34、ISO U(A)-P-F Series Analog to Frequency (VF Converter/IF Converter) Isolated Transmitters
An isolation transmitter isolation amplifier that isolates and converts analog quantities into corresponding digital pulse frequency signals. The isolation transmitter built-in a number of highly isolated DC/DC distribution power supply, respectively, to the internal input amplification circuit, modulation circuit and the output demodulation circuit, conversion circuit, filtering circuit power supply, but also power supply to several high-performance signal isolation, AD conversion, linearization compensation, interference suppression circuit. In the signal input and output circuits, auxiliary power supply circuits configured with TVS tubes, PPTC self-recovery fuse, two-way suppression diodes and other multi-protection devices, the product has been inspected and corrected before shipment, the user can be used directly.SMD process structure and new technology isolation measures to enable 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 U(A)-P-F integrated module is very convenient to use, with the customer only need to external zero, fullness potentiometer for calibration can be realized sensor analog signal isolation into unit pulse signal isolation transmission. Products can be customized according to the user's parameter requirements for the production, installation for the standard SIP 16Pin PCB board welding installation 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.
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.
