• 2.6.5 The WAGO-I/O-SYSTEM 750 Mechanical Setup 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 coupler/controller 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.
Assembly Sequence WAGO DIN Rail 2.6.6 • 25 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 coupler/controller, the bus modules are assembled adjacent to each other according to the project planning.
• 2.6.7 The WAGO-I/O-SYSTEM 750 Mechanical Setup Internal Bus/Data Contacts Communication between the coupler/controller 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.
Power Contacts WAGO DIN Rail 2.6.8 • 27 Power Contacts Self-cleaning power contacts , are situated on the side of the components which further conduct the supply voltage for the field side. These contacts come as touchproof spring contacts on the right side of the coupler/controller and the bus module. As fitting counterparts the module has male contacts on the left side. Danger The male contacts are sharp-edged. Handle the module carefully to prevent injury.
• 2.6.9 The WAGO-I/O-SYSTEM 750 Mechanical Setup Wire Connection All components have CAGE CLAMP® connections. The WAGO CAGE CLAMP® connection is appropriate for solid, stranded and finely 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.
Isolation WAGO DIN Rail • 29 2.7 Power Supply 2.7.1 Isolation Within the field bus node, there are three electrically isolated potentials. Operational voltage for the field bus interface. Electronics of the couplers/controllers and the bus modules (internal bus). All bus modules have an electrical isolation between the electronics (internal bus, logic) and the field electronics. Some digital and analog input modules have each channel electrically isolated, please see catalog. Fig.
• The WAGO-I/O-SYSTEM 750 Power Supply 2.7.2 2.7.2.1 System Supply 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 coupler/controller 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.
System Supply Alignment • 31 Attention Resetting the system by switching on and off the system supply, must take place simultaneously for all supply modules (coupler/controller 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 WAGO-I/O-SYSTEM 750 Power Supply Example: A node with a PROFIBUS Coupler 750-333 consists of 20 relay modules (750-517) and 10 digital input modules (750-405). Current consumption: 20* 90 mA = 1800 mA 10* 2 mA = 20 mA Sum 1820 mA The coupler can provide 1650 mA for the bus modules. Consequently, an internal system supply module (750-613), e.g. in the middle of the node, should be added.
Field Supply Connection 2.7.3 Field Supply 2.7.3.1 Connection • 33 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 coupler/controller provides field side power (DC 24V). In this case it is a passive power supply without protection equipment.
• The WAGO-I/O-SYSTEM 750 Power Supply 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.
Field Supply Fusing • 35 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. Fig.
• The WAGO-I/O-SYSTEM 750 Power Supply Alternatively, fusing can be done externally. The fuse modules of the WAGO series 281 and 282 are suitable for this purpose. Fig. 2-18: Fuse modules for automotive fuses, series 282 pf66800x Abb. 2-19: Fuse modules for automotive fuses, series 2006 p0xxx13x Fig. 2-20: Fuse modules with pivotable fuse carrier, series 281 pe61100x Abb.
Supplementary Power Supply Regulations Fusing 2.7.4 • 37 Supplementary Power Supply Regulations The WAGO-I/O-SYSTEM 750 can also be used in shipbuilding or offshore and onshore areas of work (e. g. working platforms, loading plants). This is demonstrated by complying with the standards of influential classification companies such as Germanischer Lloyd and Lloyds Register. Filter modules for 24-volt supply are required for the certified operation of the system. Item No.
2.7.5 The WAGO-I/O-SYSTEM 750 Power Supply Supply Example Attention The system supply and the field supply should be separated in order to ensure bus operation in the event of a short-circuit on the actuator side.
Power Supply Unit Fusing 2.7.6 • 39 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 %. 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. 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 WAGO-I/O-SYSTEM 750 Grounding 2.8 Grounding 2.8.1 2.8.1.1 Grounding the DIN Rail 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.
Grounding Function Insulated Assembly 2.8.2 • 41 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. 2-24: 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.
• 2.8.3 The WAGO-I/O-SYSTEM 750 Grounding 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.
General Insulated Assembly • 43 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.
• 2.9.4 The WAGO-I/O-SYSTEM 750 Assembly Guidelines/Standards WAGO Shield (Screen) Connecting System The WAGO Shield Connecting system includes a shield clamping saddle, a collection of rails and a variety of mounting feet.

INTERBUS • 77 5 INTERBUS 5.1 Overview INTERBUS is standardized as a fieldbus in EN 50 254. This bus is set up as a data ring with a central bus master linked to bus slaves. There are several types of INTERBUS variants, with two fieldbus variants listed here for decentralized periphery: Remote bus Installation remote bus 5.1.1 Remote Bus Features 1 Master, up to 256 Slaves Ring structure with active coupling of subscribers Max. length of fieldbus segment 400 m / 150 m Max. expansion 12.
• INTERBUS 5.1.2 Description The physical structure of the bus is set up as a point-to-point link between the subscribers. Each subscriber has an "incoming" bus and an "outgoing" bus. Remote bus Master Remote bus device Remote bus segment Bus coupler Remote bus device Remote bus device Remote bus device Remote bus device Fig.
INTERBUS • 79 The subscribers are assigned their address automatically based on their physical position in the bus system. Control signals (CLOCK, RESET, SELECT, CONTROL) allow each single subscriber to be monitored. Each subscriber has its own ID register that contains information about the type of module, number of I/O addresses and status and error status data. The INTERBUS uses two operating modes: 1.
• INTERBUS 5.2 Interface Modules Master operation is performed by a central control system, such as PLC, NC or RC. The fieldbus devices are linked via interface modules. Interface modules for programmable logic controllers (PLCs) and PC interface cards are available from different manufacturers for INTERBUS. 5.3 Configuration Software The interface modules must be configured with the specific station data to enable links to be set up between the PLC and the fieldbus devices.
