Applications

Professional uses based on the published module architecture

24 V DC automation

Adds four sensor inputs and four solid-state outputs to compact LOGO! 8 machine and process control panels.

Frequent switching

Transistor outputs avoid mechanical contact wear and suit valves, indicators and interface relays within the 0.3 A channel rating.

Distributed panel functions

A two-module DIN-rail footprint supports local I/O expansion while retaining LOGO! 8 programming and diagnostics.

Inputs & Outputs

Channel design and signal behavior for this exact variant

Four digital inputs

The inputs use 24 V DC logic, with signal 0 below 5 V, signal 1 above 12 V and typical 1.5 ms delay.

Four transistor outputs

Current-sourcing channels provide up to 0.3 A each and can directly drive suitable 24 V DC loads.

Electronic protection

Outputs are short-circuit and overload protected. Parallel connection for increased current is not permitted.

Electrical Data

Power, timing and load characteristics

Supply tolerance

The permissible supply range is 20.4 to 28.8 V DC with reverse-polarity protection.

Output behavior

Maximum output voltage follows the supply voltage; current limitation is approximately 1 A per channel.

Switching performance

Electrical and resistive-load switching is specified up to 10 Hz, while inductive loads are limited to 0.5 Hz.

Installation

Mechanical, wiring and compatibility considerations

Mechanical

Install on a 35 mm DIN rail. The module occupies two LOGO! spacing units and measures 35.5 x 90 x 58 mm.

Wiring

Use 24 V DC field devices and size conductors and protection for the combined channel current and connected loads.

Compatibility

The module is intended for LOGO! 8 basic devices. Confirm the transistor-output suffix 1CB00-0BA2 before wiring.

FAQ

Product FAQ

Six model-specific procurement and engineering checks

1. How can I verify that the quotation covers the exact 6ED1055-1CB00-0BA2?

Require the quotation, product label and packing label to show the complete order number 6ED1055-1CB00-0BA2. Cross-check the official description and 24 V DC supply, four DC inputs, four 0.3 A transistor outputs and short-circuit protection.

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 24 V DC supply, four DC inputs, four 0.3 A transistor outputs and short-circuit protection. 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 6ED1055-1CB00-0BA2 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. Relay-output DM8 variants change electrical isolation, switching capacity and load behavior and must not be substituted without redesign. Any alternative must be approved against the electrical design and LOGO! 8 compatibility requirements.
