ehb SMARTmodul 04 flex

ehb SMARTmodul 04 flex


The ehb SMARTmodul 04 flex delivers a multitude of functions for

monitoring and controlling applications via CAN bus (SAE J1939).

Analogue, digital and CAN bus signals are reliably interconnected and evaluated

Simple networking of a multitude of sensors, actuators and units.

Inputs and outputs can be controlled via CAN bus
Control tasks are easily achieved via the connected HMI without programming efforts at the controller.

Individually programmable via CAN

The inputs and outputs can be configured via CAN messages.

UV-resistant, rugged PA6 housing for screwed installation

Connection via standard plug connectors.

Fast installation and retrofit. Dependable functioning in industrial environments.

No direct access to the sensors installed at the engine

The engine warranty is not affected.
