There is one current DAP 5216a model: the DAP 5216a/627.
All a-Series Data Acquisition Processor boards – including the DAP 5216a – share the same cabling and Eurocards for termination and expansion.
The DAP 5216a has a PCI host interface, and is capable of high speed data transfers to the host PC. Using bus mastering DMA transfers, the DAP 5216a can transfer data to the host PC at the maximum sampling rate of 2M samples per second.
The DAP 5216a provides 16-bit A/D resolution for its 16 onboard analog inputs, and 16-bit D/A resolution for its 2 onboard analog outputs. The onboard analog input channels sample at an overall 500k samples per second, and the 16 onboard digital input channels sample at an overall rate of 2M words per second. The two onboard analog output channels update at an overall 2M updates per second, and the 16 onboard digital output channels update at an overall 2M words per second.
Through the onboard DAPL operating system, users of the DAP5216a can adjust the task scheduling interval – down to a 0.1 ms task time quantum. This means that a single task will run for no more than 0.1 ms before DAPL switches to another task. In process control applications, the system must respond to data as quickly as possible; a system with a 0.1 task time interval attends to each task regularly... and quickly.
DAP 5216a
The DAP 5216a model adds 16-bit resolution to the proven capabilities of the DAP 5200a line. It has the same real-time processing power as the DAP 5200a. Real-time processing functions include smoothing, filtering, FFT, PID control, and responding to alarm conditions; the DAP 5216a also can scan high-speed data for trigger events in real time to capture pre-trigger as well as post-trigger data.
The DAP 5216a
