Description

The 4-channel OMB-DBK2 voltage-output card provides OMEGA’s OMB-DAQBOARD-2000 Series data acquisition systems with the ability to generate precise bipolar analog voltage outputs. The OMB-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 program-mable voltage sources or the control of devices such as programmable power supplies and process controllers. Up to 64 OMB-DBK2 cards can be attached to one OMB-DAQBOARD-2000 Series card, for a total of 256 outputs.

Card Architecture
The OMB-DBK2 features a quad 14-bit D/A converter that permits| it to generate up to a ±5 V or ±10 V voltage. Voltage ranges are jumper selectable per channel. The card is also equipped with an on-board bipolar reference to ensure accurate and stable output voltages.

Applications
The OMB-DBK2’s precise voltage output makes it especially useful for applications that require programmable voltage sources or test-signal generation.

It is also ideal for applications that devices such as programmable power supplies, proportional actuators, analog indicators, and process controllers.
