General Description:
Jie ShengDa Technology JSD OI-Bx-Px-V(I)Ox Series Pressure-strain bridge isolation amplifier is a Hybrid integrated circuit by witch the differential signal Proportionally isolate amplifier, convert into DC signal output , The pressure-strain bridge isolation amplifier IC provides a set of efficient micro-power voltage reference source to the pressure sensor , and output an international standard current (voltage) signal ,The chip integrates a set of multi-channel high-isolation DC/DC micro power supply and several high-performance signal isolation converter to supply for the internal amplifier circuit, its four-port isolation(input, power supply, output and power distribution),and the isolation voltage between them is up to 3000VDC, JSD OI-Bx-Px-V(I)Ox series Isolation Amplifiers has strong anti-electromagnetic EMC interference capability, Isolation amplifier using a photoelectric isolation technology, compared to the magnetic isolation transform EMC appliance strong anti-interference and high anti-frequency signal space electromagnetic interference products widely used in electrical, instrumentation, medical equipment, weighing instruments, industrial automation and other industries fields.
JSD OI-Bx-Px-V(I)Ox series isolation amplifier products have PCB board soldering and standard DIN 35 rail mounting, rail mounting can achieve analog 1-input-1-output, the user simply by wiring can be used.
Product very easy to use, just add a 50KΩ multi-turn potentiometer ADJ correction, you can achieve signal isolation, transmission and transformation capabilities, and to achieve long-term signals without distortion transmission. The product simplifies the user's design, greatly improves the PCB board space utilization.
