DT9824

The DT9824 USB data acquisition (DAQ) module offers the highest stability and accuracy for measuring analog signals. Every signal input, both analog and digital is fully isolated from each other. This technology, ISO-Channel™, guarantees that all signals are protected from any environmental or system noise.

The high stability design of the DT9824, with a temperature coefficient of ±0.05µV/° C, and a CMRR of greater than 150dB, delivers data acquisition results that are twenty times better than the normal solution from another system.

The DT9824 is ideally suited for chromatography, seismic, weigh scale, and medical applications where accuracy and stability are imperative. The rugged, compact module is fully powered by USB and can be used as a portable device or mounted in a rack.

Key Features:

VOLTAGE INPUTS

• 4, simultaneous, 24-bit analog input channels
• ISO-Channel technology provides ±500 V galvanic isolation channel-to-channel for all analog input signals and to the host computer ...guarantees noise immunity
• Input gains of 1, 8, 16, and 32 with input ranges of ±10 V to support the following effective ranges: ±10 V, ±1.25 V, ±0.625 V, ±0.3125 V
  ...allows maximum flexibility for any signal input

ADVANCED SAMPLING MODES

• Sampling frequency up to 4800Hz
• Continuously paced analog input operations
• Software-programmable trigger type (software or external digital trigger) to start analog input operations
• Channel Gain list allows measurement of any combination of channels/gains

ISOLATED DIGITAL I/O

• 8 opto-isolated digital input lines
• 8 opto-isolated digital output lines; the outputs are solid-state relays that operate from ±30 V at currents up to 400 mA (peak) AC or DC data stream for correlating analog and digital measurements
• Digital I/O galvanically isolated to 250 V
• Read the digital input port through the analog input

The DT9824 provides ultra-high accuracy and stability while also providing ISO-Channel protection from any noise conditions. Each analog input is galvanically isolated from any other input and has its own return path. This means that other “grounds” or return paths from other signals or from the computer have no possibility to interfere with an ISO-Channel input or return. The shielded steel enclosure, 1U by ½ rack, further enhances noise immunity.
