In order to achieve both the signal condition remote control and the work statute self-check through Ethemet, a distributed signal condition (DSC) system has been developed for control and data acquisition (CODAC) in the EAST tokamak nuclear fusion experiment. Based on differential amplifiers, analog multiplexers and the embedded Ethernet communication technology, a DSC system is designed and produced. This paper summarizes the DSC system design, and presents a kind of calibration method for it. This DSC system has been integrated into the EAST CODAC system, and used successfully in the 2008 EAST experiments. The user-friendly, high performance, and cost-effective DSC system greatly improves the work efficiency and reduces the fault rates of the CODAC system.
