NPGL series intelligent isolatorPerformance Overview:
Input single or dual current or voltage signals, transmit isolated single or dual linear current or voltage signals, and improve the electrical isolation performance between input, output, and power supply.
Technical features:
This product adopts advanced digital technology and has excellent performance in suppressing high and low frequency interference signals. Even in high-power variable frequency control systems, it can still be reliably applied. Internally, it adopts many advanced technologies such as digital calibration, zero free and full potentiometer, automatic dynamic zero calibration, temperature drift automatic compensation, etc., and meets the electromagnetic interference requirements of Class IV (harsh industrial site) environment specified in IEC61000-4-4:1995. The application of this series of technologies ensures the stability and reliability of the product scientifically.
The above technologies are leading the international advanced level.
Applicability:
It can be used in conjunction with unit combination instruments and DCS, PLC and other systems, and has a wide range of applications in major projects in industries such as oil fields, petrochemicals, manufacturing, power, metallurgy, etc.
Technical parameters:
System transmission accuracy: ± 0.2% × F · S
Temperature drift: ≤ 0.005%F·S/℃
Working temperature: Industrial standard -10~+55 ℃
