Siemens 6ES7138-4FA04-0AB0 Programmable Logic Controller Module

Siemens 6ES7138-4FA04-0AB0 is a SIMATIC ET 200S DP electronics module for PROFISAFE digital inputs, housed in a 30 mm wide enclosure and designed for 24 V DC operation. As an electronics module for ET200S, it provides PROFISAFE digital input capability with 4/8 F-DI PROFISAFE inputs, enabling safety-related signals to be monitored and transmitted over a PROFIBUS DP or PROFINET network. The module supports safety-rated performance up to Category 4 according to EN 954-1 and SIL3 per IEC 62061, and it can be used in PROFINET networks via IM151-3 HF. It accepts a 24 V DC supply with a permissible range of 20.4 to 28.8 V and offers robust, safe input processing for distributed automation tasks. The compact 30 mm width supports space‑conscious cabinet layouts while ensuring seamless integration with Siemens controllers and the ET200S family for scalable, safety‑oriented control architectures.
