ETAS Introduction
1 Introduction
This User’s Guide describes the ES4435.1 Current Source Load Board.
It consists of the following chapters:
• "Introduction" on page 5
This chapter – here you will find general information on the ES4435.1
Current Source Load Board.
• "Hardware" on page 11
This chapter describes the individual function units of the ES4435.1 Cur-
rent Source Load Board in more detail.
• "Technical Data" on page 15
This section contains the technical data of the ES4435.1 Current Source
Load Board
CAUTION!
Some components of the ES4435.1 Current Source Load Board may
be damaged or even destroyed by static discharge. Leave the board in
its transport package until you want to install it.
The ES4435.1 Current Source Load Board should only be taken from
its package, configured and installed at a working place that is pro-
tected against static discharge.
WARNING!
The components, connectors and conductors of the ES4435.1 Cur-
rent Source Load Board may carry dangerous voltages. These voltages
may even exist if the ES4435.1 is not installed in the ES4408.1 Load
Chassis or the ES4408.1 Load Chassis is powered off.
Make sure the ES4435.1 is protected against contact during opera-
tion.
CAUTION!
If cards are unlocked (e.g. during setup or calibration) but not com-
pletely removed from the housing, they nevertheless have to be
pulled out of the housing so that the distance between the card and
the backplane of the housing is at least 1 cm! Otherwise there could
be contacts between the cards which could then be destroyed as a
result.

Introduction ETAS
1.1 Features
The ES4435.1 Current Source Load Board is a 3 U plug-in board for the ES4408.1
Load Chassis and is used to simulate low current loads up to 150 mA.
A total of seven boards of the type ES4434.1 Configurable Load Board and
ES4435.1 Current Source Load Board can be installed in the ES4408.1 Load
Chassis.
The ES4435.1 Current Source Load Board has the following features:
• 24 current sources
• Current direction can be set for every current source in LABCAR-RTC
• Every current source can drive currents of 5...150 mA (at 6 V...20 V bat-
tery voltage)
• Power limitation 3 W/current source – with higher battery voltages (up to
60 V max.) the maximum permissible current will be limited accordingly
• Current sources are enabled/disabled depending on the status of a spe-
cific battery node – sources are also assigned to battery nodes in LABCAR-
RTC.
This makes the ES4435.1 Current Source Load Board suitable for projects in
which frequent reconfigurations are necessary – for rare changes, we would rec-
ommend the ES4434.1 Configurable Load Board which can accommodate 24
manually configurable loads.

Introduction ETAS
1.2 Basic Safety Instructions
Please adhere to the safety instructions in this manuals to avoid injury to yourself and
others as well as damage to the device.
1.2.1 Correct Use
ETAS GmbH cannot be made liable for damage which is caused by incorrect use and not
adhering to the safety instructions.
1.2.2 Labeling of Safety Instructions
The safety instructions contained in this manual are shown with the standard danger sym-
bol shown below:
The following safety instructions are used. They provide extremely important information.
Please read this information carefully.
CAUTION!
indicates a low-risk danger which could result in minor or less serious injury
or damage if not avoided.
WARNING!
indicates a possible medium-risk danger which could lead to serious or even
fatal injuries if not avoided.
DANGER!
indicates a high-risk, immediate danger which could lead to serious or even
fatal injuries if not avoided.

1.3 Identifications on the Product
The following Symbols are Used for Product Labeling:
1.3.1 KC Mark
With the KC mark attached to the product and its packaging, ETAS confirms that
the product has been registered in accordance with the product-specific KCC
guidelines of the Republic of Korea.
Symbol Description
Marking for KCC conformity
(see "KC Mark" on page 9)
Marking for conformity with WEEE directive
(see "Taking the Product Back and Recycling" on page 10)

Introduction ETAS
1.4 Taking the Product Back and Recycling
The European Union has passed a directive called Waste Electrical and Electronic
Equipment, or WEEE for short, to ensure that systems are setup throughout the
EU for the collection, treating and recycling of electronic waste.
This ensures that the devices are recycled in a resource-saving way representing
no danger to health or the environment.
Fig. 1-2 WEEE Symbol
The WEEE symbol on the product or its packaging shows that the product must
not be disposed of as residual garbage.
The user is obliged to collect the old devices separately and return them to the
WEEE take-back system for recycling.
The WEEE directive concerns all ETAS devices but not external cables or batteries.
For more information on the ETAS GmbH Recycling Program, contact the ETAS
sales and service locations (see "ETAS Contact Addresses" on page 17).

This chapter describes the individual function units of the ES4435.1 Current
Source Load Board in more detail.
These are:
• "Current Sources" on page 11
• "Configuration in LABCAR-RTC" on page 12
• "Assigning “Load in Slot x” to Connector “Load n”" on page 13
• "The Load Signals at the Backplane Connectors" on page 14
2.1 Current Sources
The current sources of the ES4435.1 Current Source Load Board are controlled
MOSFET current sources for regulating current – the input operational amplifier
is addressed via a 10-bit D/A converter with a serial input.
Mechanical relays control the pull functionality.
Operation Modes “Pull-Up” and “Pull-Down”
In the operation mode “pull-up”, the current source is switched internally
against the positive potential of the selected battery node. A current flows from
the source when the load is connected to an ECU pin with lower potential (e.g.
-UBatt).
In the operation mode “pull-down”, the current source is switched internally
against the negative potential (-UBatt). A current flows into the source when the
load is connected to an ECU pin with higher potential.
2.1.1 Currents
The maximum power of the current sources is 3 W. For the maximum current
rating of the current sources, this means:
• 150 mA (pull-up/pull-down) with a battery voltage of 6..20 V
• 70 mA with a battery voltage of 20..42 V
• 50 mA with a battery voltage of 42..60 V
with an accuracy of 3 mA.
2.1.2 Switched Battery Voltages
All current sources must refer to switched battery voltages in their pull-up func-
tion, i.e. the corresponding current source only becomes active when the corre-
sponding battery node is activated.
The battery node control signals are TTL signals which are applied from the
ES4408CON.1 Communication Interface to the backplane of the ES4408.1 Load
Chassis.
Note
The ES4435.1 Current Source Load Board can only be operated in connection
with LABCAR-RTC! Otherwise, leakage currents of the MOSFETs can lead to
signal problems as the relevant source is disabled but configured as pull-down.
If the ES4435.1 is disabled in LABCAR-RTC, these problems do not occur.
