商品説明
The PD2 DIO Series is no longer available. Please see the OMB-DAQBOARD-2000 Series as a substitute or contact Sales/Data Acquistion Engineering.
For applications that involve a high number of digital I/O lines, Omega offers two models in the PD2-DIO family with either 64 or 128 I/O lines. Instead of following the industry trend of implementing discrete I/O with cumbersome and limiting 8255-type devices, we work with 16-bit line drivers under control of a DSP and custom logic. As a result, you no longer need to create external circuitry to guarantee power-on startup states; our software allows you to configure startup states in groups of 16-bit ports. You no longer need to design separate interrupt circuitry; our hardware comes with four high-speed interrupts waiting for you to use. The digital I/O lines are protected against electrostatic discharge and automatically detect shorts on power up. Besides digital I/O, the board features three 24-bit counter/timers as well as two high-speed ESSI (Enhanced Synchronous Serial Interface) ports. The onboard DSP and optimized PCI-bus interface also allow the card to optionally stream digital data to or from disk at rates as high as 2 MB/S. Distribution panels make all the board's I/O capabilities available for field connection. Further, an optional accessory (PD2-DIO-CONN64- 4) distributes 64 of the digital I/O points into four sets of 16 lines through industry-standard 50- pin IDC connectors. They, in turn, attach directly to relay panels available from UEI and many other sources.
