• The compact, easy-to-use, and low-cost solution for simple control tasks
• Compact, easy to operate, universally applicable without accessories
• “All in one”: Integrated display and operator panel
• 36 different functions can be connected at the press of a button or using PC software; up to 130 times
• LOGO! 8: 38/43 Different functions can be linked at the press of a button or using PC software; up to 200/400 times
• Functions are easy to change at the press of a button. No more time-consuming rewiring

The LOGO! logic module is a convenient, user-friendly solution for simple open-loop and closed-loop control tasks.

LOGO! can be implemented universally, e.g.:

• Building services/electrical installation sector (lights, blinds, awnings, gates, access control points, barriers, ventilation systems…).
• Control cabinet manufacture.
• Mechanical engineering (pumps, small presses, compressors, lifting platforms, conveyor belts …).
• Special controls for conservatories, and greenhouses.
• Signal preprocessing for other controllers.

LOGO! logic modules are modular and can be flexibly expanded to suit the application.

LOGO! Modular is available in different versions for different connection voltages (12 V DC, 24 V DC, 24 V AC, 115/230 V DC, 115/230 V AC):

• Standard versions.
• Pure versions, cost-optimized without key control panel and display.

The LOGO! version have the following distinguishing features:

• R: Relay output.
• C: Clock/time switch.
• E: Ethernet interface.
• o: without display.

LOGO! is simple:

• Key control panel and display in one device. Further tools are not required.
• Power failure-proof backup of switching program and setpoints (e.g. timers) due to integrated EEPROM.

LOGO! saves space:

• e.g. LOGO! 230RC: 72 x 90 x 55 mm (W x H x D).
• Adapted installation in the distributor box (same dimensions as ground-fault circuit interrupter).

LOGO! offers maximum flexibility and can be implemented universally:

• Expandability:
  Expansion modules can be connected depending on the application.

LOGO! is communication-capable:

• Optional communication modules enable the connection to AS-Interface and KNX Konnex networks.
• LOGO! 7 and 8 can communicate with other LOGO! units or also with SIMATIC Controllers or SIMATIC Panels

LOGO! is simple:

• 36 different functions:
  stored basic functions (e.g. AND, OR) and special functions (e.g. counter, latching relay, PI controller) for electrical engineering.
• Program generation by simple combining of stored functions at the press of a key or using PC software.
• User-friendly and simple duplication of the control program by means of an optional program module.

LOGO! 8:

• 38 / 43 different functions: Integrated basic functions (e.g. AND, OR) and special functions (e.g. counter, latching relay, PI controller)
• User-friendly and simple duplication of the switching program by means of an optional program module or using a standard CF/micro CF card

LOGO! offers maximum flexibility and can be implemented universally:

• Flexible options for making changes by recombining functions at the press of a key. No more time-consuming rewiring.
• Optional operation on the PC:
  Creating, simulating, online testing and archiving the control program on the PC, incl. documentation options
