The Isolation Amplifier DK 8000 is used for isolation and conversion of customer-specific industrial signals.

When it comes to individualized solutions, the know-how advantage of our development team stands ready to serve. This allows us to offer customer-specific solutions with the proverbial DRAGO quality in the shortest possible time; solutions which, as a result of individualized consultation, optimally meet all customer needs, including their economic ones.

The slim housing with 12.5 mm width saves space in the switch cabinet and facilitates by the practical plug-in screw terminal blocks the assembly.

The new universal power pack for 20 to 253 V AC/DC means the DK 8000 can be used anywhere in the world, with all mains power supplies. The unit’s high efficiency contributes significantly to reducing the unit’s own heat generation. This is reflected in extremely high reliability and long-term stability.
