Introduction • 1
Introduction
JYTEK PXI-67931 is a matrix module with 32 cross-point 2-wire relays (DPDT, 2 Form
C). The default configuration of the PXI-67931 is a 4-group 2x4 2-wire matrix. With
the termination board, TB-6231, users can flexibly choose one of the configurations:
one 4x8, two 4x4, one 2x16, two 2x8, and four 2x4. Any contact of the
PXI-67931 can connect to other contacts at the same bank, individually, or in
combination. The PXI-67931 matrix module simplifies wiring and makes it easy to
change the internal connection path.
The contact position of the relays can be changed either by direct software
commands or by following the instructions previously stored in the on-board scan
list. The scan list advances upon the trigger from external measurement devices,
such as a DMM. The scan list can also advance when the scan-delay timer expires. PXI
trigger functions are supported and software programmable. Multiple modules can be
synchronized without additional field wiring.
