I need to measure from 0 to 2 Amperes range of DC current. Which NI current input module would be suitable? All I see is the range is from -20 mA to 20 mA.

It would depend on the application, number of channels, resolution, measurement rate and platform (PXI, cRIO, cDAQ etc.,)

Typically, NI DMM supports up to 3A (like PXIe4081). IMHO, higher currents are not supported by other PXI instruments, you could use an AI DAQ with an external current shunt to measure large currents.

PXI 4309 is a good multi-functional model intended for voltage and current measurements,
