The DAC 212 is a powerfull peripheral, low price, high resolution, digital to analog converter card.

It is a 4 Type format module, capable to generate two indipendent analog output signals with 12 bits resolution and selectable range.

The electric connection of the card is performed through three confortable connectors: one for the control cards with Abaco® I/O BUS, one for an eventual external reference voltage and the last one for the output analog signals; the mechanical mounting is simplified by a proper plastic support for DIN 46277-1 and DIN 46277-3 omega rails.

The on board analog circuit can generate signals in a large range of possibility; the output range selection is performed through a set of jumpers that can define three different scale: ±10 V, 0÷10 V and amplifier of an external reference signal.

An optocoupled DC/DC converter generates all the required voltages starting from a single power supply of the card.

A wide range of demo programs on how to use this card, allow an immediate use of the same.

These programs are available for the whole CPUs of Abaco® family.

They are duly documented and supplied under "source" form in the many different languages in which Abaco® cards can be programmed.

• - Interface for Abaco® I/O BUS on 26 pins standard low profile connector.
• - Dimension: 100x50x40 mm, (110x60x70 mm with container) in 4 type format.
• - Plastic support for DIN 46277-1 and DIN 46277-3 rails.
• - One D/A Converter section, 2 channels,12 bits, based on DAC 2815.
• - Output range selectable by hardware through jumpers.
• - Available output ranges: ±10V, +10V or amplifier of an external Vref signal.
• - De coupling filters on both analog outputs.
• - DC/DC converter for D/A converter section.
• - One 4 pins quick release screw terminal connectors, for two analog outputs.
• - One low profile 2 pins connector for the eventual external Vref.
• - Only 4 consecutives Bytes used for card I/O addressing.
• - Card I/O allocation address defined through proper dip switch.
• - Single power supply voltage: +5 Vdc; 220 mA.
