Pickering Interfaces has introduced the 60-191 LXI high current & sense SPST switching family for automated test systems that require programmable distribution and sequencing of multiple high-current power supplies. The 4U LXI units switch signals up to 80 A and 300 V, combine up to twenty 40 A and four 80 A hermetically sealed SPST-NO contactors with 1 A SPST sense-line relays, and support standard front-panel screw-terminal connections. Each unit includes a sequencing service for up to 5,000 predefined switching sequences, 1000Base-T Ethernet control, IVI and direct I/O drivers for Windows and Linux and support for LabVIEW, Python, C/C++, C#, MATLAB and Simulink.
