Multiplexer Switch Handles High Voltages

Capable of switching up to 1,000 Vdc/Vac and rated for one million operations at a 60W load, Model 1260-132 DPST dry reed relay multiplexer is useful for high-voltage DMM measurements and high-voltage signal distribution in telecomm, medical equipment, and general switching applications. Designed for use in either the Adapt-a-Switch 1260-100, VXI carrier, or the 1256, GPIB/RS-232 Switching Mainframe, the multiplexer switch’s plug-in design achieves rapid switch card expansion and replacement, while the easily-configured relays facilitate user-specific test configurations. The 1260-132 plug-in contains a 1x23 two-wire multiplexer comprised of two Form A reed relays. A multiplexer isolation relay is included on each card, reducing the channel capacitance when multiple 1260-132s are cascaded to build very large multiplexers. Model 1260-132 includes drivers for LabWindows/CVI and LabVIEW for VXI and GPIB applications. It is programmable via GPIB commands when used with the 1256 switching system. Price is $1,300.
