Siemens 6ES7143-5BF00-0BA0 SIMATIC ET 200AL DIQ 4+DQ 4x24VDC/0.5A M8 IP67 Remote I/O Module

The Siemens 6ES7143-5BF00-0BA0 is a SIMATIC ET 200AL I/O module with 4 fixed digital outputs and 4 channels parameterizable as input or output, rated 24 V DC / 0.5 A. It uses compact M8 field connectors across 8 ports rather than M12, still rated IP65/67, and supports PL d / Cat. 3 / SIL 2 safety-related tripping from FS01.

Technical Specifications

Selection Notes

Same 4 DQ-fixed plus 4 DIQ-parameterizable channel layout as the M12 version (6ES7143-5AF00-0BA0), but wired through 8x M8 3-pole connectors instead of 4x M12 5-pole. Pick this variant when the field cabling is already M8, which is smaller and cheaper per connection but carries only single-signal, non-multiplexed wiring. PL d / Cat. 3 / SIL 2 tripping support from FS01 carries over unchanged from the M12 variant.

Applications

Suits machine-mounted digital I/O where the plant standard is M8 field connectors, such as sensor-dense zones on packaging or handling equipment where connector size and cost per point matter more than multi-signal M12 cabling.
