	Precise Data Acquisition Moxa’s ioPAC 8500 RTUs offer up to 40 kHz-level analog input sampling rate, giving engineers the analog data precision they need to correctly analyze events. In addition, the analog input pre-recording function allows the ioPAC 8500 RTUs to continuously record analog input data before an event trigger point for improved data completeness.
	Sustainable System Reliability The ioPAC 8500 RTU controllers are compliant with EN 50155, EN50121-3-2 and EN 50121-4 standards, which require products to withstand high levels of vibration, and provide surge and ESD protection for the power and communication ports. They also support a wide operating temperature range of -40 to 75°C.
	Easy Data Acquisition Moxa’s ioPAC 8500 RTU controllers come with Moxa’s patented Active OPC server and DA-Center software. Active OPC server adds a non-polling architecture to the standard OPC protocol, giving users the advantage of push-based communication from Moxa’s controllers to the SCADA systems. DA-Center, on the other hand, provides a standard OPC interface that interacts with Moxa Active OPC Server for real-time data collection.
	Easy to Deploy Moxa’s ioPAC 8500 modular RTU controllers support a versatile collection of I/O modules. The compact size and modular design make this ioPAC 8500 ideal for cabinets with limited space, and all of the I/O modules are hot-swappable to allow users to replace the modules without shutting down the system.

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.
