Integrated Central Controller

The freely programmable control unit ESX-C is a compact variant of the ESX from the 16-bit control unit family.

Flexibility / scalability

The controller is currently available in 3 configuration variants. The internal interfaces for the extension with expansion boards are not available for this control unit.

Ambient conditions
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 interference as well as reliable protection against mechanical stress.
The ESX-C 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).

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.
