SMX4030, 4032 Series PXI Relay Scanners / Multiplexers

Description:

The SMX4030 Series are the only switching modules for PXI/CompactPCI specifically designed for measurements. They feature 35-channel relay-switching that is designed for use in applications requiring precision signal switching. The switching module is controlled with high-level commands to its on-board controller. The controller simplifies programming and minimizes the overhead typical and book-keeping associated with other switching modules. It also simplifies on the fly configuration of 2-Wire, 4-Wire, and 6-Wire switching applications. The very low thermal EMF and noise of the SMX4032 are a must for very accurate measurements of resistance or precise voltages, and for testing various sensors and transducers. Each of the relays can be automatically routed using pre-defined configurations, or controlled individually. All switching actions are performed within a single actuation time of less than 5 milliseconds.

The SMX4030 is an economical PXI/cPCI Switching Module, yet it has lower noise than other similar products for measurement applications. The SMX4032 adds isolated structure, and super-low thermal EMFs, a must for resistance measurements. It is designed for more demanding applications requiring lower noise and higher precision.

For manual operation, or system verification, the provided GUI of the SMX4030 appears on your PC monitor. All relays are depicted on this virtual front panel, with additional control functions in the top menu. You can control these instruments without needing any programming, however it is supplied with a SDK to allow for configuration using TestPoint, ATEasy, Matlab, VisualBasic, LabView®, LabWindows/CVI®, C++, Delphi or other software packages under windows or Linux.

For ease of use, three optional modules are available. The standard Screw Terminal Block is the SMX40, the Screw Terminal Block with Isothermal structure and block temperature sensor for use with Thermocouples is the SMX40T, and the loopback test module is the SM40L.
