DIRECT CURRENT INSTRUMENT CONVERTERS

The converter consists of a set of precision resistors in a plastic housing. The external surface of the housing has terminals and connectors for input and output signals.

Converters are used as external current collectors for controllers and for hot redundancy of controllers, they are designed for installation in explosive rooms, in secondary equipment cabinets.
