Product Details

• Part Number 1 6ES7231-0HC21-0XA0

Product Description

Siemens designates 6ES7231-0HC21-0XA0 as an Analog Input Module associated with the Simatic S7 control platform.

In day-to-day system operation, digital input hardware creates the path from field-level status signals to control logic, allowing the system to evaluate operating conditions and respond through configured sequences or protective actions. The surrounding rack and module arrangement should be reviewed before installation.

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.

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.
