DNR-DIO-452
12-Channel Electromechanical Relay Output Layer
 
The DNA/DNR-DIO-452 are 12-channel, electromechanical relay boards for use with “Cube” and RACKtangle® I/O series respsectively. The DIO-452 boards are designed for use in a wide variety of switching and digital control applications. Each channel is configured as a standard Form C (SPDT) relay and switches voltages up to 100 VDC or 150 VAC. Each channel is rated for continuous operation at 2 Amps @ 30 VDC and 0.75 Amp at 125 VAC with an output voltage of less than 200 mV (<200 mOhm).

All relays default to “off” on power up/reset. Switching rates up to 125 Hz are supported. Each relay is protected by an on-board 2 Amp slow-blow fuse.

All connections are made through a convenient 37-pin D connector ensuring no problems obtaining mating cables or connectors. Users may also connect the DNx-DIO-452 boards to our popular DNA-STP-37 screw terminal panel via the DNA-CBL-37S cables. The cables are fully shielded and are available in 1, 3, 10 and 20 foot lengths. 

The DNx-DIO-452 series includes software drivers supporting all popular operating systems including: Windows, Linux, QNX, VXWorks, RTX, and other popular Real-Time Operating Systems. Windows users may take advantage or the powerful UEIDAQ Framework which provides a simple and complete software interface to all popular Windows programming languages and data acquisition and control applications (e.g. LabVIEW, DASYLab, MATLAB).
