  • 114 channels of single pole, single throw (SPST) Form A relays
  • 0.5 A contact rating per channel
  • 78 pin D-sub connectors


The GX6338 is a low cost 6U switching card with 114 individual low level SPST Form A relays capable of switching 0.5 A at 200 VDC. The GX6338 is ideal for applications requiring high density switching.


The GX6338 consists of three groups: A, B, and C. Each group has 38 individual relays and a 78-pin D type connector. Each of the relays can be latched or unlatched under program control.

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.
