Signametrics SMX4030, SMX4032, SMU4030, SMU4032 PXI and USB Relay Switches

The Signametrics 4032 and 4030 models offer a superior functionality and performance, at unmatched prices. These flexible relay switching modules are designed for applications requiring both, performance and ease of use. They can be reconfigured on-the-fly as 35:1 differential or set to 16 channel 4-Wire multiplexers. Several other pre-set configurations are also available. For ultimate flexibility, the universal configuration provides control over each of the relays, independently.

Often ignored is the error contribution of the switching subsystem. Using the wrong switch can result in errors several orders of magnitude greater than expected. Employing an Instrumentation type 4032 model will have negligible signal degradation. Expect the general purpose 4030 model to perform 10 times better than most other USB and PXI switches.

Built-in intelligence relives the host CPU, facilitating for high level commands. The benefit is a much simplified programming and speed. i.e., to multiplex a set of 4-Wire resistors, issue a configuration command to set it as a 4-Wire mux, and a command to select a channel. All currently closed channel relays will open and the selected two channel relays corresponding to the 4-Wire connection will close. All is done within a single actuation time. It is possible to efficiently mix devices requiring different configurations, without sacrificing channels. The number of channels per system is unlimited.

For Thermocouple (TC) multiplexing use the optional SMX40T Isothermal block. The SMX40T active temperature sensor provides the cold junction temperature sensor, required for Thermocouple measurements. The low thermal EMF of the 4032 minimizes temperature error. Digital Multimeters such as the 2060 and 2064 from Signametrics include linearization for various TC types. As with the Signametrics DMMs, these units carry a 30 day no-risk trial period.

The software package included is complete, and does not require any additional drivers or packages. It is not in Signametrics interest to constrain users to a short list of S/W packages. Therefore the type of driver provided is universal. It allows these Switches to be controlled by a large number of software environments, including MS Word, Excel, Mat Lab, Visual Basic, C, C++, C#, LabWindows, LabView, ATEasy, Delphi and may other graphical and text based software packages. An added benefit of having no dependencies makes for a fast and easy installation and operation. In less than five minutes you will be controlling these switches.
