How to choose a signal isolator
The isolator is located between the two system channels, so the choice of isolator must first determine the input and output functions, and at the same time, make the isolator input and output mode (voltage type, current type, loop power supply type, etc.) adapt to the front and rear channel connection 1:3 model. In addition, there are still many important parameters related to product performance, such as accuracy, power consumption, noise, insulation strength, and bus communication functions, such as: noise is related to accuracy, power consumption and heat are related to reliability, which require users to choose carefully. In short, applicability, reliability, and product cost-effectiveness are the main principles for choosing an isolator.
