2 The WAGO-I/O-SYSTEM 750

2.1 System Description

The WAGO-I/O-SYSTEM 750 is a modular, fieldbus independent I/O system. In this description, it is comprised of an ECO fieldbus coupler (1) and up to 64 connected fieldbus modules (2) for any type of signal. Together, these make up the fieldbus node. The end module (3) completes the node.

Fig. 2-1: Fieldbus node g0xxx14x

ECO Couplers for fieldbus systems such as PROFIBUS, INTERBUS, CANopen and DeviceNet are available.

The ECO coupler contains the fieldbus interface, electronics and a power supply for the system. The fieldbus interface forms the physical interface to the relevant fieldbus. The electronics process the data of the bus modules and make it available for the fieldbus communication. The 24 V system supply is fed in via the voltage supply.

The ECO coupler is primarily conceived for applications with digital I/O functions. In addition, modules for most different digital and analog I/O functions as well as special functions can be connected to the ECO coupler. The communication between the ECO coupler and the bus modules is carried out via an internal bus.

The WAGO-I/O-SYSTEM 750 has a clear port level with LEDs for status indication, insertable mini WSB markers and pullout group marker carriers. The 3-wire technology supplemented by a ground wire connection allows for direct sensor/actuator wiring.

18 • The WAGO-I/O-SYSTEM 750 Storage, Assembly and Transport

2.5 Storage, Assembly and Transport

Wherever possible, the components are to be stored in their original packaging. Likewise, the original packaging provides optimal protection during transport.

When assembling or repacking the components, the contacts must not be soiled or damaged. The components must be stored and transported in appropriate containers/packaging. Thereby, the ESD information is to be regarded.

Statically shielded transport bags with metal coatings are to be used for the transport of open components for which soiling with amine, amide and silicone has been ruled out, e.g. 3M 1900E.

2.6 Mechanical Setup

2.6.1 Installation Position

Along with horizontal and vertical installation, all other installation positions are allowed.

Attention In the case of vertical assembly, an end stop has to be mounted as an additional safeguard against slipping. WAGO item 249-116 End stop for DIN 35 rail, 6 mm wide WAGO item 249-117 End stop for DIN 35 rail, 10 mm wide

2.6.3 Assembly onto Carrier Rail

2.6.3.1 Carrier rail properties

All system components can be snapped directly onto a carrier rail in accordance with the European standard EN 50022 (DIN 35).

Warning WAGO supplies standardized carrier rails that are optimal for use with the I/O system. If other carrier rails are used, then a technical inspection and approval of the rail by WAGO Kontakttechnik GmbH should take place.

Carrier rails have different mechanical and electrical properties. For the optimal system setup on a carrier rail, certain guidelines must be observed:

• The material must be non-corrosive.

• Most components have a contact to the carrier rail to ground electro-

magnetic disturbances. In order to avoid corrosion, this tin-plated carrier rail contact must not form a galvanic cell with the material of the carrier rail which generates a differential voltage above 0.5 V (saline solution of

0.3% at 20°C) .

• The carrier rail must optimally support the EMC measures integrated into the system and the shielding of the bus module connections.

• A sufficiently stable carrier rail should be selected and, if necessary, several mounting points (every 20 cm) should be used in order to prevent bending and twisting (torsion).

• The geometry of the carrier rail must not be altered in order to secure the safe hold of the components. In particular, when shortening or mounting the carrier rail, it must not be crushed or bent.

• The base of the I/O components extends into the profile of the carrier rail. For carrier rails with a height of 7.5 mm, mounting points are to be riveted under the node in the carrier rail (slotted head captive screws or blind rivets).

2.6.4 Spacing

The spacing between adjacent components, cable conduits, casing and frame sides must be maintained for the complete field bus node.

Fig. 2-4: Spacing g01xx13x

The spacing creates room for heat transfer, installation or wiring. The spacing to cable conduits also prevents conducted electromagnetic interferences from influencing the operation.

2.6.5 Plugging and Removal of the Components

Warning Before work is done on the components, the voltage supply must be turned off.

In order to safeguard the ECO coupler from jamming, it should be fixed onto the carrier rail with the locking disc. To do so, push on the upper groove of the locking disc using a screwdriver.

To pull out the ECO fieldbus coupler, release the locking disc by pressing on the bottom groove with a screwdriver and then pulling the orange colored unlocking lug.

Fig. 2-5: Coupler and unlocking lug g0xxx18e

It is also possible to release an individual I/O module from the unit by pulling an unlocking lug.

