United Electronic Industries (UEI) has released the DNx-MF-102, a multifunctional analog and digital I/O board that is compatible with all of the company’s I/O chassis systems.
The board offers a powerful combination of 34 analog and digital I/O channels combined with two CAN ports and one RS-232/422/485 port. The highly flexible board is ideal for real-time data acquisition (DAQ), test, control and other critical aerospace and defense applications that require the interfacing of multiple signals.
The DNx-MF-102 is engineered to manage a wide range of input and output signals. The board provides 16 channels of 8 software-selectable A/D ranges, spanning from ±80 V to ±0.156 V, with an 18-bit resolution. The ±80 V range makes the DNx-MF-102 an ideal measurement solution for aerospace and power generation applications, where many DAQ products with a 10 V maximum input range would require external signal conditioning. The “high voltage” and “low voltage” configurations are programmable on a per-channel basis.
The board features 16 bits of industrial voltage DIO, with each bit independently configurable as either an input or output. These DIO bits support a broad operating range from 3.3V to 55 VDC. The digital inputs include programmable pull-up/down resistors, enabling them to monitor contacts connected to either a supply voltage or ground. An A/D converter senses the inputs, allowing programmable high and low voltage thresholds and facilitating change-of-state detection with a 5 μs resolution. The digital outputs can be configured as current sourcing (a switch between Vcc and the output), current sinking (a switch between Gnd and the output), push-pull (connecting to Vcc or Gnd, but not simultaneously), or as a simple switch to Vcc or Gnd.
The board includes three communications ports. The first is an RS-232/422/485 that can be set for any baud rate from 300 baud to 2 Mbaud with 0.01% frequency accuracy. The board also offers two CAN 2.0 ports which support Standard, Fast and Fast+ baud rates, as well as ARINC-825.
The DNx-MF-102 is supported by a complete software suite including support for Windows, Linux and all popular RTOS, as well as support for programming languages and DAQ applications including LabVIEW and MATLAB. All UEI PowerDNA products are also backed by UEI’s 10-year availability guarantee and a standard 3-year hardware warranty, with the ability to extend up to 10-years to mitigate obsolescence issues.
