DT9801-EC-I

Key Features• Includes free QuickDAQ software to get up andAnalog Inputs
All DT9800-EC-I Series modules feature 16 inputs that canbe configured as 16 SE or 8 DIFF inputs. In addition, anAmp Low connection allows SE inputs to be referenced
to a common point other than ground to provide 16pseudo-DIFF inputs. Software-selectable gain settings of1, 2, 4 or 8 provide input ranges of ±1.25 V, ±2.5 V, ±5 V,and ±10 V. On the DT9801-EC-I and DT9802-EC-I, unipolar
input ranges of 0-1.25 V, 2.5 V, 5 V, and 10 V are alsoavailable. For added flexibility, a 32-location channel-gain
list allows you to sample nonsequential channels andchannels with different gains. The A/D resolution andmaximum sample rate vary depending on the board type.

Digital I/O

By offering board types with different features, theDT9800-EC-I Series provides the right cost-effectivesolution for your data acquisition needs. The analog
input subsystem can be completely software calibratedfor hands-off operation.

All DT9800-EC-I Series modules feature 16 digital I/O lines.
These lines are divided into the following 8-bit ports:• Port A, input• Port B, output±500 V Isolation Protects Your Data

You can also read the status of Port A at rates as high as
the maximum speed of the A/D by including the digital
input lines of Port A as a channel in the analog channel
gain list. This dynamic digital input feature allows you totime stamp the digital inputs in relation to the analog
inputs. In this mode, all 8 digital input lines of Port A are
read as one word. The digital outputs have sufficientcurrent capability to drive external solid-state relay
modules (sink 12 mA and source 1 mA).

Because USB modules reside outside the computer, they
are susceptible to ground spikes. These spikes can cause
system crashes and may even cause permanent damage
to your computer. The DT9800-EC-I Series features ±500 V
galvanic isolation that protects your computer fromground spikes and ensures a reliable stream of data.

Analog Input Acquisition Modes
DT9800-EC-I Series modules can acquire a single value
from any channel or a number of samples from multiple
channels. To acquire data from multiple channels,
DT9800-EC-I Series modules provide two scan modes:
continuously paced and triggered scan mode. Using
continuously paced mode, the board scans the channel
gain list continuously and acquires data until you stop
the operation or until a specific number of samples isacquired. Using triggered scan mode, the board scans
the channel-gain list at high speeds with a programmed
interval between scans, emulating a simultaneous
sample-and-hold operation. You can pace either scanmode using an internal or external clock.

User Counter Timers
Two dedicated counter/timers are available for counting
events, creating a pulse or frequency output, or
measuring a frequency output. The counters can besoftware cascaded or can be connected together on thescrew terminal accessory. You can also set the duty cycle,
frequency, and output polarity of the output pulse fromthe user counter/timers.

User Connections
The DT9800-EC-I Series modules each have three mass
termination connectors: two 26-pin locking 3-M type,one for analog input and one for analog outputs, clocks
and triggers, and counter timers, and a 50-pin connector
for digital input/output connections. A single USB cable,shipped with each DT9800-EC-I Series module, provides
both power and connections from your PC. No external
power or battery is required.

Analog Trigger Modes
Internal Triggers• Software trigger• Triggered scan counter
External Trigger: External TTL trigger input

The DT9804-EC-I-BNC versions offer the convenience ofBNC connectors for all analog inputs and outputs. In
addition to the BNC connectors, these versions include
a 37-pin SUB-D male connector for analog inputs andoutputs, as well as a 37-pin SUB-D female connector for
all digital signals.

The external A/D sample clock and the digital trigger
input signals are accessible through the user connector.

Analog Outputs
The DT9802-EC-I modules feature two analog output
channels. These outputs have a 12-bit resolution andoutput range of ±5 V, 0-5 V, ±10 V, 0-10 V. The
DT9804-EC-I and DT9804-EC-I-BNC modules feature two
16-bit analog outputs with a range of ±10 V.
