ME1 - DIN-Rail Computer Extension Module: Wireless Communication

Extension for Various Applications

The ME1 is a modular extension for embedded applications in transportation, e.g., in trains or wayside. The module adds wireless connectivity 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 ME1 comes with two M.2 slots for high speed LTE modems (LTE Advanced or LTE). For each M.2 slot, two front-accessible micro-SIM card slots are available. The PCI Express Mini Card slot is prepared for adding a WLAN module. For GPS/GLONASS functions, the box has an onboard GNSS receiver and an SMA antenna connector.

Modular System for Easy Configuration

Due to duagon's modular concept, the ME1 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 duagon.

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. ME1 has no moving parts, making it maintenance free.

Rolling Stock Qualified and Long-Term Availability

The wireless communication module is qualified for rolling stock and wayside applications as well as for industrial automation applications. Long term availability until 2027 minimizes life-cycle management by making the ME1 available at least for this period of time.
