Function
These contacts must be used to connect ETWI directly to an actuator (for example,
an electric block, a courtesy light etc.), to control it without passing by a WIEGAND
control unit. If, instead, the actuator is controlled directly by the control unit, leave these
contacts empty. CAUTION! – Due to the fact that these are zero-voltage contacts (i.e.
"dry contacts"), it is necessary to power the connected actuator by using an external
power supply.
This input is used by the control unit to communicate to ETWI that a transmitter has
been detected as "transmitter enabled". In other words, it is used to activate the ETWI
relay. Connect this input to a 12/24V DC digital signal, which comes from the control
unit (warning! - this signal must be properly configured on the control unit).
Connect this input to the WIEGAND D0 line (sometimes also called DATA0 or Data
Low) of the control unit.
Connect this input to the WIEGAND D1 line (sometimes also called DATA1 or Data
High) of the control unit.
Reference for the D0 and D1 lines and for the input INP. Connect this terminal to an
equivalent GND terminal on the control unit.
Input for the ETWI power supply. Must be between 12 and 24V, in direct or alternate
current.
