Siemens 6ES7138-4FB04-0AB0 Electronics Module

Siemens 6ES7138-4FB04-0AB0 is a SIMATIC DP Electronics Module designed for the ET 200S distributed I/O system. It provides four PROFIsafe digital outputs (F-DO) to enable safe actuator signaling in safety-related automation tasks, and is intended as a DP electronics module for ET 200S. The unit operates from 24 V DC with a rated supply current of up to 2 A and comes in a compact 30 mm-wide form factor suitable for ET 200S mounting racks. It can be used in PROFINET configurations when paired with an appropriate IM module, such as IM 151-3 HF, expanding safe I/O integration in a PROFINET network. The safety capability supports up to PL E per ISO 13849 and up to SIL 3 per IEC 61508, reflecting its suitability for higher-integrity safety applications such as machine safety interlocks and safe stop circuits. This part is used as a spare/replacement module within the SIMATIC DP ET 200S family, offering a dedicated, four-Channel PROFIsafe output solution in a compact electronics module package.
