Siemens 6ES71314BD010AA0 4-channel Digital Input Module

Product Description

The SIEMENS 6ES71314BD010AA0 is a 4-channel digital input (4DI) module designed for use with Siemens S7-1200 series programmable logic controllers. It captures discrete on/off signals from field devices such as sensors, switches, and pushbuttons, converting them into digital data the PLC CPU can process. The module follows standard form-factor conventions for the S7-1200 platform and is installed by automation technicians and industrial controls specialists in panel-build and machine-control applications. Weighing 0.384 pounds and measuring 3.661 inches long by 3.031 inches wide by 2.598 inches tall, it fits neatly within standard control cabinet layouts.

This digital input module is suited for both light industrial and commercial automation environments where discrete signal acquisition is required. Typical applications include conveyor control, machine interlocking, process monitoring, and general-purpose PLC expansion. It is mounted directly to the S7-1200 CPU or existing signal module stack without additional hardware, making it a straightforward expansion option for controls professionals adding I/O capacity to an existing panel.

Compatibility

Designed as an OEM-style digital input expansion module for Siemens S7-1200 series programmable logic controller systems. No additional compatible model numbers were specified in the available product data.

Installation Notes

Installation should be performed by a qualified automation technician or licensed electrician familiar with PLC panel wiring practices and applicable electrical codes including the NEC. De-energize the PLC rack and disconnect all field wiring before removing or inserting signal modules. Secure the module to the DIN rail or CPU expansion port per the manufacturer installation guide before making field wiring connections. Do not hot-swap the module while the system is powered unless the CPU firmware and project configuration explicitly support that function.
