The 6ES7 521-1BL00-0AA0 is a digital input module from the SIMATIC S7‑1500 series, designed to 

reliably acquire 24 V DC digital signals from field devices — such as proximity sensors, switches, or 

status contacts — and feed them into the PLC system. It provides a high‑channel‑count input interface 

organized in groups, allowing efficient consolidation of multiple discrete signals in compact form.
