Product Description
2.1
Function
This isolated barrier is used for intrinsic safety applications.
It transfers resistance values of RTDs or potentiometers from hazardous areas to safe areas.
The device supports 2-, 3-, or 4-wire technique 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.
The device is mounted on a 35 mm DIN mounting rail according to EN 60715.
