United Electronic Industries (UEI) releases the Guardian DNA/DNR-DIO-432 and DNA/DNR-DIO-433 industrial digital-output boards for use with the company’s Ethernet-based PowerDNA, UEIPAC, UEILogger, and Modbus Cubes. DNR models are intended for UEI’s 12-slot rack-mount RACKtangle I/O chassis.
Each board provides 32 channels of digital output with up to 600 mA/channel of continuous current and an output voltage drop of less than 550 mV. Outputs on the DIO-432 versions are configured as current sources, while outputs on the DIO-433 versions are configured as current sinks. All output ports are configured as single 32-bit words. Maximum output throughput rate is 1 ksample/s. Guardian boards have an operating range of 3.3 VDC to 36 VDC.
As part of the Guardian design, the boards offer an input mode that monitors the output voltage and current of each channel and detects opens, shorts, and off-normal operation. This diagnostic function enables you to localize and correct faults quickly and accurately. In addition, channels not used as digital outputs can be used to measure 0 to 36-VDC analog voltage inputs with ±10-mV accuracy. Each channel also offers a pulse-width-modulated soft-start/stop feature that applies and removes power gradually, increasing the life and reliability of devices and components affected by thermal shock.
Software support for the boards is provided in the UEIDAQ Framework API. Framework provides a complete software interface to popular programming languages, operating systems, and data acquisition/control application packages, such as LabView, MATLAB/Simulink, and DASYLab.
The DNA-DIO-432 (current source) costs $1200; the DNR-DIO-432 (current source) costs $1350. The DNA-DIO-433 (current sink) costs $1200; the DNR-DIO-433 (current sink) costs $1350.
