## Summary description

The Siemens LOGO! DM8 230R (6ED1055-1FB00-0BA2) is a digital expansion module designed for LOGO! logic modules. It features 230V AC input voltage and relay outputs with a 5A contact current capacity. This module is essential for increasing the number of inputs and outputs in industrial automation and control systems, ensuring reliable signal processing and switching in various electrical applications.

## Long description

The Siemens LOGO! DM8 230R is a high-performance digital expansion module specifically engineered to extend the capabilities of the LOGO! logic module series. This unit provides additional input and output points, allowing for more complex control configurations in industrial and building automation environments. Operating on a 230V AC supply, it ensures seamless integration into existing electrical systems, providing robust signal processing and reliable switching through its integrated relay outputs.
Advantages
This expansion module offers significant flexibility for automation projects by allowing users to scale their control systems according to specific requirements. Its design focuses on durability and ease of installation, making it a reliable choice for demanding industrial applications. The inclusion of relay outputs provides high current handling capabilities, which simplifies the control of external devices such as contactors, valves, or indicator lights without the need for additional intermediate relays.
Suitable for
Industrial automation and control systems
Building management and lighting control
HVAC system integration
Small-scale machinery automation
Process monitoring and signal switching
When it may not be suitable
This module is designed exclusively for 230V AC systems and is not compatible with low-voltage DC control circuits. It should not be used in applications requiring high-speed pulse counting or analog signal processing, as it is strictly a digital I/O expansion unit.
Key specifications
Input voltage: 230V AC
Output type: Relay
Maximum switching current: 5A
Compatibility: LOGO! logic modules
Mounting: DIN rail
How to use
To integrate the module, mount it onto a standard DIN rail adjacent to the main LOGO! base module. Connect the expansion bus cable to the interface port on the side of the base unit. Wire your digital inputs and relay outputs according to the terminal diagram provided on the housing. Ensure that the power supply matches the 230V AC requirement before energizing the system. Once connected, the LOGO! software will automatically detect the additional I/O points for configuration within your control program.
What to consider before purchase
Verify that your existing LOGO! base module supports expansion modules
Ensure the power supply voltage matches the 230V AC specification
Check that the 5A relay output capacity is sufficient for your connected loads
Confirm available space on the DIN rail for the additional module width
Usage recommendations
Always ensure that the power is disconnected during installation and wiring to prevent electrical hazards. Use appropriate wire gauges and ferrules for secure terminal connections, and verify that the total load on the relay outputs does not exceed the specified 5A limit to maintain long-term operational reliability.
