  • Smart Relay Monitoring System

    Railcar builders have been using relays to control equipment for years. During train maintenance, relays and devices such as lamps, door push-buttons or else are often exchanged before their end of life or when they are no longer working. Moving from schedule-based to condition-based maintenance saves significant maintenance costs for train operators. Mors Smitt™ smart Relay Monitoring System is developed to analyze the condition of relays and connected devices in real-time…
