DIN-Rail Computer Extension Module: Fieldbus and Wireless

Extension for Various Applications

The ME4 is a modular extension for embedded applications in transportation, e.g., in trains or wayside. The module adds wireless connectivity and fieldbus and audio functionality to the system CPU. Main applications of the module include predictive maintenance, IoT gateway, diagnostics server, smart vehicle, passenger information and ticketing systems.

Wireless Connectivity

The ME4 comes with one M.2 slot for high speed LTE modems (LTE Advanced or LTE) providing two front-accessible micro-SIM card slots. For GPS/GLONASS functions, the box has an onboard GNSS receiver which can be connected via antenna connector.

Fieldbus and Audio Functionality

The ME4 is equipped with one PCI Express Mini Card slot which is prepared for adding an MVB, CAN bus or audio module. The functions can be made available on two D-Sub connectors at the front panel.

Modular System for Easy Configuration

Due to MEN's modular concept, the ME4 offers flexibility in built-to-order configurations. Via its extension connectors, the box can be easily combined with pre-fabricated CPU modules or other extension modules, for example a PSU or removable storage shuttles, providing additional features and short delivery times.
In the modular system, the data transfer between the modules as well as the power distribution between the individual components takes place via the extension connectors standardized by MEN.

Flexible System Installation

Various mounting options facilitate the integration of the box into an existing environment. The standard 35 mm DIN Rail mounting offers space saving mounting of all system modules on a single rail. Wall mounting and mounting in a 19" rack using adaption brackets are an option.
The aluminum housing with cooling fins allows fanless operation. ME4 has no moving parts, making it maintenance free.

In-Vehicle Qualified and Long-Term Availability

The wireless and fieldbus module is qualified for rolling stock and wayside applications. Long term availability until 2028 minimizes life-cycle management by making the ME4 available at least for this period of time.
