DNx-MF-101, DNA-MF-101, DNR-MF-101, DNF-MF-101

The DNA/DNR/DNF-MF-101 are multifunction analog and digital I/O boards for use in UEI’s Cube/RACKtangle/FLATRACK I/O chassis respectively. The board offers a powerful combination of I/O including 16 single-ended/8 differential analog inputs, 2 analog outputs, 20 bits of digital I/O, one I2C port, and one RS-232/422/485 port.

The board offers 8 software selectable A/D ranges from ±80V to ±0.156V with 18-bit resolution. The ±80 Volt range makes the DNx-MF-101 an ideal measurement solution in a host of automotive, aerospace, and power generation applications where many DAQ products’ 10 volts maximum input range cannot be used without external signal conditioning. The “high voltage” and “low voltage” configurations are programmable on a per-channel basis. Programmable gains combined with the board’s 18-bit A/D converter provides resolution as low as 1.19 microvolts. The DNx-MF-101 provides sample rates as high as 2000 sample per second on each channel (16 k/s aggregate). Two ±10 voltage or current (e.g. 4-20 mA) 16-bit analog outputs are also provided.

The board offers 20 bits of digital input/output broken into 16 bits of industrial voltages where each bit may be independently set as input or output. Four bits of TTL level DIO are also provided (programmed as I/O in banks of two). Industrial inputs and outputs have a wide operating range from 3.3V to 55 VDC. The industrial range (not logic-level) inputs have programmable pull up/down resistors that allow inputs to monitor contacts connected to a supply voltage or ground. Inputs are sensed with an 200 kHz A/D converter so high and low voltage thresholds are programmable and allowing change of state detection with 5 µs resolution. The industrial range (not logic-level) 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) or can act as a simple switch to Vcc or Gnd. Industrial digital outputs can also be configured as flexible controllers with PWM and 16-bit pulse width resolution or softstart. The PWM/softstart parameters are selectable on a per-channel basis. The outputs are protected with 1.25 Amp fast-blow fuses.
