2.4. Functional Overview
This manual describes the e.bloxx module A5-1CR. This module is an 8-channel module (real plus virtual).
Each e.bloxx module has 8 channels that can be defined, the other channels can be used to do arithmetical calculations
or process the measured value (scaling, min/max, alarm), to preset a certain value that can be changed later via
interface and for threshold monitoring. The channels are defined in the configuration table of the Configuration Software
ICP 100.
2.5. Front-LED
The LED at the front of the e.bloxx modules provides the following information:
LED green Module works well, no signal overflow, no communication error…
LED red general error like signal overflow, broken sense leads
LED red + short off period general error like signal overflow, broken sense leads + communication timeout
LED green + short red flash Signal ok + communication timeout
LED red fast flashing global error, no suitable firmware
Notice: The LED will get red when the signal leaves the selected range and the error checking is activated
(see ICP 100 column Range/Error).
2.6. DC-Isolation
The power supply, bus interface, analog inputs are DC-isolated from each other.

MOUNTING e.bloxx AND CONNECTING WIRES
12 HB_EBLOXX-A5CR_E_V11.doc
Gantner Instruments Test & Measurement GMBH
3. MOUNTING e.bloxx AND CONNECTING WIRES
3.1. Environmental Conditions
The e.bloxx modules are protected against water and dirt according IP 20. If required by the conditions of the operating
site the modules have to be installed accordingly, e.g. in a water-resistant or water-proof case, compliant with the
regulations of electrical engineering.
For the allowed ambient temperatures for the e.bloxx A5-1CR see the Technical Specifications at the end of this
manual.
3.2. Connection Technique
The wires are connected to the modules via screw-type terminals. The captive terminal screws are part of the terminal
strips. All terminal strips are of plug-in type and can be detached from the modules.
Not more than 2 leads should be connected with one clamp. In this case both leads should have the same conductor
cross-section. For the precise clamping of stranded wire we recommend the use of wire-end ferrules.
Notice: Connecting wires respectively the plugging-in and -out of the terminal strip is only allowed with modules in
power-off status.
In order to prevent interference with sensors, signals and modules, shielded cables have to be used for the
power supply, bus connection and signal lines.
We strongly recommend using a single screened cable each input signal. To use more signals in one cable
could generate interacting influences.
Notice: For optimal performance the e.bloxx modules must be grounded properly. This is achieved by utilizing the
Ground/Earth screw on the back of each e.bloxx module. The screen of the sensor cable has to be grounded
at the same potential.
3.3. Power Supply
Non-regulated DC voltage between +10 and +30 VDC is sufficient for the power supply of the modules. The input is
protected against excess voltage and polarity connecting error. The power consumption remains approximately constant
over the total voltage range, due to the integrated switching regulator.
Due to their low current consumption the modules can also be remotely supplied via longer lines. Several modules can
be supplied in parallel within the permissible voltage range and drop in the lines. If required, the supply lines together
with the bus line may be incorporated in one cable.
In order not to overload the module power supply needlessly and to avoid unnecessary line troubles, a separate power
supply is recommended for sensors with a large current drain.
The distribution voltage for the e.bloxx modules has to be protected by a fuse with maximum 1 A (inert). The modules
have an internal fuse (reversible) for protection against excess voltage, excess current and wrong polarity.

Notice: It depends on the power supply unit and its noise and internal grounding issues whether it is helpful to
connect earth of the power supply unit with ground/earth of the e.bloxx module.
Picture 3.1. - Power Supply of the e.bloxx Modules
3.4. Bus Connection
Only the connection of the e.bloxx modules to the bus is described in here. A detailed description of the bus and the
communication of the modules can be found in the Communication Guide of the e.bloxx/e.gate modules.
The e.bloxx modules have an RS 485 bus interface for connection to the serial fieldbus. The bus has to be terminated
on both sides with a characteristic impedance. The maximum line length depends on the transmission speed (refer to
the Communication Guide for details) and can never be higher than 1.2 km per bus segment or 4.8 km via a physical
bus string by using 3 repeaters. A maximum of 32 devices are possible with each bus segment and up to 127 devices
via a physical bus string.
Wiring
In general, the e.bloxx is connected to the bus by connecting both signal leads A and B of the incoming bus cable and
A' and B' of the outgoing bus cable together to one terminal on the module (Picture 3.2). Alternatively, the bus can also
be connected by a "stub cable" (Picture 3.3). This guarantees that the bus connection to other modules remains in
place, even if one module has to be exchanged, due to the removable terminal strip.

