4-channel input card DNx-AI-254 series

for linear displacement sensorsprogrammable

4-Channel, 16-bit, LVDT/RVDT Interface Features 4 LVDT/RVDT input channels or simulated outputs 16-bit resolution 4, 5 and 6-wire device support 2 to 6.7 Vrms programmable excitation per channel 100 Hz to 5 kHz excitation frequency range Up to 50 mA excitation current Fully Isolated (Chan to Chan and Chan to Chassis) The DNx-AI-254 is a four channel LVDT/RVDT input and output simulation boards for UEI's powerful data acquisition and control chassis. The boards are ideally suited for a wide variety of rotational and linear motion measurements in many industries. The boards also offer a unique LVDT/RVDT simulated output capability designed to provide stimulus in avionics test and simulator applications. Each of the four channels on the board may be configured as either an input channel with excitation or as an output/simulator. The 4 input channels are compatible with 4-, 5- and 6-wire LVDT/RVDT configurations. The board's high precision circuitry combined with each channel's independent 16-bit A/D converters allow an overall measurement accuracy of better than 0.1%. The inputs may be read at rates up to 500 readings per second, depending upon the reference frequency. Each channel provides an independent excitation output user programmable from 2 to 6.7 Vrms at frequencies from 50 to 5,000 Hz. The excitation output is capable of driving currents up to 50 mA, suitable for driving primary impedances as low as 90 ohms at excitations up to 6 Vrms.
