Details: VAA-LT2-G1


The illuminated pushbutton module VAA-LT2-G1 provides a link between the operating personnel and the AS-Interface master. The current status can be displayed by means of the LEDs integrated in the pushbuttons.

The illuminated pushbutton has IP67 protection and is therefore suitable particularly for use in the field.

Various bases are available for the module. Use the U-G1F base to connect to the ASInterface flat cable, and use the U-G1P base to connect to the round cable.

The output modules often have to be mounted in series with the illuminated pushbutton. The outputs of the output modules are supplied externally with power. If the power is supplied via a flat cable, the power supply lead has to be mounted in the base of the input module. The U-G1FF base should be used in this case. The VAA-LT2-G1 then uses the AS-Interface cable rather than the power cable.
