Applications

Professional uses based on the published module architecture

Compact machine control

Adds four DC inputs and four relay outputs to a LOGO! 8 controller where mixed-voltage switching is required.

Building services

Suitable for pumps, fans, lighting circuits and other actuators that benefit from electrically isolated relay contacts.

Panel expansion

Two-module-wide DIN-rail construction supports space-efficient I/O growth without changing the basic LOGO! program architecture.

Applications

Inputs & Outputs

Channel design and signal behavior for this exact variant

Four digital inputs

The DC inputs accept 12/24 V field signals, with a defined signal-1 threshold above 8.5 V and typical 1.5 ms response.

Four relay outputs

Each output is electrically isolated and rated up to 5 A, allowing direct control of many resistive and inductive loads within the published limits.

Output protection

External protection is required because relay outputs are not short-circuit proof; parallel operation for current increase is not permitted.

Inputs & Outputs

Electrical Data

Power, timing and load characteristics

Wide DC range

The module operates from 10.8 to 28.8 V DC and includes reverse-polarity protection.

Load switching

Relay contacts are rated to 240 V AC/DC, with a recommended minimum load of 100 mA at 12 V AC/DC.

Timing

Maximum signal frequency is 4 Hz on standard inputs; output switching rates depend on the connected load type.

Electrical Data

Installation

Mechanical, wiring and compatibility considerations

Mechanical

Mount on a 35 mm DIN rail using two LOGO! spacing units. Maintain ventilation and wiring clearances specified for the enclosure.

Wiring

Separate input, relay-output and supply conductors according to voltage class. Use suitable overcurrent protection for the relay circuits.

Compatibility

Use with LOGO! 8 basic devices. Verify the complete order number and the 12/24R electrical variant before commissioning.

Installation

Product FAQ

Six model-specific procurement and engineering checks

1. How can I verify that the quotation covers the exact 6ED1055-1MB00-0BA2?

Require the quotation, product label and packing label to show the complete order number 6ED1055-1MB00-0BA2. Cross-check the official description and 12/24 V DC supply, four DC inputs, four 5 A relay outputs and 35.5 x 90 x 58 mm dimensions.

2. How can New, Used and Refurbished units be distinguished?

Request current photographs of the product label, terminals, housing, DIN-rail latch and factory packaging. New units should not show wiring marks, tool damage, oxidation, repaired terminals or replaced identification labels.

3. How should the supplier be verified?

Confirm the supplier's legal company identity, business address, payment beneficiary and industrial automation sales history. Ask for a written quotation that identifies Siemens, the complete model, condition, quantity and traceable contact information.

4. Which engineering details must be checked before purchase?

Verify 12/24 V DC supply, four DC inputs, four 5 A relay outputs and 35.5 x 90 x 58 mm dimensions. The selected LOGO! 8 basic module, field wiring, load type, enclosure protection and environmental limits must also match the project.

5. What physical evidence should be requested before payment?

Ask for dated photographs or video showing the complete 6ED1055-1MB00-0BA2 label, serial or production code, terminals, accessories, packaging and a single-frame view linking the unit to the supplier's quotation.

6. Can another LOGO! expansion-module suffix replace this model?

Not automatically. A DM8 24 transistor-output or DM8 230R module changes the supply and output technology and is not a drop-in substitute. Any alternative must be approved against the electrical design and LOGO! 8 compatibility requirements.
