Isolation

What is a signal isolator?

A signal isolator or signal converter is a signal conditioning device used to interface process signals with other devices. Signal isolators ensure a stable and accurate signal output by offering superior resistance to electro-magnetic interference. They are also capable of converting and amplifying the process signals for improved performance and compatibility. PR electronics offers a range of isolators with superior performance and low power consumption.
