Isolators are a kind of linear optical coupling isolation principle that output and convert the input signal. The input, output and working power supply are isolated from each other. Isolator, also known as signal isolator, is an significant part of industrial control system. Isolators have many advantages, such as anti-interference and low power consumption. Power consumption refers to the electrical energy consumed when the isolator is working. It relates to the calorific value of the product at work. This parameter is closely associated with the service life, reliability, appearance and installation mode of the isolator. WINSOURCE’s isolators are all low-power-consumed products.
