The DAP 840 has all of the features needed for an entry-level data acquisition or control application with light real-time processing, and provides all of the benefits of onboard intelligence. Contact us to find out how real-time processing can benefit your application.
The DAP 840/103
- has an onboard 486 processor
- comes with 8MB of DRAM onboard memory
- uses a PCI bus for PC-based platforms
- transfers data to PC at high rates – up to 800k samples per second
- allows real-time processing
- offers low latency – 0.2 ms task time quantum – for fast response
- increases sampling period resolution to 50 ns
- provides onboard emulation of DSP routines
- samples or updates the digital section at up to 800k values per second
- provides 14-bit A/D converter resolution
- samples analog inputs at up to 800k samples per second
- updates analog outputs at up to 400k samples per second each
- complies with the EMC Directive 89/336/EEC
There is one DAP 840 model: the DAP 840/103.
The DAP 840/103 model provides 14-bit A/D resolution for its 8 onboard analog inputs, and 12-bit D/A resolution for its 2 onboard analog outputs. The onboard analog input channels sample at an overall 800k samples per second, and the 8 onboard digital input channels sample at an overall rate of 800k words per second. The two onboard analog output channels each can run at 400k updates per second for an overall 800k updates per second, and the 8 onboard digital output channels update at an overall 800k words per second.
The DAP 840 cannot use expansion boards but does have limited Channel Architecture options.
The DAP 840 has a PCI host interface, and is capable of high speed data transfers to the host PC. Using bus mastering DMA transfers, the DAP840 can transfer data to the host PC at the maximum sampling rate of 800k samples per second.

* To maintain full 14-bit resolution may require a lower sample rate when sampling more than one channel per ADC.
** Top sampling speeds are available only with gain=1. Gains of 10, 100, and 500 are also available.
*** Disk logging and data transfer rates vary with PC platform.
