Introduction
1.1.3
Control Unit
The ES4408.1 Load Chassis has one further slot on the rear for the optional
ES4408CON.1 Communication Interface for the following functions:
• Master controller for all boards in the ES4408.1 Load Chassis
• Ethernet interface
– for communication with LABCAR-RTPC (and also with LABCAR-OPER-
ATOR)
or
– for controlling the ES4408.1 Load Chassis with SCPI commands
For more details, refer to the ES4408CON.1 Communication Interface User’s

1.1.4
The System Components
In addition to the ES4408.1 Load Chassis and the optional ES4408CON.1 Com-
munication Interface, the following boards are also available for the load system:
• ES4434.1 Configurable Load Board
The ES4434.1 is a manually configurable board with 24 channels for pull-
up/pull-down loads (equipped with 24 510
Ω
/3 W resistors).
• ES4435.1 Current Source Load Board
The ES4435.1 is a board with 24 current sources up to 150 mA which can
be controlled using software
• ES4455.1 Load Board
The ES4455.1 is a carrier board with four channels for piggybacks with
ohmic, capacitive and inductive loads to 90 V and to 20 A (with battery
voltage).
The following piggybacks are currently available
– PB4451CR Piggyback for 2 RB CRS Injectors
– PB4451GDI Piggyback for 2 RB GDI Injectors
The ES4455.1 Load Board can also be supplied as an assembled version
with these modules:
– ES4450.2 Load Board for 4 RB CRS Injectors
The ES4450.2 enables the simulation of four injectors of the Bosch
Common Rail System (CRS). It consists of the ES4455.1 Load Board
and two piggybacks of the type “PB4451CR Piggyback for 2 RB CRS
Injectors”.
– ES4451.3 Load Board for 4 RB GDI Injectors
The ES4451.3 enables the simulation of four injectors of the Bosch
gasoline direct injection system. It consists of the ES4455.1 Load Board
and two piggybacks of the type “PB4451GDI Piggyback for 2 RB GDI
Injectors”.
The relevant User’s Guides contain detailed descriptions of the individual compo-
nents.
