Siemens 6ED1055-1NB10-0BA2 LOGO! 8 DM16 24R Expansion Module 8DI/8DO Relay

The Siemens 6ED1055-1NB10-0BA2 is a LOGO! 8 DM16 24R expansion module adding 8 digital inputs and 8 relay outputs to a LOGO! base unit, rated 24V DC in and 5A per relay output. It mounts on a 35mm DIN rail, occupies 4 module-width spacing units, and switches loads up to 1000W lamp or 3A inductive per contact.

Selection Notes

The 5A relay-rated outputs on this DM16 24R handle direct contactor coils and small motor loads that a transistor-output expansion module couldn't switch without an interposing relay — pick the transistor variant instead where fast, high-cycle switching matters more than raw current capacity. Occupying 4 spacing units for 8DI/8DO, it adds a full input-and-output block in one slot on the DIN rail rather than splitting inputs and outputs across two smaller modules.

Applications

Expands a LOGO! 8 base unit's I/O count for small automation tasks — building services, pump/lighting control, and simple machine interlocks needing relay-switched outputs on 24V DC.
