Siemens 6ES7138-6BA01-0BA0 TM PosInput 1 Module

Counter and position detection for RS-422 incremental encoders or SSI absolute encoders.

Purpose in the Station

The Siemens 6ES7138-6BA01-0BA0 is a SIMATIC ET 200SP TM PosInput 1 counter and position detection module. It is designed to process position and counting signals from RS-422 incremental encoders or SSI absolute encoders within compatible ET 200SP installations. The module combines one position/counter channel with two digital inputs and two digital outputs and is intended for BaseUnit type A0.

It suits machine retrofits, line upgrades, motion-feedback tasks and maintenance replacement where the exact Siemens article number must be matched. Before ordering, confirm the complete part number, BaseUnit type, encoder interface, wiring assignment, station configuration, required revision and destination.

Key Product Information

Signal-to-Decision Path

Applications and Engineering Fit

• Position feedback: acquire supported encoder signals for machine-axis or mechanism position tasks.
• Industrial counting: integrate counting functions into an ET 200SP distributed I/O station.
• Equipment modernization: replace a matched module while retaining the approved Siemens article number and system design.
• Maintenance spares: support planned outages where encoder interface, BaseUnit and revision are documented.

Compatibility and Installation Notice

The complete suffix 6ES7138-6BA01-0BA0 matters. Confirm the encoder technology, signal level, BaseUnit type A0, terminal assignment, ET 200SP station configuration and parameterization before installation. Hardware or firmware requirements must be checked against the installed system documentation.

Send a photo of the original module label and station layout when requesting a replacement. Please contact us to confirm the exact revision, firmware version, condition and availability before ordering.
