In Part 2 of our Understanding Signal Isolators, Converters, and Interfaces series, we explain the key differences between 4-wire (line-powered) isolators and 2-wire (loop-powered) isolators used in industrial process control. Learn how signal isolator power architecture impacts accuracy, reliability, load capability, and installation, including support for 4–20 mA loops, voltage outputs, bipolar signals, and long cable runs. This video covers ground loops, signal isolation, loop power limitations, and how to choose the right isolator for real-world applications in automation, instrumentation, and control systems.
