Measurement Computing PCI-DDA04/12 Analog Output Board

  • Provides Four Channels of 12-Bit Analog Output and 48 Bits of Digital I/O
  • D/A Converters Independently Configurable for Bipolar or Unipolar
  • Software Selectable Settings


The Measurement Computing PCI-DDA04/12 provides four channels of 12-bit analog output and 48 bits of digital I/O.

The D/A converters can be independently configured for either Bipolar or Unipolar. Bipolar ranges are ±10V, ±5V, and ±2.5V. Unipolar ranges are 0 to 10V, 0 to 5V, and 0 to 2.5V. The outputs may be updated individually or simultaneously. The range settings are software-selectable.

The digital I/O ports are configured as two 82C55 mode 0 emulations. Each group is divided into three 8-bit ports: Port A, Port B, and Port C. Port C can be split into two four-bit ports: Port C-HI and Port C-LO. Each of these ports may be individually programmed as input or output. The digital outputs are capable of sinking 64mA and sourcing 15mA utilizing standard "S" logic.

The PCI interface uses the PLX 9052 chip, which is a slave-only device. The PCI interface for the analog output is configured in a 16-bit, multiplexed address/data bus, I/O access mode. The PCI interface for the digital I/O is configured in an 8-bit, multiplexed address/data bus, I/O access mode to be register-compatible with the PCI-DIO48H and PCI-DIO96H boards.

The PCI-DDA04/12 board is completely plug-and-play, with no jumpers or switches to set. All board addresses are set by the board's plug-and-play software. Board configuration is controlled by your system's BIOS.

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
