PRODUCT DESCRIPTION
Eight relay outputs for multi-circuit LOGO! control
Siemens 6ED1055-1FB10-0BA2 is a LOGO! DM16 230R digital expansion with eight inputs and eight relay outputs. It extends a compatible LOGO! 8 base module for nominal 115/230 V AC/DC installations requiring additional discrete control circuits.
Its 71.5 × 90 × 58 mm housing occupies four module widths. The eight input terminals form two groups of four for phase assignment; the relay circuits require external protection and load checks against the resistive, inductive and switching-frequency limits.

ACTUAL APPLICATIONS
Where 6ED1055-1FB10-0BA2 fits in compact automation
Siemens LOGO! application examples inform these system-level uses. The expansion module adds I/O; the base program, wiring and connected loads require separate validation.
-
01 · ZONE CONTROL
Additional lighting commands in a sports hall
Siemens lists sports-hall lighting as a LOGO! application. The DM16 relay channels can extend independently protected zone commands; lighting-driver characteristics and switching equipment remain part of the system design. -
02 · SHUTTER SEQUENCING
Direction commands and end-position feedback
The Siemens shutter-control example provides a basis for allocating additional direction commands and limit-switch signals. Use appropriate external motor switching and interlocking, with each relay circuit checked for its assigned duty. -
03 · VENTILATION STAGES
Step selection for fan equipment
For the LOGO! fan-step control application described by Siemens, additional relay contacts can select stages through properly rated external devices. Validate the sequence and prohibit conflicting stage commands in the engineered control arrangement.

Manuals & support
LOGO! 8 DIGITAL EXPANSION
Coordinate eight relay circuits with the base program
6ED1055-1FB10-0BA2 adds eight input and eight output points through the LOGO! expansion interface. In the DM16 230R, I1–I4 and I5–I8 form separate input groups; inputs within each group must share the same phase.
Relay outputs provide electrically isolated switching contacts. Check each circuit separately against the load category: the documented limit is 5 A resistive or 3 A inductive, with no integral short-circuit protection.
Energize the expansion before or together with the base module. Confirm the intended I/O mapping in the LOGO! project and test all assigned channels before releasing the controlled equipment to operation.
Features:
- Exact Siemens order code: 6ED1055-1FB10-0BA2
- LOGO! DM16 230R with 8 DI and 8 relay outputs
- Validate both four-input groups and eight load circuits
The Siemens 6ED1055-1FB10-0BA2 LOGO! DM16 230R requires its supply, terminal assignment and base-module arrangement to be checked before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Use the full 6ED1055-1FB10-0BA2 identity for the LOGO! DM16 230R replacement. Retain a record of channel functions, terminal markings and the installed position in the expansion chain.
Review the relay duty before reusing the existing load design. Mechanical switching capability does not equal the permitted frequency under load; resistive and inductive applications have different limits.
After isolated replacement, restore the approved supply sequence and prove each input and output against the drawing. Verify external interlocks and protection independently of the standard LOGO! control program.
Features:
- Match the complete 6ED1055-1FB10-0BA2 order code
- Two input-group phase assignments
- Individual relay loads and protective devices
The Siemens 6ED1055-1FB10-0BA2 LOGO! DM16 230R requires replacement verification of electrical ratings, expansion order, field wiring and the base-module project before commissioning.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 6ED1055-1FB10-0BA2
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Can an AC-powered base be combined with a DC-powered DM16 230R?
Siemens requires 230 V LOGO! base and digital expansion modules to use the same supply type. Match AC with AC or DC with DC, and observe the specified phase or polarity relationship before connection. -
Is a 4 A inductive load acceptable because it is below the 5 A contact figure?
No. The documented inductive-load limit is 3 A; the 5 A value applies to resistive loads. Select an external switching device if the actual inductive duty exceeds the contact rating. -
Are the contacts intended for a very small milliamp-level signal?
The exact datasheet specifies a minimum switching load of 100 mA, and the manual states its recommended low-load application conditions. Do not assume reliable dry-circuit performance for a much smaller signal. -
Can the relays switch a powered load at the listed 10 Hz mechanical rate?
No. The manual distinguishes mechanical operation from loaded switching: the maximum is 2 Hz for resistive or lamp loads and 0.5 Hz for inductive loads. Design the actual duty around the applicable loaded rating. -
Will a short input pulse be detected as soon as voltage crosses the threshold?
Not necessarily. The exact datasheet lists maximum input delays of 40 ms for a rising transition and 75 ms for a falling transition. Validate pulse duration together with program scan and the complete signal path. -
Does a shorted output load trip built-in electronic protection?
No integral output short-circuit protection is specified for this relay module. Select external protection for each circuit using the Siemens guidance and the actual wiring and load ratings. -
When should the DM16 supply turn on relative to the base supply?
Siemens instructs that expansion power be applied before or simultaneously with the base supply. Include this sequence in the panel power-up design so the expansion can be detected correctly. -
What channel-level acceptance test should an integrator record after replacement?
Against the approved I/O drawing, exercise all eight input indications and verify each of the eight output commands reaches its intended load. Record the mapping, external interlock response and restored operating sequence before equipment handover.
