Siemens 6ES7143-5AH00-0BA0 SIMATIC ET 200AL DIQ 16x24VDC/0.5A IP67 Remote I/O Module

The Siemens 6ES7143-5AH00-0BA0 is a SIMATIC ET 200AL I/O module with 16 channels parameterizable as digital input, output, or fast counter, rated 24 V DC / 0.5 A. Eight M12 ports give it IP65/67 protection for machine-mounted installation, and up to 4 channels can run as 2 kHz counters with 32-bit width.

Technical Specifications

Selection Notes

Every one of the 16 channels can be set as input, output, or counter in the engineering tool, so this module replaces a fixed-ratio I/O card when a station's DI/DO mix changes between projects or machine variants. The 2 kHz, 32-bit counting function on up to 4 channels covers basic encoder or flow-pulse counting without adding a dedicated counter module. Choose the fixed DIQ 4+DQ 4 variant instead when the mix is known and the smaller 30 mm housing width matters more than channel flexibility.

Applications

Suits IP67 machine-mounted stations where the digital I/O ratio isn't fixed at design time, or where a handful of channels need pulse counting alongside standard DI/DO, such as packaging or conveyor cells with integrated encoders.
