The 6ES7141-6BG00-0BB0 is an 8-channel digital input module from the SIMATIC ET 200eco PN M12-L generation. It provides 8 Type 3 inputs at 24V DC through individual M12 connectors and supports PROFINET, EtherNet/IP, and Modbus TCP on the same hardware. The M12-L generation adds configurable input filtering across eight delay levels, isochronous mode, and module shared input (MSI) over the previous generation.

How does the 8DI variant compare to the 16DI M12-L module?

Both share the same 60mm-wide zinc housing, MultiFieldbus capability, and configurable input delay. Choose the 8DI when eight inputs suffice and you prefer one-M12-per-channel wiring clarity. Choose the 16DI when channel density matters and you accept duplicate pin assignment.

What does configurable input delay enable for machine builders?

Input delay is parameterizable from 0.05ms to 20ms in eight steps. Short delays serve high-speed sensors in registration and positioning applications. Long delays debounce mechanical contacts and filter vibration noise without external signal conditioning. Each M12 channel can be configured independently, allowing mixed sensor types on the same module.

Frequently Asked Questions

What is the difference between 6ES7141-6BG00-0BB0 and 6ES7141-6BG00-0AB0?

The 0BB0 is the M12-L generation successor to the 0AB0. It adds MultiFieldbus support (EtherNet/IP and Modbus TCP in addition to PROFINET), configurable input delay, isochronous mode, and MSI. The 0AB0 is in phase-out status.

Does each M12 connector carry one or two input channels?

Each M12 connector carries one input channel with dedicated pins for sensor signal, 24V encoder supply, and ground, unlike the 16DI variant which uses duplicate assignment (two channels per M12). This one-to-one mapping simplifies field wiring and troubleshooting.
