RX371 Ruggedized Controller
The RX371 is the most rugged OCS Horner has ever manufactured and is designed for harsh environment use, with its cast aluminum and steel chassis, ruggedized heavy duty function keys and
impact resistant Lexan® touch screen. Snap-on I/O is provided by up to four metal SmartStack® units directly on the back. SmartStix® expansion I/O is also supported.
The RX371 features a bright new 5.7” QVGA, TFT screen with over 32K colors. The screen is bright with a 700 NIT brightness rating. RX371 is fast and has a typical logic scan rate of 0.2mS/K. RX371 has advanced control capabilities including floating point, multiple
autotuning PID loops and string handling capabilities. In addition, the RX371 features embedded Ethernet and supports many Internet capabilities such as remote data access, programming, hosting HTML-based web pages, and FTP file transfer. Plus, it has a built-in MicroSD®
memory slot that allows users to easily store machine or process data and screen captures (up to 2GB). Programs can be updated and loaded through MicroSD®…a real advantage for OEMs or those supporting distant sites.
The RX371 Color Touch OCS has optional I/O features, too. The base RX371 unit provides control, operator interface, and communication functionality while the optional metal SmartStack® or remote SmartStix® units provide I/O
connectivity. A USB Mini B connector allows easy connection to your PC for programming and interface design. A USB A connector supports data exchange with standard USB flash drives.
Ruggedized features for harsh enviroments and rigorous use
The RX371 is unique as it has been optimized for enhanced temperature, environmental, shock and vibration protection. Circuit boards are conformally
coated, adding a layer of protection. Plus, the touch screen is constructed of Lexan® and is impact resistant. All function keys have been designed for 30 Million + operations with outstanding tactile feel. Finally, the RX371 incorporates a metal chassis designed for
rigorous use.
