Product Description: Siemens 6ES7138-4FA02-0AB0

The Siemens 6ES7138-4FA02-0AB0 is a failsafe digital output module for the SIMATIC ET 200S distributed I/O system, designed specifically for safety- related applications. This F-DO (Failsafe Digital Output) module provides 4 independent 24 V DC outputs, each capable of switching up to 2 A. It supports safety functions up to SIL 3 (IEC 61508) and PL e (EN ISO 13849-1), making it suitable for use in emergency stop circuits, safe actuator control, and safety interlock systems. This module is part of Siemens' Safety Integrated system and is certified for use in PROFIsafe environments via PROFIBUS or PROFINET with appropriate interface modules. It is used together with the ET 200S BaseUnits and configured through the TIA Portal or STEP 7.
