The 40–500 from Pickering Interfaces is a 64 x 4 solid state switching matrix with the capability of hot switching voltages up to 60 V. The matrix can sustain inrush currents of 1.5 A for 100 ms and continuously carry 0.5 A on each cross-point switch. The Y axis of the matrix is designed to support 3 A continuous current, allowing each Y axis to be connected to multiple X connections carrying high currents on each cross-point. The 40–500 is suitable for handling AC or DC signals and occupies one 3U PXI slot. It uses a robust 78 way D type connector for user connections.
Use of solid state switching ensures a very long service life, potentially infinite operations, even when hot switching large voltages and currents, including those with high inrush currents because of capacitive loading of the signal path – a condition that can lead to early failures in mechanical relays applications include power supply routing in test systems and the routing of high current signals where the test system requires frequent hot switching events. The solid state switching matrix can be supported in any PXI chassis or can be supported in an LXI environment using the company’s 60–100 A modular switching chassis.
