Siemens 6ES72211BF320XB0 Digital Input Module

Product Description

The SIEMENS 6ES72211BF320XB0 is a digital input module designed for use with Siemens S7-1200 series programmable logic controllers. It expands the discrete signal-reading capacity of a PLC system by accepting digital on/off signals from field devices such as sensors, switches, and pushbuttons. The module is compact and DIN-rail mountable, making it a standard component in industrial and building-automation control panels. Licensed automation technicians and controls engineers are the primary installers. At 0.375 pounds, the unit is lightweight and fits into tight panel layouts.

This digital input module is suited for light industrial, commercial building automation, and process control applications where additional discrete input points are required. It is typically installed alongside a Siemens S7-1200 CPU module in a control cabinet or enclosure. The module connects directly to the CPU base unit or to an expansion rail, allowing incremental growth of the I/O configuration without replacing the base controller.

Key Features

• Digital input functionality for discrete field signal monitoring
• Compact form factor at 4.134 inches x 3.543 inches x 2.283 inches
• Lightweight at 0.375 pounds for space-constrained panel installations
• Compatible with Siemens S7-1200 PLC platform expansion architecture
• Single-unit pack for straightforward procurement and inventory management

Compatibility

Designed as an OEM-style expansion module for Siemens S7-1200 series PLC systems requiring additional digital input capacity.

Installation Notes

Installation should be performed by a qualified automation technician or licensed electrician familiar with IEC and NEC low-voltage control wiring practices. De-energize the PLC system and disconnect all power sources before connecting or removing any I/O module. Follow the manufacturer documentation for module addressing and configuration within the TIA Portal programming environment. Verify that the control cabinet provides adequate grounding per applicable electrical codes before commissioning.
