The GX3104 is a precision 3U PXI module that forces and senses both voltage and current over a range of ±20 V and up to ± 1 A ( channel 1) with channels 2- 4 capable of supplying up to 500 mA per channel. Total available output current from the module is 1A.  The four channels are electrically isolated from the PXI power supply and share a common, isolated ground.
