Siemens 6ES7143-5AF00-0BA0 SIMATIC ET 200AL DIQ 4+DQ 4x24VDC/0.5A IP67 Remote I/O Module

The Siemens 6ES7143-5AF00-0BA0 is a SIMATIC ET 200AL I/O module with 4 fixed digital outputs and 4 channels parameterizable as input or output, all rated 24 V DC / 0.5 A. It connects through four M12 ports at IP65/67, so it mounts directly in the machine without a control cabinet. PROFINET GSDML V2.3.1 and PROFIBUS GSD Revision 5 cover engineering.

Technical Specifications

Selection Notes

The 4 DQ-fixed plus 4 DIQ-parameterizable layout lets one module cover either a 4-in/4-out split or an 8-output block, set in the engineering tool rather than by ordering a different part. Pick it over the ET 200AL 16-channel variants when the station only needs a handful of M12 field connections and the compact 30 mm housing width matters for panel space. PL d / Cat. 3 / SIL 2 tripping support from FS01 lets it forward safety-related shutdown signals alongside standard I/O.

Applications

Suits machine-mounted stations at IP67 where cabling runs directly to sensors and actuators without a cabinet, such as conveyor zones or small assembly cells. The PROFINET/PROFIBUS GSD support lets it integrate into either fieldbus without a separate module variant.
