The 6ES7141-5BF00-0BA0 is an 8-channel digital input module from the SIMATIC ET 200AL family, featuring M8 connectors in a 30mm-wide IP65/67 housing. It communicates via the ET 200AL backplane bus and supports safety-related tripping of standard actuators up to Performance Level d (PL d) per ISO 13849-1 and SIL 2 per IEC 62061.

How does the M8 variant compare to the M12 variant within ET 200AL?

M8 connectors save panel space and suit high-density sensor arrays where every millimeter counts. M12 connectors offer more robust locking and higher per-channel encoder supply current. Choose the connector size that matches your sensor cabling standard and space budget.

What does safety-related tripping provide for standard actuators?

This module participates in the safety function by disconnecting power to connected actuators when the safety circuit triggers. With PL d / SIL 2 certification, it supports emergency stop and safety gate functions without requiring safety-rated sensors at each input point. The module must be used within an ET 200AL station with a suitable safety-rated PROFINET controller. The IO-Link variant (6ES7141-5BF00-0BL0) does not offer this capability.

Frequently Asked Questions

What is the difference between 6ES7141-5BF00-0BA0 and 6ES7141-5BF00-0BL0?

The 0BA0 communicates via the ET 200AL backplane with a PROFINET interface module and supports safety-rated tripping up to PL d. The 0BL0 is an IO-Link device that connects directly to any IO-Link master without a backplane, but does not support safety functions. The 0BA0 requires a separate 24V DC supply; the 0BL0 draws power from the IO-Link master.

Can I use this module in a mixed station with other ET 200AL modules?

Yes. The 6ES7141-5BF00-0BA0 mounts on the standard ET 200AL backplane bus alongside digital output, analog, and technology modules. All modules in the station share the same interface module for PROFINET communication.
