Overview
The National Instruments PXI-2584 is a high-voltage multiplexer
switch in a single-slot, 3U PXI module. With a CAT II certification at
300 V, it is capable of routing general-purpose ATE loads or high-voltage,
low-current signals. The 600 V CAT I channel-to-ground isolation on the
NI PXI-2584 makes it ideal for fuel cell and battery stack applications.
You also can use the module in multimodule configurations for taking
measurements on hundreds of channels. The CAT I and CAT II safety
ratings combined with UL safety certification make it ideally suited for
high-voltage ATE systems that include the NI PXI-4071 1000 V digital
multimeter. The reed relays in the PXI-2584 also ensure longer
lifetimes and faster actuation times for test equipment.
Interleaved Topology for
Maximum Channel Count
Interleaved topology is a method to increase channel count when
measuring potentials that are on a stack such as battery stacks and fuel
cell stacks. In traditional 2-wire topologies, each channel would put two
wires across each component under test, which would limit the PXI-2584
to six differential channels. By putting each single input pin on the front
connector at points in between potentials on a stack, the channel count
is extended from six to 11 2-wire channels. In addition to maximizing
channel count on a module, the topology offers a free “straddle”
channel when testing battery stacks over multiple modules.
