2.4.4 AXV11 Controller

The AXV11–S is an input/output circuit board for analog devices. The

AXV11–S is functionally equivalent to the AXV11–C.

Functional Information

Input channels 16 single-ended analog input channels or 8

differential analog input channels; SE/DI

jumper is ﬁeld-selectable.

Programmable gain 1, 2, 4, or 8

A/D output

Data resolution 12-bit output data resolution

Data notation Binary, offset binary, or two’s complement

Voltage Output voltage range selection of ±10 V (bipolar)

or 0 V to 10 V (unipolar)

A/D conversions Can be started by a program, an external trigger,

or a real-time clock

A/D results Can be received by a programmed I/O transfer or

by servicing an interrupt request

Common mode rejection ratio 80 dB at maximum range

D/A converters (DACs)

No. of DACs 2

Input (each DAC) 12-bit digital input

Output (each DAC) Unipolar or bipolar output

Ordering Information

UDIP–BA

Universal data interface panel (UDIP) mounting

box

UDIP–AY Universal data interface panel (UDIP) for AXV11–

UDIP–TA Tabletop enclosure

Performance

A/D converter performance

Linearity To within ±1/2 LSB

Stability (temperature coefﬁcient) ±30 ppm at maximum °C (32°F)

Stability (long term) ±0.05% change in 6 months

Conversion time 25 µs from end of front end settling to setting the

A/D DONE bit

You must order both a UDIP mounting box and an interface when installing a new option.
