Description:
The Siemens 6ES7 138-4FA04-0AB0 is an ET200S safety digital input module (4/8 F-DI, DC 24V) designed for PROFIsafe networks. It provides eight safety-related digital inputs at SIL-2 or four safety digital inputs at SIL-3, with built-in diagnostics to monitor channel health and deliver fault information for safe operation. As a fail-safe input expansion for distributed safety control, it integrates with front-end safety peripherals such as the 3SK1 safety relay and plugs into SIMATIC Safety Integrated architectures like PCS 7, enabling reliable sensing of safety-related signals across an ET200S I/O network.
