This module supports distributed I/O configurations through the PROFIBUS network.

Technical Specifications

The 6ES7142-6BF00-0AB0 measures 15.0 cm in height, 7.5 cm in width, and 7.0 cm in depth. It weighs approximately 0.35 kg, including all connectors and mounting hardware. This module draws 200 mA from the 24 VDC power supply under full load conditions. It features sixteen digital output channels with transistor switching technology. Each channel provides a maximum output current of 0.5 A at 24 VDC. The total output current limit across all channels reaches 8 A. The module offers a response time of 0.5 ms for high-speed switching applications. It provides optical isolation of 1500 VAC between the backplane and field circuits. Each output includes built-in short-circuit protection and thermal shutdown features. The front panel features sixteen green LED indicators for per-channel status monitoring. The module connects through a 40-pin connector for integration with the ET 200 system.

Output Characteristics and Protection

This module employs MOSFET switching for efficient and reliable load control. It drives solenoid valves, contactors, and indicator lamps with ease. The 6ES7142-6BF00-0AB0 includes integrated clamping diodes for inductive load protection. Users can configure fail-safe states for each channel through the system software. The module also provides diagnostic feedback for each output channel.
