Ruby-MM-416
4 Channel 16-bit Analog Output+24 DIO PC/104 Module
 |
Description |
The Ruby-MM-416 PC/104 module provides 4 channels of 16-bit resolution analog voltage output. The output range for each channel can be independently selected for 0-10V, ±5V, or ±10V with jumpers. All outputs are updated simultaneously, either with a software command or in response to an external signal. The board includes 24 lines of digital I/O using an 82C55 chip. The I/O connector pinout is compatible with the Ruby-MM-4 12-bit analog output board shown in our catalog on pages 20-21. Other features include +5V-only operation, individual DC/DC converters with filtered outputs for each DAC to supply ±15V for operation, and a six-layer circuit board to bury and shield the analog signals.

Analog Output Ranges |
For any output range, the resolution is equal to the maximum possible range of output voltages divided by the maximum number of possible steps. A 16-bit D/A converter has very high resolution, because the maximum number of steps is 216 = 65536 (the actual output codes range from 0 to 65535, which is the full range of possible 16-bit binary numbers). Thus the resolution is equal to 1/65536 times the full-scale range. This is the smallest possible change in the output. It corresponds to a change of 1 in the output code, and therefore it is often referred to as the value of 1 LSB, or 1 least significant bit.

I/O Header Pinout |
A 50-pin header is used for all I/O. This header is compatible with our Ruby-MM 12-bit D/A board, allowing an easy upgrade path for current 12-bit users.
