The 40-521-021 is a 1-pole 24x8 high density matrix. Typical applications include signal routing in Functional ATE and data acquisition systems. These PXI matrix cards are constructed using high reliability ruthenium electro-plated reed relays, offering >10e8 operations to give maximum switching confidence with long life and stable contact resistance. Larger matrices may be constructed by daisy chaining the common signals from multiple PXI modulesles. However, for applications that require a very large matrix, Pickering s BRIC modules are best suited. All 40-521 series modules are fitted with reed relays (ruthenium sputtered type), these offer very long life with good low level switching performance and excellent contact resistance stability. Spare Reed Relays are built onto the circuit board to allow easy maintenance with minimum downtime.
