GSB-01/02 Scanner Box

The GSB-01 and GSB-02 Scanner Boxes are multiplex switching accessories that expand the channel capacity of GW Instek GPT-9800, GPT-9900, and GPT-9900A series safety testers. By routing test signals to multiple DUT connection points, the scanner boxes enable automated multi-point withstanding voltage, insulation resistance, and ground bond testing without manual probe repositioning. Up to four scanner boxes can connect to a single GPT unit, providing 32 test channels.

Model Comparison

Applications

Production lines manufacturing electrical appliances, medical devices, power supplies, and industrial equipment use the GSB scanner boxes to automate multi-point safety testing. The GSB-01 provides 8 high-voltage channels for withstanding voltage and insulation resistance tests across multiple insulation barriers in a single test sequence. The GSB-02 adds 2 dedicated ground bond channels for products requiring protective earth continuity verification alongside dielectric testing.

High-intensity LED indicators on each channel display real-time switching status and pass/fail judgment, giving operators immediate visual feedback during automated test sequences. Front and rear input connector design allows flexible fixture wiring arrangements for different production line layouts.

GSAS Micro Systems provides the GSB Scanner Boxes in India with integration support for safety test systems and compatibility guidance for GPT-series testers.
