LOGO! expansions

A wide range of expansion modules is available for the LOGO! to individually
expand your configuration. In this application example only digital expansion
modules are used on a LOGO! 8.
The maximum expansion of a LOGO! 8 depends on the basic device; a network
configuration enables more comprehensive configurations.
This is the quantities structure for the maximum possible expansion,

If your requirement includes further in- and outputs, you can join together several LOGO! 8 or
LOGO! 7 in a network. Via a master/slave configuration, you can combine up to (88 DI, 80 DQ, 40
AI and 24 AQ) in one circuit program.

LOGO! TDE

The LOGO! TDE external text display for LOGO! 8 provides you with an
inexpensive and central user interface for your applications. You have the
possibility to adjust parameters and use the LOGO! TDE for troubleshooting.
The configuration of LOGO! TDE is done using the same function block as for the
internal display.
The use of the TDE allows the display of all messages via the integrated web
server and thus also the control of applications via a smartphone.
