I noticed a few other topics related to turnstiles.
We are using a ProXR Lite relay board to control 4 turnstiles via enterprise software called Fusion. We have a random dropout of USB devices (card readers at the turnstiles) to our control PC. Causing gates to not open. Works fine for a while after a reset
Turnstiles are wired directly with dry contacts to the relay board.
Relay boards are powered by external power and USB is plugged into a USB hub.
USB Hub also has usb-cat5 extenders plugged in (for the card readers).
Would an Induction suppression capacitor be needed? If so, where would they be wired into?
Yes, this sounds like a typical induction issue. This article shows a wiring diagram of how to install an induction suppression capacitor between the relay and the load.
We sell these induction suppression capacitors here:
If you have any other questions please let us know.
Thank you for getting back to me. We had an electrician check out our wiring from the boards and turnstiles. The electrician is saying that the motors being used are 3-wire and not 2-wire.
Any thoughts on how to go about installing these capacitors? We have read through the link above but it is unfortunately wired differently than our setup.
