Product Description
Product Overview Product overview
The LYG-...1 series signal isolator is an intelligent instrument designed with anti-interference and signal transformation/distribution capabilities. At its core, it employs either electromagnetic or optoelectronic isolation technology to separate input and output signals, ensuring that the electrical potential reference point of the input signal (input ground) remains independent from the output signal’s reference point (output ground). This effectively suppresses common-ground loop interference commonly found in automated control systems and breaks the conductive path of interfering signals, significantly enhancing the system's overall immunity to noise. Additionally, the device can proportionally transform the input signal, delivering one or multiple user-defined electrical signals as required. It is widely used across various industrial control environments.
