Siemens 6ES7138-4FB03-0AB0 Electronics Module

Siemens 6ES7138-4FB03-0AB0 SIMATIC DP Electronics Module for ET200S provides four PROFIsafe digital outputs (F-DO) for safe actuator control in distributed automation. It operates from a 24 V DC supply and delivers up to 2 A total load across its four outputs, all in a compact 30 mm-wide module that mounts into the ET200S base unit. As a DP electronics module, it communicates on PROFIBUS DP and can also be used in PROFINET configurations with IM 151-3 HF, enabling flexible integration in mixed networks. Safety ratings are certified up to Category 4 per EN 954-1, SIL3 per IEC 61508, and PL E per ISO 13849, aligning with safety-critical machinery applications such as safety interlocks, emergency stop circuits, and monitored safety outputs. The F-DO channels are isolated and designed to switch safety-critical loads with built-in diagnostic signaling back to the controller, supporting fast fault detection and reliable safety performance across the safety network. This spare-part module is compatible with ET200S system configurations, enabling scalable distributed safety implementations within existing SIMATIC DP architectures and ensuring consistent safety behavior across devices on the same network.
