Siemens 6ES7138-4CF03-0AB0 Programmable Logic Controller Module

Siemens 6ES7138-4CF03-0AB0 is a PM-E F PROFIsafe power module for the ET 200S distributed I/O system, providing a 24 V DC supply and two fail-safe digital outputs rated up to Category 4 (EN 954-1), SIL3 (IEC 61508), and PLE (ISO 13849). It is designed to enable PROFIsafe safety functionality within ET 200S configurations and can be used in PROFINET networks when paired with an IM 151-3 HF interface module. The module facilitates safe switching of the voltage buses P1 and P2 via ungrounded reference potential relays, making it suitable for safety-related control tasks in automation environments. As a spare-part PM-E F PROFIsafe for ET 200S, it integrates with Siemens’ safety ecosystem to extend reliability across distributed I/O installations.
