Murphy Mark IV Digital Fault Annunciator Tattletale

The Murphy Mark IV Digital Fault Annunciator Tattletale is a device designed to monitor and alert users of potential faults or issues within a system. It features:

  • 15 sensor inputs: These inputs can be connected to various sensors to monitor parameters such as temperature, pressure, or flow.
  • Timed start-up: The device allows for timed start-up of connected sensors to ensure proper system initialization.
  • Manual stop: A dedicated sensor input (number 47) can be used to manually stop the system.
  • Overspeed protection: Sensor input number 46 can be connected to an overspeed switch (tachometer) to monitor and protect against excessive speeds.
