The DNA/DNR/DNF-DIO-480 are universal digital I/O boards for use in UEI’s Cube/RACKtangle/FLATRACK I/O chassis respectively. The board offers 32 independently configureable DIO channels that can be set as input our output, and are compatible with everything from 3.3V TTL levels to 55 V industrial signal levels.

Each of the 32-bits may be independently set as input or output. When configured as inputs, the logic level thresholds may be set with 275 mV resolution to 55 V.

The inputs have programmable pull up/down resistors that allow inputs to monitor contacts connected to a supply voltage or ground. Inputs are sensed with a 100 kHz A/D converter so high and low voltage thresholds are programmable and allow change of state detection with 10 μs resolution. Digital input data may be streamed at 100 kHz, and to ensure no lost data the DIO-480 provides a 32-bit by 4096 FIFO. The digital input data may be streamed to FIFOs with timestamps which are generated at the start of the scan.

The outputs can be set as current sourcing (a switch between Vcc and the output), current sinking (a switch between Gnd and the output), push-pull (connect to Vcc or Gnd but not at the same time). The digital outputs can also be configured as flexible controller switch PWM and 16-bit pulse width resolution with soft-start. The PWM/soft-start parameters are selectable on a per-channel basis. The outputs are protected with 1.25 Amp fast-blow fuses. A software controlled "circuit breaker" can be enabled to monitor and trip the switch at ~750 mA.

The board is supported by a variety of cable and screw terminal options certain to meet the needs of almost all users. For those wishing to create their own cables, all connections are through a standard 62-pin “D” connector allowing OEM users to build custom cabling systems with standard, readily available components.

The DNx-DIO-480 is supported by a complete software “suite” including support for Windows, Linux and all popular RTOS. Windows support is provided by the UEIDAQ Framework which includes a powerful software interface to Windows programming languages and DAQ applications including VISTAS, LabVIEW and MATLAB. An extensive factory written software suite is also provided for all popular “non-Windows” operating systems including Linux, VXworks, QNX, RTX, INtime and more. All software support includes extensive example programs that make it easy to cut-and-paste the I/O software into your applications.
