General Description:
The DNA/DNR-AO-308 are high-precision, true 16-bit, 8-channel voltage
analog output boards compatible with UEI’s “Cube” and RACKtangle chassis
respectively. The boards offer per-channel digital offset and gain calibration,
buffered output, excellent linearity, and low output noise. DNA/DNR-AO308 layer is capable of outputting ±10V with maximum current of ±5mA per
channel. This board is recommended for output applications that draw less,
then ±5mA. For applications that require higher output current, use DNA/
DNR-AO-308-350 layer.
The outputs of the DNA/DNR-AO-308 are fully isolated from the I/O chassis as
well as from other I/O boards within the I/O chassis.
DNA-AO-308 supports UEIDaq Framework Data Acquisition Software
Library for Windows. Linux and QNX drivers available. Visit our website for
more details.
