• I can parallel two solid state relay ports for a maximum current of 1 AMP USB-6525?

  Hello

  I plan use USB-6525 to change a PSU 7VDC/1 AMP DC.

  USB-6525 having only 500 my maximum current for each channel, I can two parallel ports of relay to solid state for a maximum current of 1 AMP?

  Is it safe to use in this way?

  If not, is there any other USB device can provide 1 channel AMP relay?

  Thank you

• Turn it on and an Opto SWITCH with USB-6525

  The attached photo, a composition of a circuit consists of: Mitsubishi PLC FX series, USB-6525 and OPTO Switch (PNP OTBVP6). In the code, I put under tension of the OPTO then cutting the voltage; power on/off, using the USB-6525.

  My problem comes when that at some time in my code, the OPTOMETRISTS remain without electricity (immediately after programmatically, I just

  They shall ensure with outputs USB-6525 high level). I already checked the code, in my opinion its seems fine. I have in mind the 6525 isn't a fast DI / DO peripheral, that's why I use delays above 200ms.

  The last hope is to change the USB6525 for a brand new, it's what I'll do. But if anyone see a problem with the code or has another explanation why the OPTO not to receive or be (somehow) not powered, I'll really appreciate your help.

  I really need help.

  Thanks to all in advance.

  I found what was going on. Connectios, common, everything was fine. In the code, between the States (I use a state machine structure) missed me a delay of 200ms. This because I change the outputs to reading entries, so between them missed me a delay, that's all. in any case, thanks for your help!

• USB-6525 NiDaqmx how to detect where the device interrupts the communication

  This could be considered a more generic question for NiDaqmx, but I write a custom control for internal use with the USB-6525 and possibly other devices of i/o using c#.  I use DigitalChangeDetectionEvent to warn me when an entry has changed and everything seems to work very well.  In an effort to be complete, I decided to unplug the USB cable and see the result and found that no error has been detected until I tried a writing output.  This is not acceptable because under normal conditions abstraction entry begins a process that will change output - given that admission never happens, the system is basically hung.

  I tried many things and have spent more time on what I want to admit so I would like to hear suggestions on how to address this problem.  Here are my attempts that I am not satisfied:

  (1) periodically switch (pulse) output that allows to detect the problem, but I may not be an available exit, so this isn't a good situation.

  (2) periodically trying to read the input byte with the same entry workflow, this does not work because I believe that the other player is still active with the DigitalChangeDetectionEvent.

  (3) attempted to take the message of Windows to change hardware, but seems too complex.

  (4) I read on the guard dog, but not sure that it is available on the box USB-6525.  So before I start with this I'd hear rather suggestions of others with more experience.

  Any suggestions please?

  Hi IntegroEd,

  Those are all very innovative way to potentially address the problem, and I'm sorry you haven't seen success with them.  Fortunately, the typical way to capture a break between a device of data acquisition and monitoring system is indeed a timer, and the 6525 has the innate ability to use the feature, as seen on page 5 of the user manual.  I suggest you go that route, if another user does not post a peripheral solution specific to your case.  This is a documentation on the implementation of the monitoring-

• State of relay by default USB-6525

  Hello

  When the NI USB-6525 enclosure is powered on the default state to solid state relay is closed.  I'm trying to use it to control a 4 position RF switch.  Obviously we do not want to be on as this disrupts the 4 switch inputs.

  Is it possible to change the default state of the relay, so that when the device turns on the relay are all open rather than closed?

  Hi SeanJ,

  Sorry for the delay on this point - I just noticed this post by searching for clients who may have encountered this problem.

  From DAQmx 8.9, programmable start-up States have been added to the USB-6525.  However, flash on these cards was not initialized correctly to 'open' State, so the check for PPS caused tips have added a default PPS to 'closed '.  The solution is to simply set the States start to their desired state.  This can be done through MAX as follows:

  

  

  All the councils that are currently on the market have their flash correctly initialized to the open State.

  To reduce the risk of this question anyone adversely affecting during updates, we also add a check for the firmware in DAQmx 9.2.2 and later charger to initialize the flash if you are upgrading a version of the driver without PPS.  If the upgrade to a version of the driver with PPS, the startup States will not be affected.

  More information can be found here:

• USB-6525

  Hello

  At first, I want to control a USB-6525 in labview. I want to creat 3 switch control relay as if switch1 is out of relay 1 is open, switch2 is narrow so relay is close

  Can I control switch using the DAQ (Labview8.5) Wizard, I choose relay wich I want to open/close, but I don't know how to connect with a switch for failing to enter the DAQ assistant.

