IP67 sealed interfaces for connecting sensors/actuators using M12 connectors. These distributors enable connection of four traditional non-communicating sensors/actuators on the same AS‐i address. This type of distributor is used very often on existing machines to be renovated as it avoids having to intervene on the installation.

IP67 sealed interfaces for connecting sensors/actuators using M12 connectors. These distributors do not have any electronics and can therefore be used to connect the communicating sensors/actuators. This type of distributor can be used for new machines but has the drawback of using four AS-i addresses.

These passive and active distributors comprise:
-
Photo-electric detectors:
They detect all kinds of objects (opaque, reflective etc) with 5 basic systems: barrier, reflex, polarized reflex, proximity and proximity with background suppression. They offer an IP 67 protection level.
-
Inductive proximity detectors:
They detect all metal objects and provide information for the functions used to check whether an object is present or not. They offer an IP 67 protection level.

These sensors which are fitted with an AS-i ASIC can be directly connected to the AS-i bus or to a passive distributor module. As AS‐i bus slaves, they have 4 parametering bits (P0 to P3) to write information such as time out adjustments; field depth, etc.
The TBX SAP 10 module can modify the value of these slaves during operation.
AS-i dedicated power supplies are designed to supply the components connected to the AS-i bus.
The distribution of this power supply uses the same medium as that used for data exchange.
These
AS-i power supplies can be placed at any given point on the AS‐i bus, but it is advisable to place them nearest the areas that consume the most power. These are 30 VDC power supplies designed to communicate over distances of 100m.
This table presents the various AS-i power supplies:

It transmits both communications data and the power supply to:
It can be made up from:
-
Either an unshielded and polarized, twin-wire AS-i ribbon cable.
-
Or a standard round, shielded or unshielded twin-wire cable.
Illustration:
Under low disturbance conditions, any traditional standard cable (H05VV type) with a cross-section of 1.5 to 2.5 mm2 can be used (depending on the consumption of all the slaves) with distributors that include screw terminal blocks.
Using a dedicated AS-i ribbon cable provides the advantage of being able to immediately connect the AS-i slaves with automatic polarization, using the piercing connector clip-on technique.
The direct motor starters and toggle switches in sealed boxes (IP54 and IP65) ensure electrical motors are controlled and protected up to 4KW at 400 VAC.

Man-Machine Interface Products
-
Button boxes:
These are made up of dialog tools, which are perfectly adapted to exchanging information between the operator and machine.
-
Keyboards:
The man/machine dialog tools have 12 touch sensitive keys. The information delivered is coded in BCD on 4 bits. They offer an IP 65 protection level.

Connecting and branching accessories
T-piece connectors are used to make connections to the AS-i bus. These are designed for linking to AS-i ribbon cables or to ribbon/round cable branches.
