        This series of devices adopts large-scale FPGA design and unique technology, which can simultaneously support 1-8 channels of analog signals (current/voltage), 4 serial ports, and 8 switch signals to fiber optic relays. This device adopts dual power supply, high-performance FPGA programmable devices, no MCU processing, high-speed conversion, sampling frequency can reach 20KHZ, and a 12 bit AD conversion chip. The effective communication distance can reach 0-120KM, and the communication rate of the serial port can reach 0-115-2KBPS.

Due to the use of optical fiber as the transmission medium, it can completely avoid the threats of lightning, surges, electromagnetic interference, etc. to communication equipment in harsh environments. At the same time, it eliminates the investment in lightning surge protection equipment when using copper wire, greatly improving the reliability, safety, and confidentiality of control signals. At the same time, it also solves the problem of limited cable transmission distance, with a maximum communication distance of 2-120KM.
