34.Analog signal to frequency signal (VF/IF conversion) isolation transmitter: ISO U(A)-P-F series
- SunYuan DC voltage signal (DIN 1X1 ISO U-P-F) or current signal (DIN 1X1 ISO A-P-F) VF converter is an isolation transmitter isolation amplifier that converts analog isolation into corresponding digital pulse frequency signals.The isolation transmitter has built-in multiple groups of high-isolation DC/DC distributed power supplies, which respectively supply power for the internal input end amplifier circuit, modulation circuit, output end demodulation circuit, conversion circuit, and filter circuit. At the same time, it also supplies power to several high-performance Signal isolation, AD conversion, linearization compensation, interference suppression circuit, etc.The signal input and output circuits, and the auxiliary power circuit are equipped with multiple protection devices such as TVS tubes, PPTC resettable fuses, and two-way suppression diodes. The products have been inspected and corrected before they leave the factory, and users can use them directly.The SMD process structure and new technology isolation measures enable the device to achieve: 3000VDC three isolation for power supply and signal input/output. And it can meet the harsh working environment requirements of industrial grade wide temperature, humidity, vibration and other on-site. DIN 35 rail-mounted 1-input&2-output, 2-input&2-output analog signal to frequency VF isolation converter, which is mainly composed of ISO series analog signal to frequency signal (V/F conversion) isolation transmitter IC.The ISO U(A)-P-F integrated module is very convenient to use. Customers only need to connect the zero point and full-scale potentiometer for calibration to realize the isolation and transmission of the sensor analog signal and convert it into a unit pulse signal.The product can be made according to user-defined parameter requirements, and the installation method is standard SIP 16Pin PCB board welding installation or DIN 35 rail installation. Especially suitable for frequency modulation and phase modulation, analog-to-digital AD converters, GPRS/GMS wireless data transmission, digital voltmeters, data measuring instruments and remote telemetry and remote control equipment.
Analog to Frequency (VF Conversion / IF Conversion) Isolated Transmitters: ISO U(A)-P-F Series
The SunYuan ISO-U(A)-P-F Isolation Transmitter is a hybrid integrated circuit that isolates and converts an analog DC voltage signal or current signal into a corresponding digital pulse frequency signal. The circuit integrates several groups of highly isolated DC/DC distributed power supplies on the same chip, respectively supplying power to the internal input amplifier circuits, modulator circuits and output demodulator circuits, converter circuits, filter circuits, as well as supplying power to several high-performance signal isolation, AD converter, linearization compensation, and interference suppression circuits. SMD process structure and new technology isolation measures make the device can achieve: power supply, signal input / output 3000VDC triple isolation. And can meet the industrial grade wide temperature, humidity, vibration and other harsh working environment requirements.
ISO series analog signal to frequency signal (V/F conversion) isolation transmitter IC is very easy to use, with the customer only need to external zero, fullness potentiometer calibration can be realized sensor analog signal isolation into the unit pulse signal isolation transmission. The product can be made according to the user's customized parameter requirements, and the mounting method is standard SIP 16Pin PCB board welding mounting or DIN 35 rail mounting. Especially suitable for FM and phase control, analog-to-digital AD converter, GPRS/GMS wireless digital transmission, digital voltmeter, data measurement instruments and remote telemetry remote control equipment.
