1) Isolator : Prevents current ground loops

Current ground loop may occur when the 2 devices are wired in series, and also negative sides of both 2 devices are grounding. This makes incorrect signal flow to either of devices.
In this case, you can prevent current ground loop by signal isolation between the sensor and the device by using isolator.

2) Isolator : Protection from external noise

When the sensor is not isolated and caused the failure, it may affects the connected devices such as Meter/PLC etc. It will make a big problem such as the factory line stop and lowering quality caused by the failure or malfunction.
To prevent the above problems, it is important to isolate using Isolator between the sensor and devices.

3) Isolator : Clarify the boundary of responsibility

Currently there are various sensors and devices, and those manufacturers are common to be several companies.
Isolator clarifies the boundary of responsibility by isolation between each devices (between the companies) when the failure occurs. This makes easier to solve the problem.

4) Isolator : Signal boosting to increase load resistance

If the load resistance of sensor output (4 to 20mAdc) is small, connecting an isolator between the sensor and the device can be used to increase the load resistance to the value of isolator output.
This makes it possible to connect the output signals from the sensors to several devices.
