USB-2416-4AO DI/O Support for Python
smann posted a question in Data Acquisition (DAQ) & Data Logging
Hi below is my simplified code reading the live value of AI3 a position sensor. The issue I am seeing is in the code I am unable to use ULRange.UNI10VOLTS as it is not supported, I tried ULRange.BIP10VOLTS in the code. The issue with Bipolar is the -10 to 10 range doesnt match the position sensors 0-10V range so it is showing minus values instead of the correct positive 0-10 values. Is there a way to check why my code is not showing the same value as instacal. Instacal shows the signal the best, very steady signa; while Daqami has somewhat steady signal and my code shows not steady signal and is negative. It is weird how instacal and daqami show different steadiness. Any idea why my position sensor code is only letting me use BIP10VOLTS and not UNI10VOLTS. I think if i am able to use the correct 0-10V it will fix the negative value seen and the variation. a_in_scan_file_2416_Rev13_lvit_testing.py -

I changed the fuse on the solenoid valve relay side and it is now actuating. I guess the fuse blew first when both valves turned on by the relays. Thanks,

Hi, So I have gotten the digital outputs 0 and 1 working with my solenoid valve. I accidently turned both on at the same time so I think blew the fuse in the 5V connection in the DAQ. Is there anyway to verify this? The relay still shows being actuated but the valve itself is not actuating. Any suggestions would be helpful. Thanks,

Hi I have a flow meter I am using with a counter input on the USB-2416-4AO. Below is the manual for the counter. How can I scale this to be from a counter value into a flow reading in python. The DAQami is reading, but is reading zero as I have no flow for that. Is this something that is expected? Flo-tech-F5140-F5141-manual.pdf

Wire Connections on USB-2416

Hi @DAQman, We are using 2 SSR's but not at the same time, the power supply is to power the solenoid valve. Thanks, -
USB-2416-4AO DI/O Support For solid state relay

I am using my own 24V power supply to power the solenoid valves How can I wire it to the analog input, looking at other projects that seems more straight forward then digital output -
USB-2416-4AO DI/O Support For solid state relay
smann replied to smann's question in Data Acquisition (DAQ) & Data Logging
This is the relay: https://www.digikey.ca/en/products/detail/sensata-crydom/DR10D10/14834324?s=N4IgTCBcDaIIwHYwFoAiAlOAGV3kDlUQBdAXyA I understand connecting the +5 Volts and the coil minus to digital output.However I do not understand where the 5Volt ground to GND is. Relay Input Side: Relay Input (+): Connect to the +5V power supply on the DAQ. Relay Input (-): Connect to the digital output of the DAQ. Relay Output Side: Relay Output Common (L1+)(C): Connect to the +24V power supply. Relay Output Normally Open (NO): Connect to the solenoid valve's positive terminal Solenoid Valve: Solenoid Valve Positive Terminal: Connect to the relay output (NO). Solenoid Valve Negative Terminal: Connect to the ground of the 24V power supply. Ground Connections: DAQ Ground (GND): Connect to the ground of the +24V power supply to complete the circuit. Am I understanding this correctly? -
For my 2 outputs controlling a 5V SSR relay, I am wondering if I instead need to use Digital Output instead of analog output as seen in the schematic below. Would the wiring be the same as below only difference being AO0 and AO1 being DIO0 and DIO1 and the grounds being attached to DGND?

Hi I am using the DAQ for measuring a pressure transmitter. Even at no pressure the DAQAMI software is reading unstable values when in theory it should be at constant 0 at atmospheric pressure. Any ideas on how I can get a constant reading from the DAQ, I confirmed it is wired correctly .

USB-2416-4AO Thermocouple Support for python
smann posted a question in Data Acquisition (DAQ) & Data Logging
I am using this file to detect thermocouple readings but the channel input 0 is not giving correct voltage/thermocouple. Below this is the output from channel. Any idea why both python has not given consistent voltage readings from the thermocouple. My instacal is working fine showing room temperature consistently. a_in_scan_file_2416.py scan_data.csv -

I want to confirm I can use python to create a live user interface for this DAQ? I followed a simple example on GITHUB but I get an error 41 This function can not be used with this board. -
USB-2416-4AO DI/O DAQ Thermocouple support

I ordered this specific daq because it has capabilities of supporting thermocouple measurement type but under device info it only shows voltage measurements, anyone know if there is a way to make it read thermocouples as advertised. -
USB-2416-4AO DI/O DAQ MATLABSupport
smann posted a question in Data Acquisition (DAQ) & Data Logging
I am using a K type thermocouple inserted into port AI0 on the DAQ and below is my code. I do not know why my graph is not a constant temperature reading, I have tried adjusting the dq.rate but nothing changes. I want to develop this code into a live user interface but cannot move forward until I get correct temperature readings. Thanks, -
Hello, I am using a USB-2416-4AO DI/O DAQ system and connected to channel AI0 is a K-type thermocouple. I have verified the thermocouple itself is working by using a Digital Multimeter and it shows room temperature. But when I connect to DAQAMI software it shows the following below. Any suggestions on what could be causing this issue? The graph shows a Celsius range of -100 to 160 where it should normally show a constant temperature.
