Siemens LOGO! DM16 24R Expansion Module (6ED1055-1NB10-0BA2)
Siemens LOGO! DM16 24R Expansion Module (6ED1055-1NB10-0BA2) is a digital I/O expansion module for LOGO! 8 controllers. Operating on 24 V AC/DC, it provides 8 digital inputs and 8 relay outputs, enabling reliable relay-based I/O expansion for industrial and building automation systems across the UAE.
Product details
The Siemens LOGO! DM16 24R Expansion Module (6ED1055-1NB10-0BA2) reminder expands the digital input and output capacity of Siemens LOGO! 8 basic units in 24 V AC/DC automation systems. This module is intended for applications where relay-based switching is required for controlling loads directly from the controller.
The module is equipped with 8 digital inputs for processing field signals and 8 relay outputs suitable for switching both resistive and inductive loads. With relay switching capacity up to 5 A (resistive) and 3 A (inductive), the DM16 24R allows direct control of contactors, lighting circuits, solenoid valves, and industrial actuators without additional interface relays.
Designed for seamless integration with LOGO! 8 controllers, the DM16 24R ensures synchronized signal processing and stable operation across expanded automation architectures. Its compact DIN-rail mounting design supports efficient panel layout and simplifies expansion in both new installations and retrofit projects.
