Compact, Anti-Vibration Design 
The ioPAC 8020--a rugged modular programmable controller with 5 or 9 I/O slots--supports a wide selection of I/O modules and comes with a DIN rail mount specifically designed to withstand severe vibrations. This RTU features an aluminum chassis for vandal protection, spring-type terminal blocks for gas-tight and vibration resistant wire contacts, and optional M12 connectors to ensure that your Ethernet connectors remain connected at all times.


Innovative C/C++ Programming with Timesaving I/O Access and Control

The ioPAC 8020-C further features a Linux/GNU platform adapted to data acquisition and condition monitoring. The main advantage of this open C platform is its user-friendly SDK, which helps economize on installation and configuration overhead by reducing your programming workload for key areas like I/O control and condition monitoring, SCADA/DB interoperability, and improving smart communication controls.




Seamless Data Transmissions with Ethernet by-pass Function

The ioPAC RTU controllers have a built-in Ethernet switch with 2 ports for cascading multiple ioPAC RTU controllers in a convenient daisy-chainin configuration. Together with a poweroff bypass mechanism, the ioPAC RTU controllers can maintain continuous, seamless data transmissions even when one of the RTUs fails.





Fast Track Integration for Wayside Condition Monitoring and Preventive Maintenace

This white paper will discuss how railway operators are adopting increasingly sophisticated condition-based maintenance regimes to control costs and improve track performance, some of the key difficulties system integrators need to overcome when deploying wayside condition monitoring systems for railway preventive maintenance, and how using a single condition monitoring platform can save time and costs for deployment and maintenance.


Railway Preventive Maintenance Solutions Flyer


See how Moxa's ioPAC 8500 RTU controllers make railway preventive maintenance easy. The RTUs provide extremely accurate data, giving engineers the information they need to identify anomalous conditions, before failures occur. The ioPAC 8500 RTUs are also designed to work reliably in harsh environments, and modules can be easily replaced to shorten system downtime.
