Why Isolate?

Isolation Guide

Prevent Ground Loops

Ground loops occur when a circuit is grounded at multiple points, creating a path that can carry potentially harmful currents. By isolating signals between these points, you eliminate interference and protect your system.

Eliminate Common Mode Noise

Common mode noise happens when cabling picks up interference from high-energy devices like motors, variable-speed drives, or switches. This noise can distort or damage your signals. Isolating the signal ensures that even significant noise is effectively eliminated.

Ensure Plant Safety

In some cases, signals need to be sent to equipment, such as motors or variable speed drives, that are at high voltages relative to the ground. To protect both plant equipment and personnel, isolating sensors makes the system safer to work on. Keep in mind, however, that the side of the isolator connected to high-energy equipment remains unsafe.
