DNx-DIO-432, DNA-DIO-432, DNR-DIO-432, DNF-DIO-432

DNx-DIO-432 (Guardian series) boards are 32 channel, digital output boards. Each channel is configured as a current sink and switches voltages between 3.3 and 36 VDC. Each channel is rated for continuous operation at 600 mA with an output voltage drop of less than 550 mV. The DNx-DIO-432 is an ideal digital output interface in a wide variety of data acquisition and control applications.

As part of UEI's Guardian series, the DNx-DIO-432 not only controls the digital outputs, it also allows monitoring of each channel's output voltage and current. This allows the application to detect and flag short and open circuits as well as other "suspicious" behavior.

The Guardian advantage also includes programmable overcurrent protection. The user may select the current and duration of overload (as short as 10 mS) required before the channel is shut down. Each board provides 350 Vrms isolation and update rates to 1 kHz.

Each channel offers a pulse-width-modulated (PWM) "soft-start/stop" capability. This allows power to be applied/removed gradually, greatly increasing the reliability of devices like incandescent bulbs where thermal shock reduces life expectancy.
