    Answers for industry.

    Micro Automation

  • Transport facilities

    Conveyor systems Hoisting platforms Elevators Silo works Automatic feeders

    Residential and commercial building services

    Lighting control Door/gate control Shutters, blinds and awning control Watering and sprinkler system control

    Unique applications

    Solar-electric systems Marine Harsh environments Display panels and traffic control signs

    Switching and controlling the profitable way

    Every decision maker faces mounting pressure to increase production while reducing

    waste, energy costs, and maintenance downtime - all with a shrinking workforce. Those

    with innovative ideas are looking to their industrial partners for flexible controllers that

    perform multiple operations requiring minimal troubleshooting and maintenance. No other

    programmable relay satisfies these requirements better than LOGO! the original and best

    selling programmable relay worldwide.

    Operational monitoring systems

    Access control Vehicle control monitoring Alarm systems Limit-value monitoring Traffic light control systems Baggage control

    Maximum flexibility through consistent modularity

    The modular design of LOGO! enables flexible control systems for small or large systems. A wide range of modules allows individual expansion of LOGO! to 24 digital inputs, 16 digital outputs, 8 analog inputs and 2 analog outputs! Communication modules are also availa-ble for AS-Interface and KNX (Instabus network for building automation). Examples using the analog output module to solve simple closed-loop control tasks are included. Heating and cooling systems can be designed with the RTD PT100 module using special func-tions for PI control, ramp response and analog multiplexer.

    Proven millions of times in numerous applications

    Together with the LOGO! Comfort, a software, configuring of our programma-ble relay is childs play: program genera-tion, project simulation and documenta-tion are accomplished simply using drag and drop functionality, allowing maximum ease of operation. LOGO! includes maximum functionality: backlit display, efficient line usage, and the ca-pability for directly modifying message texts for optimum customer satisfaction. LOGO! has proven successes in a multitude of applications.

    Advanced intelligent technology

    The LOGO! system from Siemens is the ideal controller for simple automation tasks in industry and building services. The intelligent programmable relay features maximum user friendliness and satisfies nearly every functional requirement with high speed precision, efficient instructions and memory design. Applications can easily be accomplished with LOGO! and its large selection of expansion modules.


  • Even more ingenious also with external text display

    Welcome the LOGO! TD text display HMI, the newest addition to the LOGO! line of

    programmable relays. LOGO! TD provides an affordable HMI for equipment builders

    and their customers, even on the simplest relay control systems. Make quick

    adjustments and troubleshoot failures easily using LOGO! TD with built-in operator

    functions and diagnostics.


  • Performance optimized further

    The new LOGO! 7th generation (version 0BA6) offers expanded program memory by more than 50 % now with 200 function blocks. Other hardware upgrades include basic and pure models being expanded to 4 channels of 0-10V built-in analog inputs, and 4 channels of configura-ble 5Khz high speed counting inputs. All prior generation expansion modules and user programs are upward compat-ible to 7th generation controllers.

    Expanded Functionality

    LOGO! 7th generation built-in display is now brighter and supports up to 50 configurable four-line message blocks with an optional text ticker feature showcasing 24 charac-ters per line. Additional software enhancements include special analog math functions for basic scaling or average calculations, and built-in PWM (pulse width modulation) function for heater control applications.

    LOGO! gets an HMI

    The LOGO! TD is a backlit four-line LCD supporting text or numeric displays up to 24 characters per line, with six buttons for screen navigation and data entry, along with four user function buttons. With a built-in horizontal and vertical bar graph display feature, viewing options are not limited to text only. The bar graph display modes can be configured to represent any numeric value in the LOGO! controller, including an attached tank level sensor, flow rate, rpm, counts, time, cycles and more. All LOGO! control functions and LOGO! TD screens are developed in a single Soft Comfort software user program, eliminating the need to maintain separate PLC and HMI programs.

  • The LOGO! hardware

    LOGO! offers the widest range of capabilities and successful implementation of extensive applications

    with the option of selecting 38 integrated functions and linking them with up to 200 blocks. With its wide

    variety of available I/O, LOGO! offers more options for direct-to-device connection than any other

    controller. LOGO! systems can now now be easily selected for almost any small industrial application and

    also for non-manufacturing commercial applications.
