Group3 Control
Group3 Technology's primary business is the design and manufacture of electronic equipment of two types, scientific instruments for measuring magnetic fields and specialist control systems.
Group3 Control is designed for scientific and industrial applications and in particular high voltage particle accelerator control.
A card plugged into the control computer communicates by fibre optic cables with a series of small modules which house the I/O boards. Each module is populated with the I/O boards required at that point, and placed close to the controlled apparatus. The fibre optic cable traverses any voltage and distance, providing noise free, high speed communications.
Very high channel density per computer slot can be achieved with 3 I/O boards per module and 16 modules per fibre loop.
