1. Why am I currently experiencing difficulties with the EasyDaq website ?
We apologise if you have experienced difficulties with our website in recent weeks. We are working hard to improve our overall service and this includes a complete update of our website and online shop. In the meantime if you have any queries please don't hesitate to email us at email@example.com
2. What is the fastest relay
switching or reading speeds?
As the communication speed between a PC and
the Relay modules is 9600 baud, this limits the rate of character
sending to approximately 5 milliseconds per character. It is
therefore advisable to place a delay of ideally 10 milliseconds, in
the control code, between character transmissions.
3. Why do the relays stop
working when switching heavy or inductive loads?
This is normally due to energy spikes
affecting the signals being sent to the relay module. Solutions to
this problem are:
suppression capacitors across the relay contacts. Suitable
types are available from the EasyDAQ website.
Reduce the length of the signal cable or fit a USB switching
hub close to the module.
4. Can the Relays be powered
independently of the USB supply?
Yes, there is a link option on the relay
boards that controls the means by which the relays are powered.
When fitted the relays are powered from the USB supply, when not
fitted the boards will require power from the alternative supply