  Secondly, I would like to control them by timers but I first want to understand how it works with the simple switch

  Thank you

  Kind regards

  PS: I'm french so sorry for typos

  Please answer me

  I'll try that

• measure the State of the output to USB-6525

  Hi, is it possible to check the status of microsatellites in a USB-6525 using a multimeter.  I hooked up a meter to measure the resistance through the P0.0A and P0.0B output connections.  I wanted to use the automatic test routines to check the SSRs were closing.  As expected, there was an open circuit when LIFE expectancy was 0, but the circuit seemed not close when I changed the TTL of 1.  Do I need to connect to a power source and load to be able to see the closing SSRs?  Is not which is what a multimeter?

  Thank you, Nick

  Nick,

  Multimeter will not provide the source of tension and support you need.  Check out this link.  http://digital.NI.com/public.nsf/allkb/B0FF01B2AFFA52FC862573A2005A9570

• USB 6525 6501 digital for output to the step motor

  Hello

  I try to use USB 6501 or USB-6525 out of step motor signals which command the stepper motor. My questions are

  (1) do I 6525 USB, I'm not sure the function of it (perhaps as a relay).

  (2) now I connected input 5V for USB-6501 "+ 5V" pin and GND to pin "GND". On the other side (output side), I connected ' enable '(from motor drive) to P0.0. 'direction' to P0.1 and GND to GND.  Can I use the express signal to test, the error says "lack of entry."

  (3) I guess the next step is programming labview. Does anyone know of similar examples?

  Any help would be appreciated!

  Melody,

  If the engine must input external logic level I advise to use the USB-6501, which is just a digital I/o card. The USB-6525 housing does not have the digital outputs to control your motor drive. If I understand correctly you just try to turn the motor on and off with a digital signal. It seems that you also provide your drive motor + 5 v and GND. The USB-6501 has channels for + 5V and GND. I've attached an example of navigation that controls the outputs digital using DAQmx and LabVIEW. This specific programme allows to control 8 digital output lines, but it looks like you don't have one. If the engine waiting for you just a strong to put logic in operation and a logic low to shut down this program example will be able to turn on or turn off your engine. Just connect one of the USB-6501 digital output lines and then use the program to this line of control.

  I don't really know any reason, you need to use the USB-6525 it seems to me that the USB-6501 run action you need. I hope this helps.

• control solenoids with USB-6525

  Hi, I'm new to Labview and try to use a USB-6525 control six independent valves.  They'll be turning on and off at different frequencies to control a cell infusion system.  I drew a diagram that allows me to program schedules that the CRDD is closed and open.  The routine is inside a while loop to repeat until a given time has elapsed.  I can duplicate this six times to allow each valve must operate independently.  But I would like to trigger all tasks at the same time.  How do I synchronize loops so they all start at the same time?  Simply put all the loops inside a conditional loop, or it will run the tasks in the order?

  Thank you

• Recommendation of USB data acquisition

  Hello

  I'm looking for a digital acquisition of data NOR-USB 12v e/s of at least 8 channels. He would be grateful if someone recommends me.

• With the help of the meter from 6525 to measure the frequency: is there a more orderly way?

  I am currently using the high speed on a module USB 6525 meter to measure the frequency of an object in rotation via a sensor hall-effect.

  I was wondering if there was a simpler way / more effective this encoding than that?

  Everything that I currently perform the current meter reading, wait a second, take another reading, and subtract one from the other. The result is the frequency in hertz.

  Is there a way to get the 6525 to return the number / change County after 1 second?

  Thank you

  

  On the 6525, you have a country of the event and you can't make a measure of frequency.

• Names of relay USB-6526

  I am trying to manipulate the SSRs on a USB-6525 using the driver DAQmx ANSI C. I use DAQmxSwitchCloseRelays and DAQmxSwitchOpenRelays, but I get the error "Relay not in the list. I feel like I'm missing or adding a "/" somewhere, but I could use help to identify the right float [] to switch to the routine.

  Hi nightrider,.

  Welcome to the forums EITHER!  The USB-6525 is considered as a digital I/o as opposed to a switch device and would use one of the DAQmxWriteDigital... functions.  A good starting point would be the example WriteDigChan.  The example should be in the following location:

  Documents and Settings\All Users\Documents\National Instruments\NI - DAQ\Examples\DAQmx ANSI C\Digital\Generate Values\Write dig Chan

  The switching functions are used by our peripheral switchPXI and SCXI; Sorry if that was confusing.  If you are having problems please let me know.  Thank you and have a great day!
