The MurphyLinkTM gages are a series of instruments designed to display information transmitted by the Murphy Display and Diagnostic Module (MDDM) in a traditional analog format. Communication from the MDDM to these units is via an RS485 twisted pair proprietary serial link.


The MurphyLinkTM components are environmentally sealed, LED back lit (green) and are available in a standard 2 inches diameter, plastic case, MLA20 Series, (metal case for the audible alarm MLAA20 models). The MLA35 Series Tachometer or Speedometer have a 3-3/8 inches in diameter, plastic case.


The MurphyLinkTM gages can be powered by 12 or 24 VDC systems. For 24 VDC systems an MLVC2412 voltage regulator is required for back light power supply.
