Diamond Systems 16-Channel 12-Bit Analog Output PC/104 Module, RUBY-MM-1612 user manual Description

1. DESCRIPTION

Ruby-MM-1612 is a PC/104-format data acquisition board that provides analog outputs and digital I/O for process control and other applications. Below is a summary of key features:

Analog Outputs

Ruby-MM-1612 has 16 analog voltage outputs with 12-bit resolution (1 part in 4096).

⇒Note: Analog output, D/A, and DAC are all used interchangeably in this manual.

Multiple Full-Scale Output Ranges

Six different preset ranges are available, including both bipolar and unipolar ranges.

Adjustable Full-Scale Output Range

One of the preset ranges (2.5V full-scale) can be adjusted by the user to any voltage between approximately 1V and 2.5V.

Simultaneous Update

All 16 analog outputs are updated simultaneously. This prevents time skew errors which can result from updating outputs sequentially on a system which requires two or more control signals to change simultaneously.

External Trigger

An external trigger signal can be connected to the board. This trigger can be used to update the analog outputs. The trigger is enabled in software.

Digital I/O

An 82C55 chip is included to provide 24 lines of digital I/O. Each line has a 10KΩ pull-up resistor. Each line is CMOS / TTL compatible and can supply up to ±2.5mA of current.

+5V Operation

Ruby-MM-1612 requires only +5VDC from the system power supply for operation. It generates its own ±15V supplies for the analog circuitry on board using four miniature DC/DC converters.
