The Siemens 6ES7141-4BF00-0AA0 is a SIMATIC ET 200pro digital electronic module with eight 24 V DC inputs and module-level diagnostics. It uses P-reading input logic, accepts signal-1 levels from 13 to 30 V and signal-0 levels from −3 to +5 V, and draws approximately 7 mA for an active input. The module consumes up to 20 mA from both the 24 V supply and the 3.3 V backplane bus, provides electronically protected encoder supply outputs, and has a typical power loss of 2.5 W. The 6ES7141-4BF00-0AA0 supports robust distributed I/O acquisition in ET 200pro installations.

Collects proximity-switch, limit-switch, and position signals from distributed conveyor sections and transfer stations.

Connects eight 24 V DC sensors near filling, labeling, wrapping, and end-of-line equipment.

Acquires fixture, clamp, part-present, and station-status signals in cabinet-free automation zones.

Monitors valves, pressure switches, level switches, and equipment status on pumping, dosing, and filtration skids.

Supports sensor acquisition for automated storage, retrieval, sorting, and handling systems.

Restores distributed digital-input capacity during exact-model replacement, maintenance, and machine refurbishment.
