Ruby-MM-416
Ruby-MM-416 4 Channel 16-bit Analog Output+24 DIO PC/104 Module The new 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.
Ruby-MM-412/812/1612
Ruby-MM-412/812/1612 4, 8, or 16-Channel 12-bit Analog Output PC/104 Module The Ruby-MM series provides 4, 8 or 16 channels of 12-bit resolution analog voltage outputs plus 24 digital I/O lines on a single PC/104 module. An on-board precision voltage reference circuit offers analog output ranges of 0-2.5V, 0-5V, and 0-10V in unipolar mode or ±2.5V, ±5V, and ±10V in bipolar mode. All analog outputs can source or sink up to 5mA simultaneously. The analog outputs are based on the DAC8412 quad 12-bit D/A converter chip. This chip resets all outputs to mid-scale on power-up, meaning 0V for bipolar ranges and 1/2 the full-scale voltage for unipolar ranges. To obtain power-on reset to 0V for unipolar ranges, a special-order version is available using the DAC8413 which powers up to zero scale instead. On the 16-channel model, each group of 8 channels can be set for a different output range. On the 4- and 8-channel models, all outputs have the same output range. All outputs are updated simultaneously, either with a software command or in response to an external trigger. The board includes 24 digital I/O lines using an 82C55 chip. All I/O lines have 10K Ohm pull-up resistors for guaranteed logic levels on power-up. Ruby-MM-1612 is designed and tested for extended temperature operation (-40 to +85oC). It requires only +5VDC from the system power supply via the PC/104 bus. Analog ±15V supplies are derived from miniature DC/DC converters on the board. All I/O is contained on a single 50-pin connector compatible with standard .1” connector ribbon cables, such as Diamond Systems’ C-50-18.
