Details: VBA-LT2-G1-2YE


The VBA-LT2-G1 light button module creates a connection between the operating staff and the AS-Interface master. The current status can be seen on the LEDs, which are built into the buttons. There is also an LED for monitoring AS-Interface communication and the display to ensure that the module has 0 as an address.

The light button is designed according to protection type IP67 and is thus suitable for use in the field.

Various bases are available for the module. Base U-G1F implements a connection to the AS-Interface flat cable, while the U-G1P base makes a connection to a round cable.

The case arises very often that output modules must be mounted in series with the light button. The outputs of the output module receive their power supply externally. If this power supply is transferred via a flat cable, the case arises that the power supply line must be mounted in the base of an input module. In this case the U-G1FF base should be used. Then the VAA-LT2-G1 accesses the AS-Interface line, but not the power supply line.