Fig. 2-6: removing bus terminal p0xxx01x

Danger Ensure that an interruption of the PE will not result in a condition which could endanger a person or equipment! For planning the ring feeding of the ground wire, please see chapter 2.6.3.

22 • The WAGO-I/O-SYSTEM 750 Mechanical Setup

2.6.6 Assembly Sequence

All system components can be snapped directly on a carrier rail in accordance with the European standard EN 50022 (DIN 35).

The reliable positioning and connection is made using a tongue and groove system. Due to the automatic locking, the individual components are securely seated on the rail after installing.

Starting with the ECO coupler, the bus modules are assembled adjacent to each other according to the project planning. Errors in the planning of the node in terms of the potential groups (connection via the power contacts) are recognized, as the bus modules with power contacts (male contacts) cannot be linked to bus modules with fewer power contacts.

Attention Always link the bus modules with the ECO coupler, and always plug from above.

Warning Never plug bus modules from the direction of the end terminal. A ground wire power contact, which is inserted into a terminal without contacts, e.g. a 4-channel digital input module, has a decreased air and creepage distance to the neighboring contact in the example DI4.

Always terminate the fieldbus node with an end module (750-600).

2.6.7 Internal Bus / Data Contacts

Communication between the ECO coupler and the bus modules as well as the system supply of the bus modules is carried out via the internal bus. It is comprised of 6 data contacts, which are available as self-cleaning gold spring contacts.

Fig. 2-7: Data contacts p0xxx07x

Warning Do not touch the gold spring contacts on the I/O modules in order to avoid soiling or scratching!

ESD (Electrostatic Discharge) The modules are equipped with electronic components that may be destroyed by electrostatic discharge. When handling the modules, ensure that the environment (persons, workplace and packing) is well grounded. Avoid touching conductive components, e.g. gold contacts.

24 • The WAGO-I/O-SYSTEM 750 Mechanical Setup

2.6.8 Power Contacts

Self-cleaning power contacts , are situated on the side of some components which further conduct the supply voltage for the field side. These contacts come as touchproof spring contacts on the right side of the bus modules. As fitting counterparts the module has male contacts on the left side.

Danger The power contacts are sharp-edged. Handle the module carefully to prevent injury.

Attention Please take into consideration that some bus modules have no or only a few power jumper contacts. The design of some modules does not allow them to be physically assembled in rows, as the grooves for the male contacts are closed at the top.

Fig. 2-8: Example for the arrangement of power contacts g0xxx05e

Recommendation With the WAGO ProServe® Software smartDESIGNER, the assembly of a fieldbus node can be configured. The configuration can be tested via the integrated accuracy check.

2.6.9 Wire connection

All components have CAGE CLAMP® connections. The WAGO CAGE CLAMP® connection is appropriate for solid, stranded

and fine–stranded conductors. Each clamping unit accommodates one conductor.

Fig. 2-9: CAGE CLAMP® Connection g0xxx08x

The operating tool is inserted into the opening above the connection. This opens the CAGE CLAMP

. Subsequently the conductor can be inserted into the opening. After removing the operating tool, the conductor is safely clamped.

More than one conductor per connection is not permissible. If several conductors have to be made at one connection point, then they should be made away from the connection point using WAGO Terminal Blocks. The terminal blocks may be jumpered together and a single wire brought back to the I/O module connection point.

Attention If it is unavoidable to jointly connect 2 conductors, then a ferrule must be used to join the wires together. Ferrule: Length 8 mm Nominal cross section

2.7.1 Isolation

Within the fieldbus node, there are three electrically isolated potentials.

• Operational voltage for the fieldbus interface.

• Electronics of the ECO coupler and the bus modules (internal bus).

• All bus modules have an electrical isolation between the electronics (inter-

nal bus, logic) and the field electronics. Some analog input modules have each channel electrically isolated, please see catalog.

Attention The ground wire connection must be present in each group. In order that all protective conductor functions are maintained under all circumstances, it is recommended that a ground wire be connected at the beginning and end of a potential group. (ring format, please see chapter "2.8.3"). Thus, if a bus module comes loose from a composite during servicing, then the protective conductor connection is still guaranteed for all connected field devices.

When using a joint power supply unit for the 24 V system supply and the 24 V field supply, the electrical isolation between the internal bus and the field level is eliminated for the potential group.

