Moxa’s RNAS-1200 network-attached storage (NAS) units provide high performance, high reliability, and high capacity data storage in harsh industrial environments. All RNAS-1200 devices are housed in a fanless, thermally efficient, dust and water-protected IP54-rated chassis. This sealed enclosure eliminates internal fans as a point of critical system failure, and protects the internal components from dust and water splashes. RNAS-1200 devices are compliant with mandatory sections of EN 50155, covering operating temperature, power input voltage, surge, ESD, and vibration, as well as conformal coating and power insulation, making them suitable for a variety of industrial applications.
RNAS-1200 devices also come with Moxa’s Intelligent Heating Solution™ (IHS) and Data XPro™ technologies. IHS automatically heats the system to ensure reliable operation even in extremely low temperatures, while the Data XPro™ utility provides intelligent data and drive protections against extreme heat and vibration. In addition, the series’ remarkably fast array synchronizations make the full data and hardware redundancies of RAID 1 a feasible alternative for industrial applications, while the two gigabit PoE+ network interfaces provide not only network redundancy, but also a highly efficient, fully redundant power supply over the same set of wires.
The RNAS-1200 Series combines simple configuration and multiple data and hardware redundancies in a compact, durable, fanless chassis ideal for industrial environments where extreme temperatures and vibration are a concern. The RNAS-1200 NAS devices are your best choice for industrial-strength data storage for rolling stock video surveillance or remote site data storage applications.

White Paper:
Illustrating the Technology Behind Industrial-Grade NAS

Network-attached storage (NAS) appliances have gained a firm foothold in consumer markets, and have long dominated in enterprise-scale networks. Now, NAS is gaining further ground in the industrial world, particularly in transportation solutions, but also in other harsh environments like wind farms, electrical substations, or other remote installations. In this paper, learn about what challenges a NAS device engineered for industrial-grade purposes must overcome, and how technology is developing to overcome trials such as extreme temperatures of both cold and heat, high vibration, sudden shocks, network and power redundancy, resource conservation, and data security.

Railway Data Security: Building a Durable NVR Platform

In this white paper, Moxa identifies a few solutions to the key challenges railway operators face when trying to secure their data and devices against the peculiar tests of the railway environment. Taking network video recording devices as the stepping off point, we give a brief analysis of how a train’s vibrations, extreme temperature fluctuations, and power supply can adversely affect device functioning and durability. The paper then goes on to consider how thoughtful engineering can eliminate these factors as a point of concern, while at the same time building strong value for the customer through carefully considered, centralized, and automated controls and failsafes.

Engineering One Computing Platform for All Classes
of Train

This whitepaper discusses the various applications and subsystems to which an on-board train computer may be applied, outside of signaling and control. Most talk within the train industry focuses the vital signaling and control automation; however, today’s trains and other forms of mass transit have many more demands beyond these critical systems. Each class of train has specific requirements and needs that are defined by its on-board auxiliary automation systems. While these requirements vary according to the train environment being served, a core set of hardware requirements may be met that will allow a single, extensible computer to serve in virtually any on-board auxiliary role required. This white paper examines what these core requirements are, and shows how careful computer engineering can cut deployment and integration times for engineers tasked with building on-board train systems.
