Siemens 6ES7193-0CA10-0XA0 SIMATIC DP ET 200B Terminal Block

TB1/DC connection base for digital electronic submodules with three-wire screw terminals

Product Overview

Siemens 6ES7193-0CA10-0XA0 is a SIMATIC DP TB1/DC terminal block for the ET 200B distributed I/O system. The Siemens data sheet specifies use with digital electronic submodules and a three-wire screw-terminal arrangement. Its 160 mm width and 24 V DC internal logic supply make it a defined mechanical and electrical connection base for legacy ET 200B assemblies. Procurement should be based on the complete order number because related TB1, TB2, TB3 and four-wire variants are not interchangeable by description alone.

Verified Technical Data

System Fit and Applications

This terminal block provides the field-wiring and base connection point for compatible digital electronic submodules in a Siemens ET 200B distributed I/O station. Typical use includes maintenance of existing PROFIBUS DP remote I/O nodes, replacement of damaged terminal bases and controlled retrofit support where the original wiring architecture must remain unchanged.

Application boundaries

The part number identifies a TB1/DC three-wire screw-terminal version. It should not be selected for an analog submodule, spring-terminal requirement, four-wire field circuit or a different ET 200 family without a documented engineering review.

Compatibility and Procurement Checks

• Match the complete order number 6ES7193-0CA10-0XA0, including the 0XA0 suffix.
• Confirm the ET 200B electronic submodule type and TB1/DC mounting requirement.
• Verify the three-wire screw-terminal field wiring and 160 mm mechanical width.
• Check the 24 V DC supply range, terminal assignment and PROFIBUS DP station documentation.
• Compare installed labeling, connector condition and wiring drawings before replacement.
