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! Expansion Modules

LOGO! Expansion Modules

A wide range of expansion modules allows the user to set up a flexible LOGO! Configuration with a maximum of 24 digital inputs, 20 digital outputs, 8 analog inputs and 8 analog outputs possible.

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.

Operator Devices

Operator Devices

LOGO! TDE and SIMATIC Basic Panels offer simple operator control and monitoring possibilities.

LOGO! Software

LOGO! Software

LOGO! Software supports small automation projects with simple and intuitive configuration and operation, from the engineering software LOGO! Soft Comfort, to the LOGO! Access Tool, and also the LOGO! Web Editor for the web server integrated into LOGO!

LOGO! in practical use

LOGO! inspires and motivates

LOGO! is much more than just a compact controller: It motivates people to explore new paths and try out new things. The Cloud connection opens up even more possibilities. Try it and be inspired!
