Preconfigured Central Controller
The freely programmable electronic control unit ESX is an independent measurement and control device for the sensor-actuator management. Multiple independent or linked tasks can be processed in real-time..
Flexibility / scalability
Due to the extension possibilities via 2 internal interfaces, the control unit covers a wide range of applications for your machine. I/O and interface extensions are available.
It is also possible to realize customer-specific, interference-free expansion boards quickly and without affecting with the actual certification of the control unit.
A robust aluminium die cast housing (Protection IP65, opt. IP67, with GORE-TEX membrane for pressure compensation) provides both, a high level of protection against electromagnetic interferences as well as reliable protection against mechanical stress.
The ESX was developed especially for use in vehicles and machines, which have to function reliably in harsh ambient conditions and extreme operating temperatures of -40 … +85°C (-40 … 185°F).
The ESX was developed and has been approved by the TÜV (German Technical Inspectorate) for applications in safety-critical applications up to SIL2 in accordance with IEC 61508. A second switch-off path via a safety relay is available for the digital /PWM outputs.
Diagnosis and error handling
All inputs and outputs are protected against overvoltage and short-circuits and are diagnosable.
