At a Glance

Brand	Siemens
Model	6ES7193-4CA50-0AA0
Product Type	Universal electronic module base
Core Function	Extended sensor and actuator termination
Application	ET 200S electronic modules

Full numbered terminal set

Numbered connections 1–8 are retained for the electronic module.

Four auxiliary connections

A3, A4, A7 and A8 provide local access to the continuous AUX1 potential.

Tall universal format

The 157 mm terminal arrangement accommodates the additional connection points.

Product Overview

6ES7193-4CA50-0AA0 provides the universal TM-E15C26-A1 terminal pattern with spring-loaded field connections.

The electronic module assigns the eight numbered terminals, while four extra auxiliary positions support more extensive field wiring without consuming those numbered positions.

Ordering focus: Match the universal terminal pattern to the electronic module and allow for its 157 mm housing height and continuous AUX1 path.

Key Functions

Preserve all signal positions

Terminals 1 through 8 are available for the inserted electronic module and its circuit assignment.

Land auxiliary conductors separately

Four auxiliary terminals connect directly to the continuous AUX1 bus.

Secure conductors with spring contacts

A 3 mm screwdriver operates the spring mechanism after each conductor has been stripped to the specified length.

Frequently Asked Questions

Does 6ES7193-4CA50-0AA0 sacrifice terminals 4 and 8 to provide AUX1?

No, the universal layout retains numbered terminals 1–8 and provides four separate auxiliary terminals.

How do I release a spring contact on 6ES7193-4CA50-0AA0?

Insert a screwdriver with a 3 mm blade into the upper round opening to release the conductor held in the lower square opening.

Can 6ES7193-4CA50-0AA0 separate the auxiliary potential between adjacent groups?

No, its AUX1 bus is electrically continuous to the potential group on the left.

Will 6ES7193-4CA50-0AA0 fit in the same vertical envelope as a 120 mm terminal base?

No, this universal base is 157 mm high and needs the corresponding additional clearance.

Which prepared conductor size can I connect to 6ES7193-4CA50-0AA0?

Flexible conductors with ferrules may have cross-sections from 0.14 to 1.5 mm².

Does 6ES7193-4CA50-0AA0 accept the 4DO ST module 6ES7132-4BD02-0AA0?

Yes, the universal TM-E15C26-A1 spring-terminal base is included among the compatible terminal-module options for that output module.

How much insulation should be removed before wiring 6ES7193-4CA50-0AA0?

Strip 11 mm of insulation before inserting each conductor into the terminal.

Compatibility & Ordering Notes

Before ordering 6ES7193-4CA50-0AA0: Choose the universal 2 × 6 spring-terminal pattern when eight numbered connections plus four AUX1 positions are needed, and preserve the intended common auxiliary potential.

Compatibility Checklist for 6ES7193-4CA50-0AA0

• Match numbered terminals to the inserted electronic module.
• Treat all four AUX1 positions as the same auxiliary bus.
• Allow for the 157 mm housing height.