Picture 3.3. - Bus Connection of an e.bloxx A5-1CR to the RS 485 Fieldbus via Stub Cable
The stub-cable should be as short as possible, not longer than 30 cm.
Notice: The terminal designations A and B of all modules of the e.bloxx series are exchanged compared with the
PROFIBUS-definitions. Consequently, in multi-vendor systems the bus lines A and B have to be exchanged
when connecting them to the e.bloxx.
Bus Structure
The bus structure is a line structure where each bus segment will be terminated with an characteristic impedance on
both ends. Branches can be set up by means of a bi-directional signal amplifier, so-called repeaters. Other types of
branches are not permitted (no tree topology). The max. stub-length to a user may not exceed 30 cm.
The following figures show a few examples of possible bus topology structures. The meanings of the symbols are as
follows:

* ... If the e.bloxx A5-1CR is used together with an e.gate, which is used to collect the data of all connected e.bloxx
modules and processes them for fast transmission via the further network, a bus termination must be connected to the
last e.bloxx in each bus line.
Bus Connection to PC
The bus interface of the e.bloxx is based on the RS 485 standard. Since most hosts are "only" equipped with RS-232
interfaces, an interface converter or a plug-in board with RS 485 drivers is required for conversion purposes.
Gantner Instruments Test & Measurement GMBH offers a compact interface converter, called ISK 200, with an inte-
grated power supply and automatic baud rate detection. The power supply, bus connection and a separate 24 VDC-
output are DC-isolated. Therefore, the interface converter ISK 200 is also applicable as a power supply for remote
applications. Additionally, the interface converter ISK 200 features the option of connecting the required bus termination
via a switch. The converter is designed to be used as a desk device.
Another module IRK 100 from Gantner Instruments Test & Measurement GMBH is available which may be used as an
RS 485 repeater or RS 485/RS 232 converter. The baud rate can be adjusted at the IRK 100. Also, for this module the
required bus termination may be connected with a switch. The Repeater/ Converter IRK 100 has a snap-on mounting
mechanism for the installation on standard profile rails (DIN rail) 35 mm according to DIN EN 50022.

Table 3.1. - Pin Assignment D-Subminiature Plug According to PROFIBUS
The signal leads A and B (and Shield) are mandatory for a (shielded) connection. Additional signal leads may be
installed if required.
Notice: Due to the fact that the RS 485 interface is used for different protocols, in case of using Profibus-DP the
leads A and B has to be crossed.
Bus Termination at the e.bloxx Modules
In order to avoid signal reflections on the bus, each bus segment has to be terminated at its physical beginning and at
its end with the characteristic impedance. A terminating resistor is installed between the bus leads A and B for this
purpose. In addition, the bus lead A is connected via a pull-up resistor to potential (VP) and the bus lead B is connected
via a pull-down resistor to ground (DataGround). These resistors provide a defined quiescent potential in case there is
no data transmission on the bus. This quiescent potential is level high.
The e.bloxx modules have built in these bus termination resistors. They can be connect to the bus by plugging the Bus
Termination Plug IBT 100, which is available as accessory, into the rapid bus link plug on the front side of the module.
Instead of the bus termination plug IBT 100, also separate jumpers may be used for the bus termination. In this case, it
is mandatory that the jumper clips are installed as indicated below, and that the bus leads or the bus termination are not
short-circuited by mistake.

3.5. Shielding
In case of increased interference, such as in industrial areas, we recommend shielding of bus and signal cables. In
general, the shield should be connected to the protective grounding (not DataGround!) at each bus connection. If
necessary, the shield should also be applied along the course of the cable several times. For shorter distances, e.g. with
stub cables, the interference response is often improved if the shielding is only applied to the stub cable exit.
Bus users such as controllers (PLCs), computers (PCs), repeaters and interface converters (ISK), etc., generally feature
the possibility of applying the shield directly to the appliance or to separate shield rails. Shield rails offer the advantage
of preventing possible interfering signals from reaching the appliance. The shields, which are connected to protective
grounding, conduct interference signals off before reaching the module.
The e.bloxx do not have a direct shield connection at the module. Here the shield of the bus cable can be connected to
earth e.g. by so-called shield clamps.

Notice: The shielding screen must not be connected to the ground (0V) of the power supply and it should always be
connected to earth with a large surface and low-inductance.
3.6. Rapid Bus Link Plug
The e.bloxx have plugs on the left and right side which allow to connect the bus and power supply from one module to
the next with a Rapid Bus Link Plug (type designation: ICM 100). This novel kind of connecting bus and power supply is
particularly advantageous if several modules are mounted on one common profile rail side by side. In this case, only the
terminal of one module has to be connected. Furthermore, various modules of the e.bloxx series may be connected with
the Rapid Bus Link Plug.
Notice: The current flowing through the Rapid Bus Link Plug Jack and the e.bloxx must not exceed 1 A. Thus, the
power supply should preferably be connected to the middle of several modules and no more than 6 pieces of
e.bloxx may be connected via the Rapid Bus Link Plug ICM 100 in one line.
