Product Description: Siemens 6ES7138-4FB03-0AB0

The Siemens 6ES7138-4FB03-0AB0 is a failsafe digital input module from the SIMATIC ET 200S series, designed for safety-related automation systems. It provides 8 digital inputs for 24 V DC signals and supports safety functions in accordance with SIL 3 (IEC 61508) and PL e (EN ISO 13849-1). This High Feature (HF) module is used for applications requiring secure monitoring of safety sensors such as emergency stop buttons, light curtains, or door switches. The module operates in conjunction with a safety- capable controller (e.g., S7 F-CPU) via PROFIsafe over PROFIBUS and integrates seamlessly into TIA Portal or STEP 7 for configuration and diagnostics.
