Siemens 6ES7138-4FB03-0AB0 Electronics Module

Siemens 6ES7138-4FB03-0AB0 is a SIMATIC DP electronics module for the ET 200S distributed I/O system, delivering four PROFIsafe digital outputs (F-DO) and powered from 24 V DC with a 2 A supply rating. It fits in a 30 mm-wide ET 200S slot and draws about 28 mA (typical) with power losses around 3.5 W during normal operation. The module supports safety-rated performance up to Category 4 EN 954-1, SIL3 IEC 61508, and PL E ISO 13849, making it suitable for safety-related control circuits. When used with a PROFINET configuration, it can operate via the IM 151-3 HF interface, and Siemens lists it as a spare part for SIMATIC DP ET 200S systems.
