ETAS ES4455.2 - Properties of the ES4455.2 Load Carrier Board and Its Variants ES4450.3, ES4451.4, ES4452.1, ES4453.1, ES4457.1 and ES4458.1 Mounted with Load Modules

ES4455.2 Load Carrier Board - User’s Guide6
Introduction ETAS
The ES4408.1 Load Chassis features three slots of width 14 HP to accept the
ES4455.2 Load Carrier Board and the variants listed above. Fully mounted, it
enables the simulation of 12 injection loads.
In the same way, it is possible to install the ES4455.2 Load Carrier Board and its
mounted variants in the ES5300.1-A Housing and the ES5300.1-B Housing by
means of the ES5372.1 Carrier for ES4455 Load Boards.
In the ES5300.1-A Housing and the ES5300.1-B Housing, it is possible to install
5 boards of width 14 HP. Fully mounted, it enables the simulation of 20 injection
loads per housing.
1.1.1 Properties of the ES4455.2 Load Carrier Board and its Variants ES4450.3,
ES4451.4, ES4452.1, ES4453.1, ES4457.1 and ES4458.1 Mounted with Load
Modules
• 3 U/14 HP add-on card for a LABCAR HiL system.
• Compatibility with the ES4408.1 Load Chassis and, with the use of
adapter card ES5372.1 Carrier for ES4455 Load Boards, also with the
ES5300.1-A Housing and the ES5300.1-B Housing
• Four load inputs for connecting four simulated injection loads to an ECU
• Current measurement for four loads via four galvanically isolated
channels
• Voltage measurement for four loads via four galvanically isolated
channels
• Analog output Online_Probe for current or voltage measurement at one
selectable load
• On-board analysis of load current and load voltage
• Four digital outputs I_Dig_Out_1...I_Dig_Out_4 for outputting the injec-
tion time for each load. Based on the load response, the opening and
closing time of the respective load is also being output
• The signals I_Dig_Out_1, ... I_Dig_Out_4 can be connected to a LABCAR
HiL system.
The variants have the following additional properties:
ES4455.2 Load Carrier Board
• Slot for 4 loads
ES4450.3 Load Carrier Board for 4 RB CRS Injectors
• Simulation for four injectors of the Bosch Common Rail System.
ES4451.4 Load Carrier Board for 4 RB GDI Injectors
• Simulation for injectors of the Bosch HDEV5 gasoline direct injection
ES4452.1 Load Carrier Board for 4 RB GDI Injectors, CVO
• Simulation for injectors of the Bosch HDEV5 gasoline direct injection
• Additional supported functions of the motor ECU:
