J-Testr Supply Breakout Card
The Supply Breakout card gives independent access to both Supply A and Supply B via ‘easy to use’ 4-way screw terminal blocks. Each Supply block also contains the supply sense lines immediately adjacent to its supply output terminal.
By default the sense measurement is attached to the supply positive, for the positive sense, and common ground, for the negative sense using a zero-ohm 0805 SMT links. For remote sensing these links can be easily removed and the sensing made via the screw terminals.
The system fixed supplies are taken to a separate 4-way screw terminal block with a single common ground connection. Care must always be taken not to overload these system supplies as this would blow the internal 2A supply fuse.
The Supply Breakout card UserIO (GPIO) lines are taken to eight clearly marked 1mm diameter test-point holes. The card also contains 3 extra common grounding points.
Warning: This card can be used with the Isolated power supply card but the negative terminal will be shorted to Common Ground.
