25 years – LOGO! celebrates anniversary

The exciting way from logic module to controller with cloud connection

In the past 25 years, not only the world has changed a lot, but LOGO! has also experienced a lot since its birth in 1996. Launched as a logic module to close the gap between relays and controllers, LOGO! today even has a direct line to the cloud.

Join us on a on a short journey through time and get to know the people behind 25 years of LOGO!.

The people behind 25 years of LOGO!

LOGO! Basic Modules

LOGO! Basic Modules

LOGO! is the perfect choice as a fast, uncomplicated and space-saving solution for basic control tasks. LOGO! has long been a constant as an intelligent logic module for small automation projects.

LOGO!Power & Inrush current limiter

LOGO!Power & Inrush current limiter

The mini power supply devices designed like LOGO! modules offer great performance in the smallest space: The excellent efficiency over the complete load range and the low performance loss during idle times guarantee efficient operation.


The mini inrush current limiter in LOGO! design offers special protection in the smallest space:

As an upstream device in front of AC 230 V LOGO! basic or LOGO!power modules the LOGO! ICL230 reduces the inrush current.

For DC 24 V devices with high inrush currents the up streamed LOGO! relay module is protected against these excessive inrush current by the LOGO! ICL230.

LOGO! Communication

LOGO! Communication

The LOGO! family offers many communication options. In LOGO! 8, the connection to the communication modules is done via Ethernet. This means the entire address range of the inputs/outputs remains available for digital and analog signals.
