The Siemens 6ES7521-1BL00-0AB0 digital input module is designed for use with the SIMATIC S7-1500 automation system, providing reliable signal processing for industrial production environments. This module features 32 digital inputs for 24 V DC, organized in two groups of 16 channels. Two of these inputs can also function as counters, offering enhanced flexibility for process monitoring. The module supports input delays ranging from 0.05 to 20 ms and uses input type 3 as specified in IEC 61131. Integrated diagnostics and hardware interrupts contribute to efficient troubleshooting and process control. The front connector (screw terminals or push-in) is not included and should be ordered separately.
