The GX6377 3U PXI multi function switch card provides users with the ability to switch both high current and general-purpose signals using only one 3U PXI switch module. The card features multiple channels of high current switching capability for 10 A and 2 A applications as well as two, 16 x 2 switch matrix groups, which can also be configured as a 32 x 2 or 16 x 4 matrix.


The GX6377 offers a total of 3 high current, independent relays — five 10 A, Form A; four 2 A, Form A; and four 2 A, Form C. The dual 16 x 2 relay matrix is rated for 500 mA and is hardware configurable as a 16 x 4 matrix or software configurable as a 32 x 2 matrix.

Programming and Software

The board is supplied with the GXSW library, a software package that includes a virtual instrument panel, and a Windows 32/64-bit DLL driver library and documentation. The virtual panel can be used to interactively program and control the instrument from a window that displays the instrument’s current settings and status. In addition, interface files are provided to support access to programming tools and languages such as ATEasy, LabView, LabView/Real-Time, C/C++, Microsoft Visual Basic®, Delphi, and Pascal. An On-Line help file and PDF User's Guide provides documentation that includes instructions for installing, using and programming the board.
A separate software package - GtLinux - provides support for Linux 32/64 operating systems.
