Technology

Centurion electrical control system

The Centurion electrical control system utilizes standard industry protocols, while still providing a platform that is scalable for future advancements.

Intelligent sensors and I/O devices monitor and control the dragline, enabling machine health and reporting, as well as performance enhancement systems
Advanced communication and monitoring links to both your mine management and your maintenance crew reduce downtime
Centurion-based graphic user interface in the operator cab and machinery house provide continuous feedback on all operating systems, empowering your operators to pursue peak performance from the dragline
Uses finger-safe 24VDC for maximized operator safety
Distributed I/O drops and fibre-optic cable linking drives work with a supervisory controller to reduce wiring, resulting in fewer potential points of failure and simplified troubleshooting
