Product Overview

The Siemens part 6ES7138-4FA03-0AB0 is a fail-safe electronics module designed for the SIMATIC ET 200S distributed I/O platform. It provides four fail-safe digital inputs (F-DI) at 24 V DC and interfaces with safety-oriented systems via PROFIsafe. In a control system, it serves to capture safety-critical input signals and transfer them to a safety CPU or controller. Typical industrial uses include functional safety monitoring in machinery, emergency stop circuits, and safety interlock logic within standardized SIL 3 / PLe environments.
