Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 6ES7138-4DF01-0AB0 is a Siemens SIMATIC ET 200S electronic interface module ("1 SI") that provides a single-channel serial communication link supporting RS-232C, RS-422, and RS-485 physical layers and ASCII or 3964(R) protocol processing. It occupies 15 mm of DIN-rail width and mounts onto an ET 200S distributed I/O assembly. It connects serial field devices into a PROFIBUS-DP (SIMATIC DP) control system. Typical applications include integration of older serial instruments, barcode readers, or legacy devices into ET 200S installations.
Best Suited For
- Integrating legacy serial devices (RS-232/422/485) into ET 200S systems
- Implementing ASCII or 3964(R) protocol communication in ET 200S
- Fieldbus expansion where compact interface modules are required
- Spare-part replacement for existing ET 200S serial interface modules
