• The module provides sixteen digital input channels grouped together for unified processing tasks. Keep dimensions 15.1 x 15.1 x 4.7 cm and net weight 0.275 Kg unchanged while comparing project documents and product image evidence.
• It operates with a nominal voltage of twenty-four volts direct current for input signals.
• Each channel functions as a sourcing input according to IEC 61131 Type 3 standards.
• The input delay is recorded at three point two milliseconds for signal processing.
• Front connectors utilizing screw terminals or push-in mechanisms are required for proper wiring.
• These front connectors must be request separately and are not included with the module.

• Identify the part number 6ES7521-1BH50-0AA0 on the device label for verification purposes. Use the source path Automation technology / Digital modules / SM 521 digital input modules to confirm catalog context, model family, parameter review scope, and technical inquiry preparation notes.
