VMIVME-4514A 16-Channel Scanning Analog I/O Board
The VMIVME-4514A is a 16-Channel, 12-bit Analog Input/Output (AIO)
Board. It provides both the stimulus and the response functions encountered in
VMEbus based closed-loop analog systems. The analog signals are available at the P2
backplane connector. It is self-contained, with a resident 12-bit Analog-to-Digital
Converter (ADC) and a Digital-to-Analog Converter (DAC). The board also supports
a Built-in-Test feature that checks all of the active components on the board. The
VMIVME-4514A provides a single board solution to the analog input/output
requirements of such VMEbus applications as process control, simulators, trainers,
and supervisory control.
The VMIVME-4514A provides the user with 16 analog outputs with 12 bits of
resolution. The outputs are designed with individual Sample-and-Hold (S&H)
amplifiers, one per channel. The outputs can be programmed (via on-board jumpers)
to operate in a variety of voltage ranges. These ranges are 0 to +5 V, 0 to +10 V
(unipolar), ±2.5, ±5.0, or ±10 V (bipolar). Each output can source or sink up to 10 mA
at ±10 V. The outputs can be disconnected from the I/O connector for off-line testing.
The board also accepts 16 analog inputs. These inputs may be differential or
pseudo-differential (single-ended). A 36 Hz single pole input filter may be ordered for
the inputs. The input ADC can be programmed (via on-board jumpers) to operate in a
variety of voltage ranges. These ranges are 0 to +5 V, 0 to +10 V (unipolar), ±2.5, ±5.0,
or ±10 V (bipolar). The inputs have 12 bits of resolution. The inputs can be scanned by
on-board multiplexers, and the data stored in a dual port memory.
