IO Connectors
The QueBec Pro has two I/O (Inputs/Outputs), which can be configured as
output or input. Each I/O is available for connection to a PIR (movement)
sensor, keyboard lock, relays or for other compatible uses. The ports are
not potential free; you may need external relays to prevent ground loops
depending on your application. Or use the relays on the QueBec Pro.
When used as outputs, the I/O ports are active low. When activated, the
I/O ports are tied to GND through a FET transistor (also called open drain/
collector function). Each I/O can draw up to 24VDC/500mA.
When used as inputs, the applied voltage must be below 1 VDC to be
accepted as LOW, and above 4 VDC (but below 24 VDC) to be accepted
as HIGH. The inputs are default HIGH and must be connected to ground in
order to change state.Relays
Relays
Relays are used when a external control is needed where there must be
potential free connection between the control and the QueBec Pro.
The relays are normally open types. This means that the terminals are not
connected when the relay is off.
