    Tips: What is an analog signal isolator?

    An analog signal isolator is a device designed to electrically separate and protect analog signals transmitted between two components or systems. The primary purpose of an analog signal isolator is to prevent unwanted electrical interactions, such as ground loops and interference, that can affect the accuracy and reliability of analog signals.

    Analog signal isolators typically work by using techniques such as transformers or optocouplers to create an electrical barrier between the input and output sides. The input signal is converted into an isolated signal, allowing it to be transmitted to the output side without a direct electrical connection. This isolation helps in applications where different parts of a system operate at different potentials or where there's a need to protect sensitive equipment from potential damage caused by electrical disturbances.

    Analog signal isolators are commonly used in industrial automation, process control, and other applications where precise and interference-free transmission of analog signals is critical.
