Vibstar Vibration Controller
Best Solution for the Control of Vibrator
The Vibstar vibration controller is designed with the highest performance of floating-point DSP processor from U.S. TI Company. It gives highly reliable performance, by combining low-noise analog technology with 24bit high-precision module/digital conversion technology.
In addition, the Vibstar vibration controller can realize dependable interactive communication by adoption of a network interface and a computer. Its hardware comes with 8 synchronous input channels, one control output channel, and one COLA output channel. The software of our control equipment can offer multiple functions such as random, sine, classic shock, RSTD, sine on random, and the random on random. Our product is the optimum solution for the vibrator control system.
