The 4-channel DBK2 D/A voltage-­output card provides IOtech’s data acquisition systems with the ability to generate precise bipolar analog voltage outputs. The DBK2’s outputs can be programmed with a static value whenever the data acquisition ­system is not transferring A/D data. The card is particularly useful for applications that require programmable voltage sources or the control of devices such as programmable power supplies. Up to 64 DBK2 cards can be attached to one system for a total of 256 outputs.

The DBK2 features a quad 14-bit D/A converter that permits it to generate up to a ±5 V or ±0 V voltage. Voltage ranges are jumper selectable per channel. The DBK2’s precise ­voltage output makes it especially useful for applications that require programmable voltage sources or test-signal generation
