DNx-MUX-414, DNA-MUX-414, DNR-MUX-414, DNF-MUX-414

The DNR/DNF/DNA-MUX-414 provides 14 independent one-by-three switches for use with UEI’s RACKtangle, FlatRACK and Cube chassis respectively. The MUX-414 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, AC waveforms with peaks less than ±48 VDC or sinusoidal signals up to 34Vrms. Each channel is rated for continuous operation at 1 A DC or ACrms 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 62-pin D connector ensuring no problems obtaining mating cables or connectors. Users may also connect the DNx-MUX-414 boards to our popular DNA-STP-62 screw terminal panel via the DNA-CBL-62 cables. The cables are fully shielded and are available in 1, 3, 6, 10 and 20 foot lengths.

The DNx-MUX-414 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).
