More Information

Overview Manuals I/O Flow Relay Loads Rail Fit Approvals

Features:

  • Four DC input points extend the connected LOGO! controller's field-state capacity.
  • Four relay contacts switch resistive or inductive loads within their separate documented limits.
  • The two-unit housing mounts directly on a 35 mm DIN rail.
Siemens 6ED1055-1MB00-0BA1 expands both the input and output sides of a LOGO! arrangement in one compact module.

The input circuits share the module's 12/24 V DC supply class, while the output section uses relay contacts rather than transistor outputs.

External fusing must remain part of the load circuit because the relay outputs do not include short-circuit protection.

The Siemens 6ED1055-1MB00-0BA1 LOGO! DM8 12/24R Digital Expansion Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Tracing signals through the expansion module

  • Input Side: Four DC field states enter the expansion module as separate digital inputs.
  • Module Bus: The LOGO! base module reads those expansion points through the internal module connection.
  • Output Side: Four commands operate isolated relay contacts rather than DC transistor channels.
  • Load Circuit: Each field load remains part of its own externally protected relay circuit.

Matching the contact path to the connected load

  • Resistive Loads: Resistive circuits use the higher documented contact-current limit.
  • Inductive Loads: Coils and other inductive loads use the lower contact-current boundary.
  • External Fuse: The field circuit must provide protection because the relay output is not short-circuit protected.
  • Relay Identity: The R suffix distinguishes this output hardware from transistor-output LOGO! expansion modules.

Placing the module in the LOGO! mounting row

  • Rail Standard: The enclosure clips onto a 35 mm DIN rail.
  • Row Width: Two spacing units must be available beside the connected LOGO! device.
  • Front Access: Input and relay terminals remain accessible from the front of the mounted module.
  • Enclosure Limit: IP20 protection requires the surrounding panel to provide the needed environmental barrier.

Reading the documented compliance coverage

  • North American Marks: CSA, UL, and FM approvals are listed for this module.
  • Control Standard: Development is identified with IEC 61131.
  • VDE Reference: The product data also cites VDE 0631.
  • Marine Use: Marine approval is included in the documented approval set.
Description
The Siemens LOGO! range uses 6ED1055-1MB00-0BA1 as a DM8 12/24R digital expansion module. It adds four DC input points and four relay output contacts to the I/O arrangement.

Power and input signals enter 6ED1055-1MB00-0BA1 through the 12/24 V DC side of the module. The permissible supply span covers both nominal levels while the four inputs remain DC signal channels.

At the output side, 6ED1055-1MB00-0BA1 switches loads through four relay contacts. The contacts are not short-circuit protected, so their documented resistive and inductive load limits remain tied to external circuit protection.

A two-spacing-unit enclosure places 6ED1055-1MB00-0BA1 on a 35 mm DIN rail. The IP20 module is documented for a 0 to 55 °C operating range and carries CSA, UL, FM, IEC 61131, VDE 0631, and marine approvals.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How can I distinguish 6ED1055-1MB00-0BA1 from a LOGO! DM8 230R module?
Siemens 6ED1055-1MB00-0BA1 is the DM8 12/24R version with a 12/24 V DC supply class; a 230R module has a different supply identity.
Do the relay outputs of 6ED1055-1MB00-0BA1 need external protection?
Yes. The four relay outputs on 6ED1055-1MB00-0BA1 are not short-circuit protected, so external fusing is required in the field load circuits.
How should inductive loads be checked for Siemens 6ED1055-1MB00-0BA1?
For 6ED1055-1MB00-0BA1, compare the load against the 3 A inductive-contact limit rather than applying the 5 A resistive figure.
Which side of 6ED1055-1MB00-0BA1 handles field states and which side switches loads?
The four DC inputs of 6ED1055-1MB00-0BA1 receive field states, while its four relay outputs make or break the separate load circuits.
What panel arrangement is required for 6ED1055-1MB00-0BA1?
Provide two spacing units on a 35 mm DIN rail for 6ED1055-1MB00-0BA1 and place the IP20 module inside an enclosure suitable for the installation.
