Function
This isolated barrier is used for intrinsic safety applications.
It transfers resistance values of RTDs or potentiometers from hazardous areas to safe areas.
A 2-, 3-, or 4-wire technique is available depending on the required accuracy.
The input card of the control system measures the same load as if it were connected directly to the resistance in a hazardous area.
