The 8 inputs accept 24 V DC signals with a '1' threshold of 13 to 30 V and a '0' threshold of -3 to +5 V — standard for Siemens S7-family 24 V logic, so it drops into existing sensor wiring without level shifting. Each of the 4 outputs is rated 0.9 A up to 40 °C; above that, derate to 8 A total across all outputs at 55 °C — the per-channel limit is the package's thermal budget, not a per-pin spec, so parallel high-current loads need care. The module accepts 2-wire sensors with a quiescent current up to 1.5 mA, and unshielded cable runs up to 30 m — enough for distributed sensors on a machine cell without remote I/O drops. Output switching times: 1.2 ms min to 4.8 ms max for 0→1, and 1.2 ms min to 4.8 µs max for 1→0 — fast enough for valve banks and indicator lamps, not for high-speed counting. Power loss is 1.5 W typical, drawn from the backplane bus at 5 V DC (16 mA max) — negligible for the ET 200X power budget, but confirm the bus supply can handle the cumulative load of all modules. Isolation tested at 500 V DC between circuits, with 75 V DC / 60 V AC between different circuits — no galvanic separation between inputs and the backplane, so the module shares ground with the CPU. ## Deployment context The IP65 rating and M12 connectors mean this module is designed for on-machine mounting — washdown zones, conveyor lines, packaging cells — where a cabinet-mounted I/O block would be impractical.","metaTitle":"Siemens 6ES7141-1BF31-0XA0 EM 141 ET 200X, 8 DI 24 V DC, M12","metaDescription":"Siemens 6ES7141-1BF31-0XA0 spare part: ET 200X EM 141 expansion module, 8 digital inputs 24 V DC, 4 outputs, M12 double assigned, IP65.
