Hello,
I have a K8000 connected to a K6714-16 relais card.
Sometimes, an open relais close by itself a fraction of second and return to its open position.
My VB program ask the K8000 to open the relais on a defined time and ask to this relais to stay open every 100 milisecond.
So, an order is send every 100 milisec to stay open.
the K6714-16 s assembly manual speek about an optional noise reduction with condensators and resistances.
Could this option be the solution to my problem?
Thank U.
And another question, what do velleman means by “noise reduction” for k6714?
Whats the purpose of the option “noise reduction”?
No explications delivered yet about it.
There is no need to refresh the status of the I/O.
Most likely, that is the reason why something goes wrong.
As for the ‘noise reduction’, this is only necessary with inductive loads, such as motors, solenoids etc…
ok, my k6714-16 card manage some inductive load devices. But It don’t have the noise reduction option configuration.
You tell me it’s “necessary” but what are the conscequences if I don’t reduce the noise for an inductive load?
Do I dammage those devices in long term or not? because I HAVE dammages on my devices already. I need to know where my problems come from …before buying all again…(of course).
Tell me more about the exact purpose of your “optionnal noise reduction” for K6714
Thank U.
To prevent damage to relay contacts, it is recommended to use a snubber network when switching inductive loads.
Please Google for more info on this matter.
Ok thank you, now I know its my on-off switch who had damaged my devices. Not this relais noise reduction.
Most likely a problem with my K8000.
Last question, can U tell me if I can use the VM140 usb card with windows7 32bit and 64bit?
Thank U
