Problem: What National Instruments products can be used for current output?
Solution: The following devices support current output:
- Multifunction DAQ
- PCI-6704 - 16-bit static-update analog output board, 16 current outputs that you can use at the same time independently and set from 0 to 20 mA.
- PCI/PXI-6238/6239 - Two 16-bit analog current outputs, 0 to 20mA.
- DAQCard-AO-2DC - 2-channel voltage and current output card (Type II) for PCMCIA
- NI 9265 - Supported using NI 9172 Compact DAQ chassis (see below)
Current Output is not directly supported by most of National Instruments' Multifunction DAQ devices.
However, if the load is known then an appropriate voltage can be used to source up to 20 mA of current from an analog output channel.
- SCXI
- SCXI-1581 - Provides 32 channels of 100 µA current excitation.
- SCXI-1124 - Provides 6 programable channels of 0-20mA current excitation.
- SCC
- SCC-CO20 - Single-channel isolated current output module that can provide up to 20 mA.
- FieldPoint
- c[FP]-AIO-600 - 8-channel, single-ended, combination analog input/analog output module, which has an internal update rate of 1.7 kHz
- c[FP]-AO-200 - 8-channel analog output module for 4 to 20 mA and 0 to 20 mA current loops.
- cRIO and CompactDAQ
- NI 9265 - 4-channel, 0 to 20 mA, 100 kS/s simultaneously updating analog output module for any CompactRIO or CompactDAQ chassis.
