DIN-Rail: Modular Gateway Computer for DIN Rail Mounting

The MC50M is a modular gateway computer and part of the DIN rail family from MEN. The box is based on Intel's Atom E3900 series with low power dissipation and scalability in performance and memory. The modular expansion concept makes the DIN rail family a cost-effective and flexible partner.

  • Intel Atom E3900 series
  • Up to 8GB DDR3 SDRAM; M.2 NVMe slot
  • Trusted Platform Module
  • Gb Ethernet, USB 3.0, RS232, RS485/422, DisplayPort
  • DIN rail, wall or 19" rack mounting
  • Input voltage 24 V DC nom. with ignition
  • Full-range PSU 9 V DC to 60 V DC
  • -55°C to +70°C, EN 50155 compliant

Embedded system for IoT, security and predictive maintenance

The MC50M is a modular DIN rail box PC for embedded applications in transportation. The computer platform is based on Intel's Atom E3900 CPU series. This makes the MC50M the ideal basis for functions such as security gateway, predictive maintenance, CCTV, ticketing systems or as a diagnostic server.

Modularity and railway conformity

The MC50M can be used as a stand-alone product or in combination with a range of pre-fabricated extension modules, providing additional features and short delivery times.
Extension modules can provide application-specific functions such as wireless communication (LTE advanced, WLAN, GNSS), MVB, CAN bus or other I/Os. A removable storage shuttle supports the integration of one to two 2.5" SATA hard disks/SSDs. The wide range PSU allows isolated power supply from 24 V DC to 110 V DC nominal and extends the entire system to EN 50155 compliance.

Power-saving design and safety

The board management controller provides increased reliability and reduces downtime. The Trusted Platform Module supports security and encryption features. With the ignition switch for remote startup and shutdown control, the platform provides additional energy saving features.

Robust and future-proof

The aluminum housing with cooling fins ensures conductive cooling and fanless operation. The MC50M has no moving parts, so it can be operated maintenance-free.

The long-term availability of 15 years from product launch minimizes life cycle management by making the MC50M available for at least this period.

DIN Rail: Flexible configuration in a modular system

MEN’s DIN rail concept is designed for flexible configuration of module combinations and is suitable for embedded IoT applications in various markets. The CPU modules can be flexibly combined with various expansion modules and power supplies.

In the modular system, the data transfer between the individual modules as well as the power supply of the components is implemented via the expansion connectors standardized by MEN.

The concept specifications include housing dimensions, mounting, cooling and IP protection. In addition, the expansion connectors and their pin assignment are defined.

DIN rail mounting (35 mm) is standard. Wall and 19'' rack mounting is possible using adaption brackets.
