The BoltGATE 20-25 is EN50155 certified and is designed to exceed the requirements of rolling stock in the Tx temperature class. With IP65 rating, it is extremely rugged and suitable for any application where consistent performance and reliability are a must.

Based on the Intel Atom E38xx processor family, with up to 4GB of RAM and 8GB of eMMC, the BoltGATE 20-25 offers extra storage expansions through optional internal or removable 2.5″ SATA SSD/HDD, mSATA, and a user- accessible microSD slot.

At 30W max, the BoltGATE 20-25 is a fanless, compact unit that provides a large number of communication and I/O interfaces: two Gbit Ethernet, protected USB (one USB 2.0 for general purpose and one USB 2.0 for maintenance), four opto-isolated serial (RS-232/RS485/RS-422) interfaces, eight opto-isolated DIO plus odometer and key signals, audio line in/ out and video. It also features a wide range of connectivity capabilities including a global cellular modem, Wi-Fi, Bluetooth Low Energy, and a dedicated internal GPS with Dead Reckoning.

As a result of its modular design, the BoltGATE 20-25 can easily be customized for the requirements of the target application. With three full miniPCIe slots, it can accommodate additional connectivity or communication options and, through Eurotech Professional Services, it can offer custom front panel configuration and connectors or customized software images.

The BoltGATE 20-25 comes with Linux and Windows operating systems. It also includes a genuine Oracle Java SE Embedded 8 Virtual Machine and Everyware Software Framework (ESF), a commercial, enterprise-ready edition of Eclipse Kura, the open source Java/OSGi middleware for IoT gateways. Distributed and supported by Eurotech, ESF adds advanced security, diagnostics, provisioning, remote access and full integration with Everyware Cloud (EC), Eurotech’s IoT integration platform (separately available).
