The Siemens 6ES7141-4BF00-0AB0 is an ET 200 PRO electronic module packing eight 24 V DC digital inputs with channel-level diagnostics, wire-break monitoring, and short-circuit protection — all on a 35 mm deep body that slides into the bus module.
Signal diagnostics worth tracing
Short-circuit protection is electronic per channel. Diagnostic alarm and group error LED (red SF) are available; diagnostics are parameterizable.
This module is listed as current and is a standard catalog line for ET 200 PRO; wiring requires a separate bus module (6ES7194-4..00-0AA0) and connection module, ordered separately. Dimensions (width 45 mm, height 130 mm, depth 35 mm) fit the existing PRO footprint exactly — no panel rework for a direct swap-in.
