Short Description

The Terminal Bases TB51x to TB54x are used as sockets for Processor Modules and Communication Modules. Up to 10 I/O Terminal Units for I/O expansion modules can be added to these Terminal Bases.

The Terminal Bases have slots for one Processor Module and for Communication Modules as well as terminals and interfaces for power supply, expansion and networking.

Number of slots:

Terminal Base	TB51x	TB52x	TB54x
Slots for Processor Modules	1	1	1
Slots for Communication Modules	1	2	4

Warning

:strong:Risk of malfunctions and damages to persons!

Unused slots for Communication Modules are not protected against accidentally touch. Dust and Dirt may cause contact problems and malfunctions.

Unused slots for Communication Modules must be covered with Dummy Communication Modules (TA524 TA524 - Dummy Communication Module).

I/O-Bus connectors must not be touched during operation.
