Fusion.IO is DDI’s state-of-the-art I/O platform delivering real-time EtherCAT control of central and remote I/O. The Fusion.IO platform supports centralized, or blended central & remote I/O arrays. Fusion.IO safe I/O controllers are equipped with four RIM expansion ports enabling real-time direct control of remote I/O at distances up to 250ft. Fusion.IO technology delivers best-in-class features at a lower cost to deploy, and with a lower cost of ownership.
Fast and Deterministic Machine Control: 8 KHz EtherCAT I/O
Built-in Functional Safety: Fusion IO is TÜV certified for SIL 3 functional safety
Cost Effective: Configurable I/O mix – pay only for the I/O you need, and add when needed
Machine Design Flexibility: Enable centralized and distributed controls
- Customizable: Customer selects the I/O slot-card mix, and system interface (Field Connect) designed to accept the customers preferred cabling scheme
Faster Time-to-Market: Program complex interlock schemes with DDI’s software utility – Interlock BuilderTM

Trusted Partner: Backed by the most committed team in the industry
Expansion Ports: Add up to 4 remote I/O modules (RIMs) to your safety I/O system
Versatile: Add DIO, AIO, temperature sensing and even RS232/RS485 serial communication to your EtherCAT network

Fusion IO Controller Platform
Centralized I/O Control with Expansion Capability
Fusion IO is a turn-key solution merging real-time I/O control, intrinsic SIL3 functional safety and direct control of remote I/O into a powerful, cost effective solution. DDI’s Fusion IO control platform answers the needs of designers of the most demanding, mission critical automation and process equipment worldwide.
Fusion.IO incorporates a real-time EtherCAT network interface enabling direct control of remote I/O by adding a Remote Interface Module (RIM) to one of its four remote I/O expansion (RIM) ports.
