Valve terminals type 32 MPA

Key features

Individual connection

Valvescan also be used on individual sub-bases for actuators further away from the valve terminal.

Multi-pin plug connection

The signal flow from the controller to the valve terminal takes place via a pre-assembled or self-assembled multi-wire cable to the multi-pin plug connection, which substantially reduces installation time.

AS-interface connection

A special feature of the AS-interface is its ability to simultaneously transmit data and supply power via a two-wire cable. The encoded cable profile prevents connection with incorrect polarity. The valve terminal with AS-interface is available in the following versions:

The electrical connection is established using a standard 4-pin M8 plug (EN 60947-5-2).

The valve terminal can be equipped with max. 24 solenoid coils. This correspondsto4to24MPA1or2to 24 MPA2 valves, or a combination of both.

• With two to eight modular valve positions (max. 8 solenoid coils). This corresponds to 2 to 8 MPA1 or 2to8MPA2valves,ora combination of both.

• With all available valve functions.

Versions

• Sub-D connection

• Pre-assembled multi-pin cable

• Multi-pin cable for self-assembly

The connection technology used for the inputs can be selected as with CPX:M8,M12,Harax,Sub-D, CageClamp® (terminals to IP20).

Further information  Internet: as-interface

CPI installation system

Valve terminal for CPI installation system: Valve terminals with CP connection are intended for connection to higherorder fieldbus nodes or to control blocks. A fieldbus node or control block also enables the connection of decentralised i nput/output units. The following fieldbus protocols are supported:

• Festo fieldbus, ABB CS31, Moeller Suconet K

• Interbus

• Allen Bradley (1771 RIO)

• DeviceNet

• Profibus DP

• Profinet IO

• CC- Li nk

• Modbus/TC P

• Ethernet

• EtherCAT

Four stringswith up to 32 inputs and outputs can be connected to a fieldbus node or control block. The connecting cables transmit the power supply for the input modules and the load voltage for the valves as well as control signals.

Valve terminals type 32 MPA

Key features

Fieldbus connection via the CPX system

An integrated fieldbus node manages communication with a higher-order PLC. This enables a space-saving pneumatic and electronic solution.

Control block connection via the CPX system

Controllers integrated in the Festo valve terminals enable the construction of stand-alone control units to IP65, without control cabinets.

Valve terminalswith fieldbus interfaces can be configured with up to 16 manifold blocks. In conjunction with MPA1 and 8 solenoid coils per manifold block, up to 128 solenoid coils can thus be actuated. An MPA2 with 4 solenoid coils per manifold block can actuate 64 solenoid coils.

Using the slave operation mode, these valve terminals can be used for intelligent pre-processing and are therefore ideal modules for designing decentralised intelligence.

Valve terminals type 32 MPA

Peripherals overview

Modular pneumatic components

The modular design of the MPA facilitates maximum flexibility right from the planning stage and offers maximum ease of service in operation.

The system consists of manifold blocks and valves. The manifold blocks are screwed together and thus form the support system for the valves.

They contain the connection ducts for supplying compressed air to and venting from the valve terminal as well as the working lines for the pneumatic drives for each valve.

Each manifold block is connected to the next using three screws. Individual terminal sections can be isolated and further manifold blocks inserted by loosening these screws. This ensures that the valve terminal can be rapidly and reliably extended.

Modular electrical peripherals

Themannerinwhichthevalvesare actuated differs according to whether youareusingamulti-pinterminal, fieldbus terminal or individual valve. The MPA with CPX interface is based on the internal bus system of the CPX andusesthisserialcommunication system for all solenoid coils and a range of electrical input and output functions.

Sub-base valves can be quickly replaced since the tubing connectors remain on the manifold block. This design is also particularly flat.

Blanking plates can be replaced by valves at a later date. The dimensions, mounting points and existing pneumatic installations remain unchanged during this process.

This pressure regulator regulates the pressure upstream of the valve in duct 1 . Ducts 2 and 4 thus have the same regulatedpressure.

Advantages Application examples

• The pressureregulator is not affected by venting, since the pressure is regulated upstream of the valve.

• The pressureregulator can always be adjusted, since the pressure from the valve terminal is always present.

• An equal working pressure is required at working ports 2 and 4.

During venting,the exhaust flow in the valve is from duct 2 to duct 3 and from duct 4 to duct 5 .

• A l ower working pressure (e.g. 3 bar) than the operating pressure present at the valve terminal (e.g. 8 bar) is required.

Mode of operation of the pressure regulator plate (B regulator)for port 2; code: PC, PH

This pressure regulator regulates the pressure in duct 2 after the pressure medium flows through the valve. During venting,the exhaust flow in the valve is from duct 2 to duct 3 via the pressure regulator.

Restrictions Application example

The pressureregulator can only be adjusted in switched state(e.g. the valve

is switched to 2 and exhaust flow occurs from 4 to 5).

The pressure regulator makes it possible to reduce the pressure at port 2 of an individual valve, i n contrast to

If different working pressures are required at por ts 4 and 2. The pressure presentatport2isfromduct1.

The reversible B regulator splits the supply air in duct 1 and regulates the pressure upstream of the valve in duct 3 (the unregulated pressure from duct 1 is in duct 5). The regulated air is then supplied to duct 2. The valve is thus operated in reversible mode.

During venting,the exhaust flow in the valve is from duct 2 to duct 1 and it is reversed into the manifold block via the intermediate plate to duct 3.

Application examples

• When instead of the operating pressure of the valve terminal, a different pressure is required in duct 2.

• When fast exhaust venting is required.

Advantages Restrictions

• Fast cycle times.

• 50% higher exhaust flow rate, as air
