Resistor & relay cards feature a 0.25-2Ω resolution
PCI and PXI programmable resistor and relay cards, which feature 12 resistor channel options, a resolution of 0.25-2Ω and channel counts of either two or four, have been released by Pickering Interfaces. To extend the resistance range within a test system, the 50-294 PCI card and the 40-294 PXI card are optionally available with eight SPST relays.
The modules, which feature an accuracy of ±1%, remove the need for additional switching products within a test system. To ensure long service life and fast setting times, each card uses high quality instrument grade reed relays.
