How Does It Work?
Scan a barcode at a door, barrier gate (parking garage or parking lot entrance), or at a turnstile to gain access to an area. A kiosk, tablet, or PC connected to the same network as the PoE module sends a command to the 8-port relay module instructing it to open up the relay for a configurable number of seconds. This sends an electrical signal to the electronic control device such as an electric door latch, a barrier gate, or a turnstile allowing it to open for a set number of seconds.
Since this works off of a TCP/IP network, the device must be accessible from the PC or kiosk controlling the relay module in order for it to function.
