Siemens 6ES7142-0BF11-0XB0 Output Module

This digital output module drives 24 VDC actuators and indicators for Siemens ET 200X distributed I/O systems. It provides reliable switching for solenoids, contactors, and signal lamps in industrial applications. The module’s compact IP65/IP67 housing suits harsh environments requiring protection against dust and moisture.

Output Configuration and Electrical Ratings

The Siemens 6ES7142-0BF11-0XB0 features four digital outputs, each with a nominal voltage of 24 VDC and maximum current of 1.2 A. Each output includes short-circuit protection and thermal overload protection for reliable operation. The module draws a maximum current of 70 mA from the 24 VDC power supply. It also consumes 40 mA from the internal 5 VDC backplane bus. The module can drive inductive loads up to 2.0 H without additional suppression components.
