Product Description: 6ES7138-4HA00-0AB0

The 6ES7138-4HA00-0AB0 is a failsafe digital output module for the SIMATIC ET 200S distributed I/O family. It provides eight electronically isolated 24 V DC outputs, each rated at 0.5 A, with integrated channel diagnostics (short- circuit, overload, wire-break). Certified to SIL 3 (IEC 61508) and PL e (EN ISO 13849-1), it interfaces via PROFIsafe over PROFIBUS or PROFINET (with the appropriate interface module) to deliver safe actuator control in emergency- stop, interlock, or safety-circuit applications.
