Introduction • 1
Introduction
JYTEK PXI-67921 is a relay multiplexer module which consists of 24 2-wire
relays (DPDT, 2 Form C). PXI-67921 provides 48x1 1-wire and 24x1 2-wire
and 12x1 4-wire configurations and typically connects one instrument, such
as a DMM, a digitizer or a signal source, with many points which need
measurement or excitation.
Relays of PXI-67921 can be updated by either direct-update mode or auto-
scan mode. The latter mode supports scanlist of 1k-sample for
deterministic scanning.
PXI trigger functions are fully supported and software programmable. The
multiple switch modules can be synchronized and triggered without additional
field wiring.
For safety critical applications, PXI-67921 module can switch to the preset
state by either asserting emergency shutdown manually, or watchdog timer
overflow event.
