It provides 8 digital inputs at 24 V DC, with the input thresholds defined as -3 to +5 V for signal 0 and 13 to 30 V for signal 1, making it compatible with standard 24 V DC sensors and 2-wire sensors (quiescent current up to 1.5 mA). The module integrates a PROFIBUS DP slave interface supporting transmission rates from 9.6 kbit/s up to 12 Mbit/s, and supports direct data exchange (slave-to-slave communication) as a sender. Rated for IP66/67 protection, the module is sealed for washdown environments — food, beverage, or any area where hose-down cleaning is routine. The M12 5-pin double-assignment connectors keep field wiring tidy and reduce the number of panel penetrations. The 8 digital inputs are electronically short-circuit protected, but note there is no reverse polarity protection on the supply — verify polarity at the 24 V DC feed before powering up. The module draws up to 180 mA from the 1L+ supply, which matters when calculating the total current budget for the ET 200X station. Typical power loss is 3.5 W, low enough that no special cooling is needed inside a standard IP66 enclosure. The module supports up to 7 expansion modules in the station, of which up to 6 can be pneumatic interfaces or motor starters/frequency converters — useful when mixing I/O with actuators on the same backplane. Input response times range from 1.2 ms (min) to 4.8 ms (max) for a 0-to-1 transition, adequate for most discrete sensing but not for high-speed counting or encoder capture. Unshielded sensor cables can run up to 30 m, which covers most machine-mounted sensor runs without extra shielding. The module measures 134 mm wide (module width 107 mm), 110 mm high, and 55 mm deep — it mounts directly onto the ET 200X backplane without additional DIN-rail hardware. The integrated PROFIBUS DP interface uses a standard 5-pin M12 connector, so no separate bus coupler is needed. Plan for the 55 mm depth when sizing the enclosure; it fits most standard junction boxes.","metaTitle":"Siemens 6ES7141-1BF11-0XB0 SIMATIC DP BM141, 8 DI 24V DC, PR","metaDescription":"Siemens 6ES7141-1BF11-0XB0 SIMATIC DP basic module BM141 ET 200X, 8 digital inputs 24V DC, PROFIBUS DP slave up to 12 Mbit/s, IP66/67.
