Siemens 6ES7138-4FB04-0AB0 is a PROFIsafe digital output module for the SIMATIC ET200S distributed I/O system. It provides four fail-safe digital outputs (F-DO) with transistor switching that operate at 24 V DC, with a lamp-load maximum of 10 W and a total module current capability of 2 A. The 30 mm-wide module supports safety levels up to PL E (ISO 13849), SIL3 (IEC 61508), and Category 4 (EN 954-1) and can be used in PROFINET configurations with compatible controllers. This device enables safe, reliable actuation in safety-critical automation applications within ET 200S installations.
