Product Description

The Siemens 6ES7421-1BL00-0AA0 is a Digital Input Module used with the Simatic S7 automation platform.

In day-to-day system operation, a digital input module receives discrete on/off states from field contacts and devices, then makes those states available to the controller for monitoring, sequencing, alarms, and interlocks. Exact operating details should be taken from the installed model documentation.

SIMATIC S7 integrates programmable control, modular I/O, and industrial communication functions. This product belongs to the PLC modules layer of the installed S7 automation solution. System drawings should be consulted before replacement.

Country of origin is listed as Germany.

For maintenance or replacement work, the exact module designation should be checked against the installed hardware, wiring records, and control-system documentation before the component is placed into service. The documented module assignment should remain the basis for selection.
