The R4103 is an 8 channel, 40 A relay card with integrated parallel current measurement for all channels.
The card provides 8 inputs for the DUT (Device-Under-Test). Those can be connected to HC1-8 (HC – High Current Bus) or switched to the 8 outputs of the card for an external load box.
Furthermore, any channel of the DUT , single or parallel, can be connected with a power supply (HC9 and HC10) or with an electronic load (HC11 and HC12).
The integrated 8 channel current measurement module has an accuracy of 0.2% with a resolution of 5 mA. 1 A is the smallest current measurable.
The card must be calibrated every 12 month.
