ruida RDLC320-A laser engraving controller

Ruida RDLC320-A is a laser-cutting controller. It is used to control and manage the operations of a laser-cutting machine. The controller receives commands from a computer and sends signals to the laser cutting machine’s components to execute the desired actions, such as cutting or engraving on a material.

Ruida RDLC320-A is based on high-performance floating 32-bit DSP+FPGA architecture. The co2 laser cutter controller can complete large-scale complex motion control algorithms to achieve continuous path control and position control of multi-axis motion, as well as energy tracking control to maintain laser energy balance at any speed point. Large-scale logic gate array FPGA can complete complex communication protocols and flexible IO expansion. Communication transfer speed is fast and easy to operate.
