicates via the standard backplane bus. Typical uses include AC mains-level status monitoring, process control signal interfacing, and distributed input module deployment in manufacturing and infrastructure control systems. The module supports I&M data, prioritized startup, and is configurable via TIA Portal from version V12.
