Analog input boards support multiple monitoring applications
United Electronic Industries (UEI) offers four new analog input boards featuring 8 analog input channels, 24-bit A/D resolution, and 120 kilosample/second maximum sampling rates. The DNx-AI-218 offers a ±10 VDC input range suitable for most general-purpose data acquisition measurements while the DNx-AI-228-300’s ±300 VDC input range targets 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 software programmable, and the boards go into high impedance mode when power is removed, for use in high-reliability, redundant monitoring applications. Additionally, UEI provides factory written software drivers for all popular operating systems including Windows, QNX, VxWorks, RTX, InTime, and more.
