Product Information

Full details

The Siemens LOGO! DM8 230R expansion module is designed for small automation tasks in industrial and building applications, offering 4 digital inputs and 4 relay outputs. Its key benefit is extending the control capabilities of LOGO! 8 base modules with reliable relay outputs suitable for various loads. A caveat to consider is that it requires a separate power supply unit and is not intended for standalone operation.

FAQs

What is the maximum load current for the relay outputs?

Each relay output has a contact current capacity of 5A.

Can this module be used without a LOGO! 8 base module?

No, the LOGO! DM8 230R is an expansion module and requires a compatible LOGO! 8 base module to function.

What type of voltage can be connected to the inputs?

The digital inputs accept AC/DC voltage in the range of 0 to 265V.

How is the module mounted?

The module is designed for mounting on a standard 35mm DIN rail.

What is the operating temperature range?

The module operates within an ambient temperature range of -20 to 55 °C.

Can I control this module remotely via a smartphone?

Remote control via smartphone is possible by integrating the LOGO! CMR module with your LOGO! 8 system.

What software is used to program this module?

Programming is done using Siemens LOGO! Soft Comfort or the LOGO! Web Editor, in conjunction with the base module.

Troubleshooting

Module not recognized by base module

Verify the communication cable connection between the base module and the expansion module. Ensure the base module firmware is updated and compatible with the expansion module.

Relay outputs not switching

Check the wiring to the output terminals and ensure the load connected is within the 5A rating. Verify the program logic controlling the output and confirm the correct supply voltage is present.

Digital inputs not registering signals

Confirm the input wiring is correct and that the voltage applied to the input is within the 0-265V range (AC/DC). Check the input configuration in the LOGO! Soft Comfort software.

Module powers on but does not function

Ensure the correct supply voltage (AC or DC) is connected to the appropriate terminals. Restart the system by cycling power to both the base module and the expansion module.

Pros and Cons

Pros

  • Versatile power supply accommodates AC and DC sources.
  • Reliable relay outputs are suitable for a wide range of loads.
  • Easy integration with existing Siemens LOGO! 8 systems.
  • Compact design with DIN rail mounting for efficient cabinet use.
  • Offers basic communication features for alerts via text messages.

Cons

  • Requires a separate LOGO! base module for operation.
  • Limited number of inputs and outputs for complex tasks.
  • Text message communication requires additional configuration (e.g., CMR module).
  • Not suitable for high-frequency switching applications due to relay limitations.

Setup, Compatibility & Care

Setup:

  1. Ensure the LOGO! 8 base module is already installed and configured.
  2. Mount the LOGO! DM8 230R expansion module onto a standard 35mm DIN rail adjacent to the base module.
  3. Connect the power supply (85-265V AC or 100-253V DC) to the designated power terminals on the module.
  4. Wire the digital inputs and relay outputs using the screw terminals according to your schematic.
  5. Connect the expansion module to the LOGO! 8 base module using the appropriate communication cable (sold separately).
  6. Download your configured program from LOGO! Soft Comfort or LOGO! Web Editor to the base module.

Compatibility:

  • This module is designed exclusively for use with Siemens LOGO! 8 series base modules.
  • Ensure your LOGO! 8 base module firmware is up-to-date for optimal compatibility.

Care:

  • Keep the module clean and free from dust and debris. Use a dry or slightly damp cloth for cleaning; avoid solvents.
  • Ensure proper ventilation around the module within the control cabinet.
  • Periodically check screw terminal connections for tightness.
