Siemens LOGO! DM16 230R Expansion Module (6ED1055-1FB10-0BA2)
Siemens LOGO! DM16 230R Expansion Module (6ED1055-1FB10-0BA2) is a digital I/O expansion module for LOGO! 8 controllers. Designed for 115/230 V AC/DC systems, it provides 8 digital inputs and 8 relay outputs, enabling reliable high-voltage I/O expansion for industrial and building automation applications across the UAE.
Product details
The Siemens LOGO! DM16 230R Expansion Module (6ED1055-1FB10-0BA2) is designed to expand the digital input and output capacity of Siemens LOGO! 8 basic units in automation systems operating directly on 115 V or 230 V AC/DC. This expansion module is well suited for applications where mains-voltage signal processing and relay-based switching are required without additional interface components.
The module offers 8 digital inputs compatible with AC and DC signals, along with 8 relay outputs for controlling high-voltage loads. The relay contacts support switching capacities of up to 5 A for resistive loads and 3 A for inductive loads, allowing direct control of lighting circuits, contactors, heaters, and industrial actuators.
Designed for seamless integration with LOGO! 8 controllers, the DM16 230R enables synchronized control logic and reliable signal handling across expanded automation architectures. Its compact DIN-rail form factor allows efficient use of space in control cabinets, making it suitable for both OEM panels and retrofit installations.
