Multi-channel control circuit for real-time control of events in Aditya tokamak

•Low cost microcontroller based control circuit.•The control hardware can be programmed/configured very easily for different applications.•Microcontroller programming is done in assembly language so that precise timing can be achieved with micro seconds resolution.•Successful implementation of this circuit in noisy tokamak environment.•Efficient noise and burst elimination.•Can be integrated in to the other subsystems.•Low cost solution for implementing feedback control in small and medium size tokamaks and other experiments requiring feedback control.
