USB-DIO24SeriesandUSB-1024Series

USB-DIO24 and USB-1024 Series provide

24 DIO channels configured as either two

banks of eight ports and two banks of

four ports, or three banks of eight ports.

Each port is independently configurable

for input or output.

The USB-DIO24/37 and USB-1024LS are

designed with an 82C55 interface chip.

USB-DIO24 Series boards (left) provide 24 DIO. The USB-1024 Series (middle) provide the

same functionality as the USB-DIO24 Series and are shipped in a case. USB-DIO96H Series

(right) provide 96 DIO, high-drive current output and are shipped in a metal enclosure.

The USB-DIO24H/37 and USB-1024HLS

are designed to emulate 82C55 mode 0.

Outputsarehigh-driveTTLthatcansource

15 mA and sink 64 mA.

Digital I/O lines are accessed through

a 37-pin D-type connector on the

USB-DIO24 Series, and through screw

terminals on the USB-1024 Series. USB-

DIO24 Series are board-only, while the

USB-1024 Series are shipped in a case.

Overview

The USB-DIO24, -1024, and -DIO96H Series are digital I/O data acquisition devices.

The USB-1024 Series adds 24 lines of logic-level digital I/O to any USB port. The

USB-1024HLS high output current can drive many logic level devices directly,

eliminating the need for costly buffer circuitry.

The USB-DIO24 Series has all the functionality of the USB-1024 Series, but is

enclosed in a case and designed with a D connector that matches the PCI-DIO24,

making it easy to replace PCI boards in your applications.

The USB-DIO96H Series provides 96 lines of high-current, logic-level, bidirectional

digital I/O. The units offer 4 independent 24-bit DIO groups, each divided into

two 8-bit ports and two 4-bit ports. The outputs can drive a wide assortment of

external devices directly, without additional buffering. USB-DIO96H Series are

housed in a heavy-duty chassis with integrated mounting slots.

USB-DIO96H Series

The USB-DIO96H Series provides 96 DIO

channels that are configured as eight

banks of eight ports and eight banks of

four ports. Each port is independently

configurable for input or output. USB-

DIO96H Series devices are designed to

emulate 82C55 mode 0. Digital outputs

are high-drive TTL that can source 24

mA/sink 64 mA.

Digital I/O lines are accessed through the

screw terminals on the USB-DIO96H, and

through the header connectors on the

USB-DIO96H/50. USB-DIO96H Series

boards are shipped in a rugged metal

enclosure that you can mount on a DIN

rail or bench.
