Product details

Lead

The Siemens 6ES7141-1BF10-0XB0 is a SIMATIC DP Basic Module BM141 for the ET 200X distributed I/O family, carrying eight 24V DC digital inputs on M12 connectors with PROFIBUS DP slave interface. PROFIBUS DP transmission rate up to 12 Mbit/s, rates include 9,6 / 19,2 / 93,75 / 187,5 / 500 kbit/s and 1,5 / 3 / 6 / 12 Mbit/s. Unshielded cable max. 30 m. Module dimensions are 134 mm wide (107 mm module body), 110 mm high, and 55 mm deep. Power draw is 3.5 W typical; max current from the supply voltage is 180 mA. Rated IP66/67, the BM141 is designed for direct field mounting on the ET 200X backplane, supporting up to seven expansion modules (six of which can be pneumatic interfaces or motor starters/frequency converters).

Frequently asked questions

What is the depth of the module?

55 mm.

Can the 6ES7141-1BF10-0XB0 replace the 6AG1123-2DB03-2AX0 in a panel?

No. The 6AG1123-2DB03-2AX0 is an HMI with different dimensions, interfaces (PROFINET not PROFIBUS), and environmental rating – it is not a functional alternative for this BM141 I/O module.
