DT330 Series

Low-Cost Analog Output and Digital
I/O Boards for the PCI BusOverview
The DT330 Series is a family of four low-cost analog
output and digital I/O boards for the PCI bus. Ideal for
applications requiring multiple D/A outputs and control
capabilities, the DT330 Series offers four or eight analog
outputs as well as 32 digital I/O lines.

Key Features• Four different board configurations provide a range

DT330 Series boards feature either 4 or 8 channels and 32
digital I/O lines.

of flexible, cost-effective options.

• Four or eight analog outputs with 12- or 16-bit

The DT331 and DT332 have 12-bit analog outputs thatcan be set through software for ranges of ±10 V, 0–10 V,±5 V, or 0–5 V. The DT333 and DT334 have 16-bit analog
outputs with a fixed range of ±10 V.

resolution.
• 32 digital I/O lines for non-clocked monitoring orcontrol of high channel count applications.
• Interrupt on bit change detection for monitoring
critical signals.

32 Digital I/O Channels for High-ChannelCount Requirements

Supported Operating Systems• Windows® 10/8/7/Vista®/XP 32/64-bit

Each DT330 Series board provides 32 digital I/O lines,
grouped into four 8-bit ports. You can program each port
for either input or output. Digital outputs are capable ofdriving solid-state relays (sink 24 mA and source 15 mA).

Analog Outputs Provide Flexibility
Available with four or eight analog outputs at 12- or
16‑bit resolution, the DT330 Series analog outputs can beupdated through programmed I/O at slow speeds (actualspeed depends on the PC – typical update rate: 1 kS/s to10 kS/s).

The DT330 Series boards can generate an interrupt when
any of the eight digital I/O lines corresponding to one ofthe 8-bit digital ports changes state. This feature is usefulwhen you want to monitor critical signals or when youwant to signal the host computer to transfer data to orfrom the board. You can enable the interrupts on a bitby-bit basis on this port.

Ordering Summary

All signals are brought out to a dedicated 68-pin connector on the backplateof the DT330 Series board. The STP68 screw terminal panel is available tosimplify connections. The EP305 cable connects the DT330 Series board tothe STP68 screw terminal panel.

Cross-Series Compatibility
Virtually all Data Translation data acquisition boards and modules arecompatible with the DT-Open Layers® Class Library. This means that if
your application was developed with one of Data Translation’s software
products, you can easily upgrade to a new Data Translation board. Little or
no reprogramming is needed.

Software Options
The following software is available for free and provided on the Data
Acquisition Omni CD:• Device Driver –The device driver allows you to use the PCI DAQ board
