Product Description

The Siemens LOGO! Contact Module (6ED1057-4BA01-0AA0) is a dedicated relay expansion module designed exclusively for the Siemens LOGO! logic module family. It is often referred to as a LOGO! DM8 230R.

• Type: Digital Output (DO) Relay Expansion Module.

• Designation: LOGO! DM8 230R.

• Function: Its primary purpose is to expand the number of physical digital outputs available to the main LOGO! controller (e.g., LOGO! 8 or earlier versions). It receives control signals from the LOGO! base unit via a dedicated expansion bus connector.

• Outputs: It features 4 Relay Outputs, typically rated for switching $230\,\text{V AC}$ loads.

• Inputs: It also includes 4 Digital Inputs, allowing for additional status feedback or sensor connections to the main LOGO! unit.

• Power: It is a $230\,\text{V}$ AC powered module, which usually means it is designed to operate on the same voltage as the main LOGO! controller it is connected to.

Product Specifications

Product Advantages

• Output Flexibility (Relay Type): The use of relay outputs allows the module to switch both AC and DC loads and handle voltages up to $250\,\text{V AC}$, providing great flexibility compared to transistor outputs.

• Increased Capacity: It provides a simple and cost-effective way to significantly increase the I/O count of a standard LOGO! base unit, extending its application scope without needing a larger, more complex PLC.

• Integrated Inputs: The inclusion of 4 Digital Inputs alongside the outputs allows for collecting additional feedback or status signals from the field, making it an efficient I/O block.

• Simple Integration: It connects seamlessly to the LOGO! base module via a dedicated ribbon cable/expansion bus, requiring minimal configuration in the LOGO!Soft Comfort software.

• Compact Design: Its narrow, DIN-rail-mountable form factor saves space in small distribution cabinets and panels.

Precautions

• Voltage Compatibility: The 230R designation means this module is designed for $230\,\text{V AC}$ (or $115\,\text{V AC}$) power. Ensure the power supply matches the module and the connected LOGO! base unit. Mixing different voltage modules is generally not possible or recommended.

• Relay Switching Limits: Do not exceed the maximum rated switching current of $5\,\text{A}$ per output. For highly inductive loads (e.g., large motor contactors), use protection circuitry (snubber circuits or varistors) to prevent relay contact wear and premature failure.

• Wiring Standards: Adhere to local electrical codes and use appropriately sized wires for the loads being switched. Separate the high-voltage relay wiring from the low-voltage sensor wiring to prevent electrical noise.

• Software Configuration: The expanded I/O points must be correctly enabled and referenced in the main LOGO! program using the LOGO!Soft Comfort programming software.

• Load Type: For high-frequency switching or complex analog control, this relay module is less suitable than a dedicated transistor or analog output module.

Product Applications

The LOGO! Contact Module is typically used in small-scale automation and control tasks where the LOGO! logic module is the central controller.

• Small Pump Control Stations:

  • Switching on/off single-phase pumps or valves (using the relay outputs).

  • Monitoring float switches or pressure switches (using the digital inputs).

• Simple HVAC and Lighting Control:

  • Controlling contactors for lighting circuits in small buildings or rooms.

  • Switching small fans, humidifiers, or heater bands.

• Access and Gate Control:

  • Controlling motorized gates or barriers.

  • Monitoring limit switches or safety sensors.

• Machine Tool Control:

  • Managing low-power auxiliary functions or sequencing simple machine movements.
