BU 04-i from SPS-ELECTR
The BU 04-i is a high-current switch for grounding, also called ground bond or protective earth. It is used as an additional contact option on SPS electronic CO-series test adapters, such as CO 20 and CO 21.
In practice, it provides a robust connection when working with test probe connections or ground control in a test setup. It is part of the modular CO-series, which is designed for use with the BA 18 basic adapter. This means that the setup can be adapted to the specific task instead of replacing the entire workstation.
The solution is developed for environments where test adapters are used repeatedly and where wearing parts can be replaced separately. In this way, the BU 04-i fits in as part of a flexible design for professional testing and measurement.
