The DNR-MUX-418 provides 18 independent one-by-three switches for use with UEI’s popular RACKtangle chassis (it is not available for UEI’sCube or DNF series chassis. The DNA/DNF-MUX-414 are 14-channel versions available for Cubes/FlatRACKs.) The MUX-418 boards are designed for use in a wide variety of switching and digital control applications and in particular making connections is SIL applications.Each channel provides a “common” terminal connected to three independent SPST (Form A) contacts. In a typical SIL application, this allows each flight computer signal to be connected to the actual trainer, a simulated device, a third test or error signal, or left open to simulate a broken wire or other open circuit condition.
Each channel is capable of switching voltages up to ±48 VDC or AC waveforms with peaks less than ±48 VDC or sinusoidal signals up to 34 Vrms. Each channel is rated for continuous operation at 1 A DC or AC rms with a switch resistance of less than 0.2 Ohm (typical, not including external cables). All relays default to “open” on power up/reset.Switching rates up to 250 Hz are supported and all channels default to break-before-make relay operation. Each board provides 350 VDC isolation between channels, as well as between the board, cube and other installed I/O boards.
All connections are made through a convenient 78-pin D connector ensuring no problems obtaining mating cables or connectors. Users may also connect the DNx-MUX-418 boards to our popular DNA-STP-78 screw terminal panel via the DNA-CBL-78 cables. The cables are fully shielded and are available in 3 and 10 foot lengths.
The DNx-MUX-418 series includes software drivers supporting all popular operating systems including: Windows, Linux, QNX, VXWorks,RTX, and other popular Real-Time Operating Systems. Windows users may use the UEIDAQ Framework which provides a simple and complete software interface to all popular Windows programming languages and data acquisition and control applications (e.g. LabVIEW, MATLAB)
Engineers know that application development requires extensive testing. UEI's multiplexer switch interfaces provide a straight-forward solution for routing signals, simulated signals, and faults for testing your UUT.
UEI Director of Business Development Bob Judd describes the latest generation of SIL/HIL/ and Hybrid-Test-Bench products and how they help you, the system designer build a powerful, efficient and price-effective solution.
