DescriptionThe OMB-DBK5 current-output card provides OMB-DAQBOARD-2000 Series data acquisition systems with the ability to control four isolated 4 to 20 mA current loops. The OMB-DBK5 acts as a current loop transmitter by modulating current from an external source. The OMB-DBK5 can be programmed with a static value whenever the data acquisition system is not transferring A/D data. As many as sixty-four OMB-DBK5’s can be used in one system, to obtain up to 256 outputs.
