Function and Positioning

The 3DM455.60-240 functions as the central mainboard and expansion hub in compact industrial control systems, integrating logic control, native high‑speed I/O, and large‑scale expansion capabilities. It executes user programs, manages system resources, and processes 8 fast input signals from sensors/encoders while driving 8 high‑power outputs for actuators. Via the SYSTEM 2005 backplane bus, it expands up to 240 I/O points by connecting additional I/O modules, enabling flexible system scaling. Positioned as an all‑in‑one mainboard solution, it eliminates the need for separate CPU and basic I/O modules, simplifying system design, reducing cabinet space, and lowering overall costs for small‑to‑medium automation projects.
