1 The WAGO I/O System
The WAGO I/O SYSTEM consists of various components which are capable of
providing modular and application specific fieldbus nodes for various fieldbusses.
I11.1 Setting up a fieldbus node with the WAGO I/O SYSTEM
General remark:
A fieldbus node consists in principle of a fieldbus coupler at the front end, a number of
special function modules and a termination module which is placed at the other end.
1 - Buscoupler
The Buscoupler forms the link between the fieldbus and the field devices with their I/O
functions. All control functions required for the faultless operation of the I/O functions
are carried out by the coupler. The connection to different fieldbus systems is
established by each of the corresponding Buscouplers, e.g. for PROFIBUS, INTERBUS
S, II/O LIGHTBUS, CAN, ModBus etc. In this way a change of the fieldbus system is
possible.
2 - Function modules
In the function modules, the incoming process data ais converted. Corresponding to the
different requirements, special function modules are available for a variety of functions.
There are digital and analog inputs and outputs and modules for special functions. The
modules are described in the following chapters.
3 - Termination module
A termination module is needed for faultless operation of the node. The termination
module is always placed as the last module in order to obtain a termination of the
fieldbus node. This module has no I/O function.

Assembly of the WAGO I/O System
All components of the system can be snapped directly on a carrier rail according to EN
50022 (DIN 35).
When snapping the analog or digital components onto the rail, no special sequence must
be observed. The secure positioning and connection of the individual function modules
and the coupler is provided by a snap-in system. This snap-in system provides automatic
interlocking onto the DIN rail assembly. It is always possible to remove a function
module or the Buscoupler from the assembly by pulling the orange pull-tab.
Please note, that the power supply of the field side as well as the data transmission are
interrupted. It has to be ensured that the interruption of PE will not put personnel or
equipment in danger.
With a CAGE CLAMP, conductors with a cross section of 0.08 to 2.5mm2/AWG 18-14
can be connected. Vibration proof, fast and maintenance-free. You simply introduce a
screwdriver or an operating tool into the operating slot under the clamping unit. The
CAGE CLAMP spring is pressed down. You can now introduce the wire into the
clamping unit. Withdraw the operating tool and the conductor is automatically clamped.
Interbus / Introduction

The clamping force adjusts automatically to the conductor cross section. The flat
clamping face of the CAGE CLAMP spring presses the conductor against the current
bar without damage. Any deformation or movement of the conductor is compensated,
thus eliminating the risk of a loose connection. The contact point between conductor
and CAGE CLAMP is well protected against corrosive deterioration. This connection is
made fast and, furthermore, it is maintenance-free. There is no need for costly periodical
examination of the connections.
The supply modules of the WAGO I/O system are partly equipped with a fuse holder.
This fuse holder can be pulled out in order to break the circuit of the following modules.
To do so, you first have to insert a screwdriver into one of the slots on both sides in
order to pull out the front side of the fuse holder.
The front side now being hinged down makes it possible to remove or to insert the fuse.
After that, you lift up the front side again and push the fuse holder back into its original
position.

Ill. 2: The INTERBUS buscoupler
The 750-304 Interbus coupler consists of two major electronic sub systems:
left side:
This housing contains the electronics for the coupling to the bus, the processor
and the fieldbus connection. (ill. 2.1)
right side:
This housing contains the DC to DC converter and power distribution for the internal K
bus, local processor and external 24 V DC connections to other discrete I/O modules.
Illustration 2.2 identifies the 24 V DC connection points to supply voltage to I/O
modules. Illustration 2.3 identifies the ground connection.
