Siemens 6ES7138-4CF41-0AB0 Profinet Interface Module

Siemens 6ES7138-4CF41-0AB0 is a SIMATIC DP power module (PM-E F PROFISAFE) designed for ET 200S distributed I/O systems, enabling safe, PROFIsafe-rated operation within PROFINET/DP networks. It provides 24 V DC power to the safety domain and supports fail-safe switching of the voltage bus P2 up to Category 3 (EN 954-1) with SIL 2 (IEC 61508) certification, making it suitable for safety-critical installations. The module is intended to be used in PROFINET configurations when paired with compatible ET 200S interface offerings (for example IM151-3 HF), enabling seamless PROFINET IO integration within the Siemens SIMATIC portfolio. This order-specific variant identifies the PM-E F PROFISAFE configuration for ET 200S, delivering a dedicated, isolated power path to safety I/O while remaining compatible with standard DP/PROFINET networks.
