Siemens 6ES7-148-4FA00-0AB0 Electrical Module

Siemens ET 200PRO Fail-Safe Electronic Module, 8/16 F-DI DC24V PROFIsafe (order 6ES7 148-4FA00-0AB0), is a fail-safe digital input module designed for the ET 200PRO distributed I/O system. It provides 24V DC digital input channels with PROFIsafe signaling, enabling safe monitoring of critical inputs and reliable communication with a compatible safety controller over the PROFIsafe network. As part of the ET 200PRO fail-safe family, this module can be paired with safety accessories such as the CM 16×M12 connection module for 8/16 F-DI (order 6ES7 194-4DD00-0AA0) to facilitate field wiring and integration in safety-focused automation. The module is intended for industrial environments where safety-rated I/O is required and is documented in Siemens' ET 200PRO fail-safe system manuals and annexes. Exact channel count and wiring options depend on configuration; in the 8/16 F-DI variant, the model is optimized for compact, safety-certified input sensing within the ET 200PRO ecosystem.