2.7.2 System Supply

2.7.2.1 Connection

The WAGO-I/O-SYSTEM 750 requires a 24 V direct current system supply (-15% or +20 %). The power supply is provided via the ECO coupler and, if necessary, in addition via the internal system supply modules (750-613). The voltage supply is reverse voltage protected.

Attention

The use of an incorrect supply voltage or frequency can cause severe damage to the component.

Fig. 2-11: System Supply g0xxx16e

The direct current supplies all internal system components, e.g. ECO coupler electronics, fieldbus interface and bus modules via the internal bus (5 V system voltage). The 5 V system voltage is electrically connected to the 24 V system supply.

Attention Resetting the system by switching on and off the system supply, must take place simultaneously for all supply modules (ECO coupler and 750-613).

2.7.2.2 Alignment

Recommendation A stable network supply cannot be taken for granted always and everywhere. Therefore, regulated power supply units should be used in order to guarantee the quality of the supply voltage.

The supply capacity of the ECO coupler or the internal system supply module (750-613) can be taken from the technical data of the components.

Internal current consumption*)

Residual current for bus terminals*)

*) cf. catalogue W4 Volume 3, manuals or Internet Example ECO Coupler:

Current consumption via system voltage: 5 V for electronics of the bus modules and ECO coupler

Available current for the bus modules. Provided by the bus power supply unit. See ECO coupler and internal system supply module (750-613)

internal current consumption:350 mA at 5V residual current for bus modules : 650 mA at 5V sum I

: 1000 mA at 5V

(5V) total

The internal current consumption is indicated in the technical data for each bus terminal. In order to determine the overall requirement, add together the values of all bus modules in the node.

Attention If the sum of the internal current consumption exceeds the residual current for bus modules, then an internal system supply module (750-613) must be placed before the module where the permissible residual current was exceeded.

Example:

WAGO-I/O-SYSTEM 750 DeviceNet

A node with a PROFIBUS ECO Coupler consists of 10 relay modules (750-517) and 20 digital input modules (750-405).

Current consumption: 10* 90 mA = 900 mA 20* 2 mA = 40 mA Sum 940 mA

The ECO coupler can provide 650 mA for the bus modules. Consequently, an internal system supp ly module (750-613), e.g. in the middle of the node, should be added.

Page 29

Recommendation With the WAGO ProServe® Software smartDESIGNER, the assembly of a fieldbus node can be configured. The configuration can be tested via the integrated accuracy check.

The maximum input current of the 24 V system supply is 260 mA. The exact electrical consumption (I

Note If the electrical consumption of the power supply point for the 24 V-system supply of the ECO coupler exceeds 260 mA or 500 mA for the 750-613, then the cause may be an improperly aligned node or a defect.

During the test, all outputs, in particular those of the relay modules, must be active.

2.7.3 Field Supply

2.7.3.1 Connection

Sensors and actuators can be directly connected to the relevant channel of the bus module in 1-/4 conductor connection technology. The bus module supplies power to the sensors and actuators. The input and output drivers of some bus modules require the field side supply voltage.

The power supply modules provide field side power (DC 24V). In this case it is a passive power supply without protection equipment. Power supply modules are available for different potentials, e.g. DC 24 V, AC 230 V or others. Likewise, with the aid of the power supply modules, various potentials can be set up. The connections are linked in pairs with a power contact.

Fig. 2-13: Field Supply (Sensor / Actuator) g0xxx17e

Note The 24 V field supply can be connected also directly to a bus module, if the connection points are not needed for the peripheral device supply. In this case, the connection points need the connection to the power jumper contacts

The supply voltage for the field side is automatically passed to the next module via the power jumper contacts when assembling the bus modules .

The current load of the power contacts must not exceed 10 A on a continual basis. The current load capacity between two connection terminals is identical to the load capacity of the connection wires.

WAGO-I/O-SYSTEM 750 DeviceNet

Page 31

The WAGO-I/O-SYSTEM 750 • 31 Power Supply

By inserting an additional power supply module, the field supply via the power contacts is disrupted. From there a new power supply occurs which may also contain a new voltage potential.

Attention Some bus modules have no or very few power contacts (depending on the I/O function). Due to this, the passing through of the relevant potential is disrupted. If a field supply is required for subsequent bus modules, then a power supply module must be used. Note the data sheets of the bus modules.

In the case of a node setup with different potentials, e.g. the alteration from DC 24 V to AC 230V, a spacer module should be used. The optical separation of the potentials acts as a warning to heed caution in the case of wiring and maintenance works. Thus, the results of wiring errors can be prevented.

