The modular ES4408 Load Module provides electrical loads to electronic control units (ECUs) under test on a Hardware-in-the-Loop (HiL) system. It offers a high number of pull-up and pull-down loads, as well as simulated solenoid-valve-controlled fuel injectors.
Functions at a Glance
- Integrable with all commonly used HiL test systems
- Modular construction provides flexibility in selection of loads
- Provides a wide variety of electrical loads up to 60 V DC or 20 A
- Loads can be calibrated
Modular Construction
The ES4408 is a 19-inch rack mount system which can accommodate up to 12 load boards. It provides an Ethernet communication interface ES4408CON through which the user can control the load configuration. The internal controller monitors all internal functions and facilitates scanning of control signals and parameters. The ES4408 comes with a universal power supply (100 V to 250 V).
The following selection of load boards is available:
- ES4434 Configurable Load Boad (24-CH)
- ES4435 Current Source Load Board (24-CH)
- ES4450 Load Board for 4 RB CRS Injectors
- ES4451 Load Board for 4 RB GDI Injectors
- ES4455 Load Board (4-CH)
