High-Stability Ethernet Data Acquisition Module with Four Simultaneous 24-Bit Analog Inputs
Data Translation announces the new DT8824 Ethernet data acquisition module designed for ultra high stability and accuracy. Its four galvanically isolated differential inputs each have their own separate 24-bit A/D converter. With 10 ppm accuracy, a temperature coefficient of 0.05 µV/°C and a common mode rejection > 150 dB, the module delivers data acquisition results that are 20 times better than comparable measurements solutions. A built-in web interface allows configuring the input parameters and monitoring the measurements locally or at remote sites by using a standard web browser.
The new Ethernet data acquisition module features Data Translation's proven ISO-Channel technology which guarantees high stability and accuracy. This technology includes custom DC/DC converters and digital opto-couplers that provide full channel-to-channel isolation of up to 1000V. The inputs can be sampled simultaneously at a sampling frequency of up to 4800 Hz per channel.
With input voltage ranges of ±10 V and individually programmable gains of 1, 8, 16 and 32, the DT8824 achieves a maximum resolution of 0.07 µV. Removable screw terminals on the module allow quick and easy signal connections. Four digital, fully isolated digital outputs are provided in addition to the analog channels. The digital outputs are designed as solid state relays that operate from ±30 V at currents up to 400 mA AC or DC. Using the Trigger Bus, up to 16 modules can be synchronized and up to 64 channels can be externally triggered.
The rugged steel enclosure makes the DT8824 ideally suited for use as a portable device or for mounting in a 19" rack. The instrument ships ready-to-measure, including a web-based application for viewing, graphing, logging and analyzing the measurement channels. In addition to limit checking, external processes can be monitored and controlled. The package also contains IVI-COM drivers, .NET class libraries and a Win32 software development kit.