2.7.3.2 Fusing

Internal fusing of the field supply is possible for various field voltages via an appropriate power supply module.

Warning In the case of power supply modules with fuse holders, only fuses with a maximum dissipation of 1.6 W (IEC 127) must be used.

For UL approved systems only use UL approved fuses.

In order to insert or change a fuse, or to switch off the voltage in succeeding bus modules, the fuse holder may be pulled out. In order to do this, use a screwdriver for example, to reach into one of the slits (one on both sides) and pull out the holder.

2.7.5 Power Supply Unit

The WAGO-I/O-SYSTEM 750 requires a 24 V direct current system supply with a maximum deviation of -15% or +20 %.

A buffer (200 µF per 1 A current load) should be provided for brief voltage dips. The I/O system buffers for approx 1 ms.

The electrical requirement for the field supply is to be determined individually for each power supply point. Thereby all loads through the field devices and bus modules should be considered. The field supply as well influences the bus modules, as the inputs and outputs of some bus modules require the voltage of the field supply.

Note The system supply and the field supply should be isolated from the power supplies in order to ensure bus operation in the event of short circuits on the actuator side.

2.8 Grounding

2.8.1 Grounding the DIN Rail

2.8.1.1 Framework Assembly

When setting up the framework, the carrier rail must be screwed together with the electrically conducting cabinet or housing frame. The framework or the housing must be grounded. The electronic connection is established via the screw. Thus, the carrier rail is grounded.

Attention Care must be taken to ensure the flawless electrical connection between the

2.8.1.2 Insulated Assembly

carrier rail and the frame or housing in order to guarantee sufficient grounding.

Insulated assembly has been achieved when there is constructively no direct conduction connection between the cabinet frame or machine parts and the carrier rail. Here the earth must be set up via an electrical conductor.

The connected grounding conductor should have a cross section of at least

4 mm

Recommendation The optimal insulated setup is a metallic assembly plate with grounding connection with an electrical conductive link with the carrier rail.

The separate grounding of the carrier rail can be easily set up with the aid of the WAGO ground wire terminals.

2.8.2 Grounding Function

The grounding function increases the resistance against disturbances from electro-magnetic interferences. Some components in the I/O system have a carrier rail contact that dissipates electro-magnetic disturbances to the carrier rail.

Fig. 2-22: Carrier rail contact g0xxx10e

Attention Care must be taken to ensure the direct electrical connection between the carrier rail contact and the carrier rail.

The carrier rail must be grounded.

For information on carrier rail properties, please see chapter 2.6.3.2.

38 • The WAGO-I/O-SYSTEM 750 Grounding

2.8.3 Grounding Protection

For the field side, the ground wire is connected to the lowest connection terminals of the power supply module. The ground connection is then connected to the next module via the Power Jumper Contact (PJC). If the bus module has the lower power jumper contact, then the ground wire connection of the field devices can be directly connected to the lower connection terminals of the bus module.

Attention Should the ground conductor connection of the power jumper contacts within the node become disrupted, e.g. due to a 4-channel bus terminal, the ground connection will need to be re-established.

The ring feeding of the grounding potential will increase the system safety. When one bus module is removed from the group, the grounding connection will remain intact.

The ring feeding method has the grounding conductor connected to the beginning and end of each potential group.

Fig. 2-23: Ring-feeding g0xxx07e

Attention The regulations relating to the place of assembly as well as the national regulations for maintenance and inspection of the grounding protection must be observed.

2.9 Shielding (Screening)

2.9.1 General

The shielding of the data and signal conductors reduces electromagnetic interferences thereby increasing the signal quality. Measurement errors, data transmission errors and even disturbances caused by overvoltage can be avoided.

Attention Constant shielding is absolutely required in order to ensure the technical specifications in terms of the measurement accuracy.

The data and signal conductors should be separated from all high-voltage cables.

The cable shield should be potential. With this, incoming disturbances can be easily diverted.

The shielding should be placed over the entrance of the cabinet or housing in order to already repel disturbances at the entrance.

2.9.2 Bus Conductors

The shielding of the bus conductor is described in the relevant assembly guideline of the bus system.

2.9.3 Signal Conductors

Bus modules for most analog signals along with many of the interface bus modules include a connection for the shield.

Note For better shield performance, the shield should have previously been placed over a large area. The WAGO shield connection system is suggested for such an application. This suggestion is especially applicable when the equipment can have even current or high impulse formed currents running through it (for example through atmospheric end loading).
