VTI introduces 100-V solid-state multiplexer

Irvine, CA. VTI Instruments has announced the release of its EX1200-3824, a high-speed solid-state multiplexer designed to provide flexible switching with eight banks of 1 x 24 one-wire multiplexers. This module is capable of accommodating over 3,000 one-wire switching channels in a 3U EX1208A mainframe. System integrators can also mix and match this module with other EX1200 plug-ins for even greater flexibility in switching and instrumentation subsystem design.

The solid-state design of the module delivers extremely fast switching speed and a near infinite life, making the EX1200-3824 suitable for test and automation applications in which relays are continuously switching.

With a 100-V input range, the module is suitable for applications such as automotive ECU testing in which signals capable of producing high-voltage transients are common. Since this module typically interfaces with data-acquisition instruments that are limited to 10-V input ranges, the EX1200-3824 offers the option of an on-board 10:1 attenuator to eliminate the need for external circuitry while ensuring maximum signal integrity.

The EX1200-3824 can be controlled programmatically using the supplied API, which is compliant to the industry-standard IVI Switch class definition. Both path level programming and individual relay control are available to simplify integration into test systems. On-board configuration relays are provided to connect the individual banks together, giving the system designer the flexibility to create test programs utilizing discrete 1 x 24s or configurations as large as 1 x 192 without external wiring.
