Good Morning,
Our project recently acquired the NI 9074 chassis along with the NI 9219. I have been tasked with researching how to use this with a current sensor. The project is in FPGA because the data needs to be saved onto SD cards with the NI 9802. After a few days of researching I finally have all the software up and running and the chassis is communicating with my laptop through Labview. Now my problem is collecting information from the sensors. Here is what I need to do and what hardware I have:
Honeywell - [CTS-10-250-VDC-001] - Solid Core Current Sensor w/0-10 VDC Output
NI 9074 Chassis with the NI 9219 module installed.
Hardware setup:
NI 9219 is connected into Module 1.
The sensor is connected into Channel 0.
Pin 4 is going to positive on the sensor.
Pin 5 is going to negative on the sensor.
We have set up two windmills and solar panels and want to get a voltage reading from each sensor we install. I am having problems setting up the first sensor. Any help or advice would be much appreciated.

Hello,
I am attaching an image from the User's Manual for the NI-9219 that describes the connections for the channels. Pin 5 an excitation/lo input pin depending on the configuration. Pin 6 is a lo input pin, if your signal from the sensor is just two leads that has a voltage range between 0-10 VDC then I would recommend using Pin 4 and Pin 6.
Regards,
Justin
