Function: VAA-LT3-F86-V1

The VAA-LT3-F86-V1 light sensor module creates a connection between the operating personnel and the AS-Interface master. The housing is designed in combination with suitable display and control elements in protection type IP65.

The internal AS-Interface I/O module is ideally suited to integrating customer-specific electronics, for example light sensors or LED lights. The printed circuit board is supplied entirely from the AS-Interface. The inputs and outputs are protected against short circuits and overload and the connection between the display and control elements and the AS-Interface circuit board can be plugged in with screw-on plug-in terminals. The connection to the AS-Interface is implemented by means of a V1 round plug (M12 x 1).

An overloading of the outputs is signalled to the AS-Interface master via the "Peripheral fault" function. Communication via the AS-Interface remains intact.

The luminous push-button module can be expanded to a total of 8 inputs/8 outputs by means of an additional printed circuit board module VAA-4E4A-CB1-Z/E2.


Communication monitoring is integrated. This switches the outputs to a currentless state if no communication is taking place over the AS-Interface cable.
