Product description:

I. overview

YWD, YWE, YWL series DC transmitter system using the latest Hewlett-Packard Company device — HCNR200/201 linear optocoupler. The measured signal changes

For a voltage, the HCNR200/201 transform into a direct linear optocoupler and the measured signal into an excellent linear relationship and complete isolation voltage, then

Constant voltage (current) to output. This machine uses the computer aided design (CAD), has the principle is very simple, the line design is refined, the reliability is high,

Convenient installation and other advantages.

YWD, YWE, YWL series DC transmitter with its good performance and low price, can be widely used in telecommunications, electricity and other fields. Particularly suitable

For industrial process control.

Two, principle

The core components of the &mdash circuit; HCNR200/201 linear optocoupler consists of high-performance aluminum gallium arsenide light-emitting diode (LED) and two closely matched photodiodes

Constitution. The input of the photocell is used to control the intensity of the LED light and make it stable so that the nonlinear and unstable properties of LED are almost completely eliminated,

The output of the photocell produces a photocurrent that is linearly related to the intensity of light emitted by the LED. Due to the precise matching and careful design of the device

Plan, to ensure the linearity and stability of the optocoupler has gain very good.
