Siemens 6ED1055-1CB10-0BA2 LOGO! 8 DM16 24 8DI/8DO 24V DC Logic Module

The Siemens LOGO! DM16 24 (6ED1055-1CB10-0BA2) is a digital expansion module for the LOGO! 8 logic module platform, adding 8 digital inputs and 8 digital outputs on a 24V DC supply. It mounts on a 35mm DIN rail and occupies 4 spacing units, extending I/O count for LOGO! 8 base units without adding a second logic controller.

Selection Notes

The DM16 24 runs on a 24V DC input rail and switches transistor outputs rated 0.3A each, so it fits sensor and low-power actuator I/O such as PLC-class relays, indicator lamps, and small solenoids rather than direct motor switching. Pick this all-digital 8DI/8DO variant over analog or relay-output LOGO! expansion modules when the application needs additional transistor-switched digital points on an existing LOGO! 8 base unit without installing a second logic controller. The 10 Hz resistive / 0.5 Hz inductive switching-frequency limits also rule it out for high-cycle-rate switching duty.

Applications

Used to extend I/O on LOGO! 8-based control panels for HVAC equipment, small conveyor or pump skids, lighting control, and building-services automation where the base LOGO! 8 module's onboard I/O count is insufficient.
