8 Channel, 24 Bit A/D Boards Are Fully Isolated

Boards provide 8 analog input channels, 24-bit A/D resolution and 120 kilosample/second maximum sampling rates.

Four new boards from UEI offer 8 analog input channels, 24-bit A/D resolution and 120 kilosample/second maximum sampling rates. Two DNR versions are for use with the company’s RACKtangle chassis, while two DNA versions are designed for installation into the PowerDNA Cube chassis. The DNx-AI-218 offers a ±10 VDC input range suitable for general purpose DAQ measurements, while the DNx-AI-228-300’s ±300 VDC input range suits it for high voltage applications such as battery testing, power plant monitoring and aircraft power monitoring. The boards all offer complete, 350 Vrms channel-to-channel and channel-to-chassis isolation, and provide simultaneous sampling with each channel being based on its own oversampled SAR converter. Input gains of 1, 2, 4, 8, 16, 32 and 64 are fully software programmable, and the boards go into high impedance mode when power is removed, suiting use in high reliability, redundant monitoring applications. The DNR-AI-218 and the DNR-AI-228-300 for RACKtangle chassis, and the DNA-AI-218 and the DNA-AI-228-300 for Cube chassis are all priced at $1750 with delivery 4-6 weeks.
