Siemens 6ED1055-1NB10-0BA2 Programmable Logic Controller Module

Siemens LOGO! DM16 24R expansion module (6ED1055-1NB10-0BA2) extends a LOGO! 8 controller with eight digital inputs and eight digital outputs, and includes a relay output on the first output. The IO operates at 24 V DC for sensing and actuation, and the module is powered through the LOGO! 8 base unit. It mounts on a 35 mm DIN rail, occupying four spacing units, and is designed to sit alongside the main LOGO! 8 module in a compact enclosure. The DM16 24R provides 8 DI and 8 DO, with the first DO channel implemented as a relay contact rated at 5 A at 24 V DC, enabling direct control of small loads without a separate relay module. This expansion is ideal for simple automated tasks such as turning sensors on/off, controlling lighting, driving small actuators, and building basic interlock sequences in hobbyist projects, small machines, or light production lines. Its 24 V DC IO compatibility and plug-in interface with LOGO! 8 deliver quick configuration with minimal wiring, making it a popular choice for expanding discrete IO without moving to a larger PLC system. Available from Siemens Industry Mall and authorized distributors under the 6ED1055-1NB10-0BA2 part number, this module is the DM16 24R expansion option for LOGO! 8, ensuring scalable IO as project requirements grow.
