Enhanced Fusion platform extends distributed I/O communications to 100 meters and strengthens power-interruption immunity, EMC performance, and onboard diagnostics

Scotts Valley, CA – September 3, 2026

Digital Dynamics, Inc. (DDI), a leading provider of embedded control and I/O solutions for semiconductor and display manufacturing equipment, today announced that Fusion 1.1 has received TÜV certification demonstrating compliance with the requirements of SIL3 (IEC 61508) and Cat.3/PL e (ISO 13849-1).

Fusion 1.1 is an enhanced release of DDI’s flagship Fusion platform, which has gained broad adoption across the wafer fabrication equipment (WFE) and display fabrication equipment (DFE) industries. The release expands Fusion’s distributed I/O capabilities while strengthening power resilience, electromagnetic compatibility, and diagnostic visibility.

Key Fusion 1.1 enhancements include:

• DDI Bus extended up to 100 meters: DDI’s patented, safety-rated communication link connects the Fusion controller directly to Remote I/O Modules (RIMs) located on fab equipment or remote equipment—including equipment in the sub-fab—enabling SIL 3-compliant distributed I/O architectures over greater distances.
• Enhanced power-interruption immunity: Fusion 1.1 complies with IEC 61000-4-29 and has demonstrated uninterrupted operation during power interruptions of up to 5 milliseconds, helping maintain control continuity during brief supply disturbances.
• Integrated supply-voltage monitoring: Fusion 1.1 continuously monitors input-supply voltage. Out-of-range events are timestamped and recorded for retrieval through Fusion Onboard Diagnostics (FOBD), helping equipment manufacturers identify intermittent power conditions and accelerate troubleshooting.
• Improved EMC immunity: Fusion 1.1 complies with IEC 61000-4-2 and has demonstrated immunity to electrostatic discharge of up to 8, enhancing robustness in electrically demanding equipment environments.

“Fusion 1.1 strengthens the capabilities equipment manufacturers need to build safer, more reliable, and more serviceable systems,” said Nir Merry, Chairman and CEO of Digital Dynamics. “By combining TÜV-certified functional safety, extended distributed I/O connectivity, integrated control of up to 64 temperature zones, enhanced power immunity, and onboard diagnostic intelligence, Fusion provides a robust control platform for the industry’s most demanding applications.”

Fusion integrates control, functional safety, distributed I/O, and advanced diagnostics into a scalable platform designed for semiconductor and display fabrication equipment.
