Introduction

Moxa’s 85M series modules can be installed in both ioPAC 8500 and ioPAC 8600 systems. Modules are available with DI/Os, AIs, Fast AIs, and serial interfaces, giving users a wide choice of options to choose from. Enough options are available to allow users to select the best I/O combination for their target application. All 85M modules are designed for railway industry applications, and as such are compliant with EN 50121-3-2, EN 50121-4, and EN 50155. In addition, the modules support a wide operating temperature range of -40 to 75°C.

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.
