SunYuan OFS Series Fiber optic signal to analog isolated transmitter: OFS P-O-Q, is a kind of high-tech low cost long-distance transmission fiber optic isolated transmitter designed and developed by Sunyuan Technology. It can be used together with Sunyuan OFS U(A)-P-Q module to get standard 4-20mA or 0-10V analog signal after isolated transmission and amplification via optical fiber. The isolated transmitter realizes sensor signal, PLC, DCS analog signal high speed non-distorted long-distance transmission.
SunYuan OFS P-O-Q module is designed by using DC-DC isolation power module, analog amplification and conversion circuit, fiber optic isolated control circuit, etc. It mainly applied to convert fiber optic signal into analog signal DA conversion. It also applied in remote data acquisition and control on MCU, CAN BUS, Ethernet, PLC/DCS Host machine system and sensors, meters signal. The internal wide range DC-DC isolation power module provides power supply to internal output conditioning circuit, DA conversion circuit and output signal
isolated circuit. The SMD technique and new isolation measures used enable the module withstand 3000VDC isolation among input, output, power supply and meets the standard required in high low temperature, humidity, vibration, etc severe environment.
SunYuan OFS P-O-Q Series module is easy to use. It realized fiber optic to analog signal isolated
transmission without any external components. The module is designed with DIN35 standard DIN Rail-mounted package and widely used in mining, oil chemistry, electric devices, medical equipment, industrial automatic, new energy facility, etc fields, user can select it based on the actual conditions.
