Siemens 6ES7147-6AB00-0BB0 SIMATIC ET 200eco PN TM PosInput 2 Remote I/O Module

The Siemens 6ES7147-6AB00-0BB0 is a SIMATIC ET 200eco PN TM PosInput 2 counting and position-detection module with 2 channels, each accepting SSI absolute encoders, RS-422 incremental encoders, or 24 V incremental encoders, plus 2 digital inputs and 2 digital outputs per channel. It supports isochronous mode, fast and prioritized startup, and PROFINET IRT down to 500 microseconds over 2 M12 ports with an integrated switch.

Technical Specifications

Selection Notes

Each of the 2 channels accepts SSI absolute, RS-422 incremental, or 24 V incremental encoder signals without changing hardware, so the module fits axes that may later swap encoder type. Counting frequency reaches 4 MHz on RS-422 incremental encoders with quadruple evaluation, versus 800 kHz on 24 V incremental encoders, which sets the practical resolution and speed ceiling per encoder class. PROFINET IRT support down to 500 microseconds with isochronous mode and fast/prioritized startup fits motion axes on a synchronized PROFINET segment.

Applications

Fits positioning and counting axes using SSI, RS-422, or 24 V incremental encoders on a PROFINET IRT segment where isochronous, synchronized position feedback is required.
