  QTD4 – slow to release delay units

  The TY370/GRP01 is used in safety critical applications where a delay is required between the opening of a control contact and the release of a normally energised slave relay. The slave relay is powered from the TY370/GRP01 and thus does not require a separate supply. The TY372 is used in applications where an operate delay longer than that achievable by slugging is required. Mors Smitt Relays Modular plug in design…

  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…
