Overview
The Siemens 6ED1055-1FB10-0BA0 LOGO! DM16 230R expansion module extends the digital I/O capacity of LOGO! 8 mini controllers. This module provides 8 digital inputs and 8 relay-output contact points in a compact DIN rail form factor. With 230V AC supply compatibility and rated output current of 5A per relay contact, it is suited for small to mid-scale automation applications requiring additional I/O without replacing the core controller.
Key Features
- 8 digital inputs (DI) for sensor and switch signals
- 8 digital outputs (DO) with relay contacts, 5A per output
- Supply voltage: 230V AC (also supports 100–253V DC input)
- DIN rail mounting on 35 mm standard rail, 4 spacing units wide
- Operating temperature range: 0°C to +55°C ambient
- IP20 protection rating for industrial enclosures
- Drop-in compatible with Siemens LOGO! 8 controllers

Compatibility & Replacements
The Siemens 6ED1055-1FB10-0BA0 is designed exclusively for LOGO! 8 mini controllers and cannot be used with earlier LOGO! generations or other PLC platforms. A similar variant, the 6ED1055-1FB10-0BA2, is also available and shares identical electrical ratings. Always verify controller firmware and module compatibility before ordering replacement units. For system integration or substitution questions, consult Siemens documentation or contact our automation specialists.
