Working Principles

The ISO120BG utilizes a differential input and output configuration along with an internal isolation barrier. The input signal is amplified and isolated from the output signal using a transformer or optical coupling. This ensures that any noise or high voltage transients present in the input signal do not affect the output signal.

Detailed Application Field Plans

The ISO120BG is commonly used in the following applications:

1. Industrial process control systems
2. Power monitoring and protection systems
3. Medical equipment
4. Isolated data acquisition systems
5. Motor control systems
