ASi Illuminated Button Module

Key Features

• Empty housing for up to 6 built-in buttons, built-in lamps or similar with diameter 22 mm.
• Connection of illuminated pushbuttons via pluggable screw terminals.
• Degree of protection IP65 possible.
• Integrated communication monitoring function.
• Inputs and outputs short-circuit and overload proof.
• No external power supply required.
• M12 plug for simple connection to AS-Interface.

Function

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 by means of an additional printed circuit board module VAA-4E4A-CB1-Z/E2.

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

Application

LED displays should be used preferably, in order to avoid an exceeding of the maximum current.

Dimensions

The module is a rectangular unit with the following approximate dimensions:

• Height: 180 mm
• Width: 165 mm

Connection Diagram

The connection diagram shows the AS-Interface bus connection with terminals for AS-Interface + and AS-Interface -. It details the internal circuitry connecting these to the module's inputs (IN1-IN4) and outputs (OUT1-OUT4). The module supports 4 inputs and 4 outputs.

Assembly

The assembly diagram illustrates the internal structure of the module. It shows the AS-Interface connection points (pins 1 and 2) and the internal circuit board, which includes connections for inputs (IN1-IN4, pins 4-7) and outputs (OUT1-OUT4, pins 10-13). The diagram also indicates the interface for connecting a display unit.
