■ Overview
With the AS-Interface front panel module, 3SB3 control devices,
which are mounted on to the front panels, can be connected
to the AS-Interface bus system. Plastic or metal pushbuttons or
indicator lights in round or square design can be used.
Mushroom pushbuttons and acoustic signaling devices cannot
be used.
The front panel module comprises:
•Slave 4I/4O
• 4 3SB3 commanding and signaling devices
• Accessories (lamps, name plates, mounting parts)
The selection of standard fittings is made through the ordering
documents (see next page).
The front panel module is mounted on the back of the front panel
on a group of four actuators and indicators arranged alongside
or on top of each other and secured with screws. The contact
blocks and lampholders are integrated in the module.
A 30 mm x 45 mm grid must be considered when mounting the
control devices on to the front plate.
Connection to the AS-Interface shaped cable is by means of a
terminal positioned on the rear of the module using the insulation
piercing method.
Addressing is performed using the AS-Interface connections or
the integrated addressing socket.
