BUSLINK - AS-Interface INSTALLATION

AS-INTERFACE (AS-Interface)

Pneumatic spool valve island for data exchange via field bus
and standardized AS-Interface protocol.

The connection between a control system (PLC) and several spool
valve islands by means of a field bus allows the transmission of data
with a standard AS-Interface cable :

• control signals to the spool valves,

• information signals from the sensor inputs.

ADVANTAGES

With the many advantages it offers, the Buslink system meets
modern needs for automated installations.

• No bulky and difficult wiring.

• Time and money saved due to direct electric cabling and common
air supply.

• Visual display and quick disconnection for easy maintenance.

• Unit tested and equipped with spool valves at delivery.

INSTALLATION BUSLINK - AS-Interface

2. SYSTEM COMPONENTS

2.1 FUNCTIONAL DESCRIPTION

The spool valve islands are connected to a PLC with a (yellow) AS-Interface bus cable to pilot the spool valves and detect the sensor
status if the island is provided with inputs. A second adapter is used to supply the valves with power (black cable).

The pressure supply and exhaust are collected in the pneumatic subbase. The spool valves ensure the pressure supply and exhaust
of the pneumatic actuators. The pneumatic connection of the actuators is made on the top side of the spool valves. The island can be
equipped with inputs upon request. The electrical sensors are connected to the input modules with male connectors ØM12.

MAXIMUM CAPACITY OF THE SPOOL VALVE ISLAND

According to the configuration you choose, the islands can be equipped with a maximum of 8 inputs and 8 outputs (1 output = 1 spool
valve pilot).
The maximum capacity of the island depends on the number of nodes (see table below).

Example for maximum configuration:

Number

of nodes

Max. number

of valves

4 monostable

or 2 bistable

or 2 double 3/2 NC

8 monostable

or 4 bistable

or 4 double 3/2 NC

or 4 monostable +

Max. number

NOTE:

- Maximum configuration for 1 node

: 4 outputs / 4 inputs

- Maximum configuration for 2 nodes: 8 outputs / 8 inputs

- 1 output = 1 monostable spool valve

- 2 outputs = 2 monostable spool valves or 1 bistable spool
valve

(1) In this configuration, the bistable spool valves are

always to be placed on the right-hand side of the island.

2.3 DIMENSIONS - MOUNTING

The island is provided with four mounting holes in the
spool valve subbase and two mounting holes on the
left side for input/output modules. The centre distance
L2 is dependent on the number and size of the spool
valves.

Total length of spool valve island: L2 + 77

Make sure to provide for enough room on the right
side for pressure supply and optional exhaust
silencers.

- Threaded connection directly on the spool valve body.

- With instant fittings for flexible hose (for valve series 569 and 570).

■■

■ Connecting instructions

■■

- Remove all protective plastic caps.

- Insert the gasket which generally comes with the ØM5 connectors or banjo-type screw-fittings.

- Screw down the connectors and screw-fittings correctly.

- Screw in the exhaust silencers.

- Connect the pneumatic piping. Gather the tubes in order to have neat and accessible piping.

A maximum of five spool valves can be operated at the same time without pneumatic malfunction.

- Island with 8 spool valves

The pressure on an island with more than 6 spool valves must be supplied from both sides.
For this purpose, all islands for 8 to 16 spool valves are equipped with a connecting flange.

4 ELECTRICAL CONNECTION

4.1 GENERAL

The islands are equipped with 2 vampire-type AS-Interface connectors to connect the bus network and power supply (B).
Upon request, the subbases can also be provided with two or four 5-pin female panel connectors M12 for the inputs (A).
Cables and M12 connectors must be supplied separately.

Integrated protection circuit for each coil.

Grounding

Grounding for personal protection is

V N.N

effected directly on the island with the
ground screw.

4.2 VOLTAGE SUPPLY

- The yellow cable is used to supply the AS-Interface.

- The black cable is used to supply the valves and inputs.

Supply voltage : 24 VDC, ±10%
Max. ripple ratio : ±10 %
Consumption : 1.7 per coil, + 0.2 W per LED

max. 5 W / bus electronics
Inputs: total value < 0.5 A
Calculation of power draw (see below).
Check the supply voltage during operation and make sure the admissible tolerance (±10%) is observed.

4.3 CALCULATION OF POWER DRAW

The island's power draw depends on its configuration.
Calculating this power draw will allow the user to provide for optimal 24 V power supply.
Consumption of the different elements:

- Consumption of bus electronics : 40 mA

- Consumption of one input : 9 mA

- Consumption of one valve + LED : 79 mA
