SunYuan OFS Series Fiber Optic Interface Signal to Analog High Precision Isolation Transmitter：OFS P-O-Q is a newly developed industry-leading technology of SunYuan technology signal ultra-long-distance transmission of low-cost fiber-optic signal isolation transmitter. Can be paired with the OFS U(A)-P-Q module produced by Shunyuan Technology, the fiber optic transmission of signals through the isolation and amplification of the signal reduction into a standard 4-20mA or 0-10V analog signals to achieve the industrial field sensors, PLC, DCS in the analog signal transmission at high speed and without distortion.

    SunYuan OFS P-O-Q products are integrated with DC-DC isolated power supply, analog amplifier and converter circuits, fiber-optic signal isolation control circuits, etc. in the same module, which is used for the DA reduction occasions that need to isolate fiber-optic signals into analog signals at industrial sites. It is suitable for remote acquisition, analysis and precision control of all kinds of instruments, sensors and transmitters signals by control systems such as MCU control, fieldbus, Ethernet/IoT, PLC/DCS upper computer. Internal integrated wide range DC-DC isolated power supply, respectively to the internal output conditioning circuit, DA conversion circuit and output signal isolation circuit power supply. SMD process structure and new technology isolation measures so that the device can achieve: signal input and auxiliary power supply, output signal 3000VDC triple isolation. And can meet the industrial grade wide temperature, humidity, vibration of the site of the harsh working environment requirements.

     SunYuan OFS P-O-Q series products are very easy to use, without any external components to achieve the fiber optic interface signal conversion to analog signal isolation and transmission function. The product adopts DIN35 standard rail mounting (or metal box) method, widely used in metallurgy and mining, petrochemical, electric power equipment, medical instruments, industrial automation, new energy facilities and military scientific research and other fields, the user can choose the appropriate product according to the needs of the site.
