Addressing the Challenges Faced by OEMs -
New trends resulting from the diversification currently occurring in powertrains place demands on measurement systems that conventional devices simply cannot fulfil. The future technologies used in data logging devices must provide extended measurement ranges combined with precise data logging capability and high throughput rates over a very wide spectrum of temperatures.
AVL FEM 4 represents the next generation of IO measurement systems.

Direct measurement of voltages |
Highest measurement accuracy |
Wide operating temperature range |
Adaptive modular design |
High sampling and data throughput rates in real-time |
By using modern signal conditioning and the real-time EtherCAT interface, the FEM 4 meets the demands of modern development processes. The new circuit concept enables you to control and measure signals such as currents, temperatures, frequencies and voltages directly up to 2,400 VDC without influencing the measurement signal. The measuring modules in a FEM 4 can be quickly adapted to new tasks, helping you to increase flexibility and ultimately optimize the utilization of your test facilities.

The following benefits are essential in order to measure all data relevant for the characterization of a unit-under-test and support the continuous increase of testing efficiency:
Adaptive Modular Design
Easy and rapid connection to all kinds of powertrain technologies thanks to a cascading mechanism and frontend design.
Distributed, Resilient System
The wide temperature resilience and the distributed design of the modules enable installation in close proximity to the unit-under-test.
Highest Measurement Accuracy
Calibrated according to ISO 17025 – fewer iterations, reduced costs and increased efficiency.
Galvanic Isolation
High galvanic isolation up to 1,500 VDC for electrified modules support a direct measurement of DC voltages up to 2,400 VDC without influencing the measurement.
Advanced Data Communication
High sampling and data communication in real-time, e.g. EtherCAT.
High Voltage Isolation
These modules offer a high degree of insulation of the individual connector (single channel or group of channels) for use at high voltage potentials, e.g. in electrification.
Voltage Measurement Modules
The voltage modules enable measurements at low and high voltage (HV) levels with up to 8 selectable measurement ranges depending on the module type.
Current Measurement Modules
The current measurement modules enable measurements up to ±24 mA, or up to 2,000 A with an additional ballast.
Temperature Modules
The following modules are suitable for temperature measurements. Depending on the type, the channels are individually isolated or combined into groups.
Universal Modules
In order to cover the widest possible range of applications, the following universal modules are available.
Active Modules
In addition to passive measuring modules, the FEM 4 product family also offers active control modules for signal generation.
Basis and Extension Modules
Further basic and extension modules are offered to complete the portfolio.
