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
Each channel is capable of switching voltages up to ±48 VDC, 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 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).
