Hi TS9,
All of the industrial (30V and 60V) digital IO boards are only supported in DAQmx. We offer the 5 volt PCI-6509 which can drive up to 24 mA. But if you need it to control a higher voltage you would need to purchase one of the relay accessories with it.
You can get the compatability VI's here:

If you are really in a crunch, we do have the Traditional DAQ compatability VI's. These compatability VIs allow you to use your MX only device in the traditional DAQ programming environment. They should allow you to use the 6514 with LV 6.1. However, these compatability VI's are only meant to be a temporary solution to ease t
he difficulty of people moving to DAQmx. The best long term solution would be to upgrade to LV 7.1 and use DAQmx. In the future, devices will be offered only in DAQmx as Traditional DAQ is phased out.
