Murphy 2-1/16 in. A-20 Type Black Display and Diagnostic Module 8-32V Deutsch Connector - MDDM20-B-A

The Murphy Display and Diagnostic Module MDDM20-B-A is best viewed either straight on or at 6 o’clock position. The MDDM is a powerful, easy to use multifunction tool that enables the operator to view many different engine parameters and engine service codes. The MDDM includes a two line by eight character backlit LCD display. The top line displays data labels, i.e. "EngHrs". The bottom line displays appropriate units information i.e "80 psi" for oil pressure. The UP and DOWN push buttons located on the front of the MDDM, are used for scrolling through the parameters and viewing the menu list. Two LEDs (amber and red) are used to annunciate active fault messages received by the MDDM. Other components in the system are microprocessor-based analog gauges for displaying critical engine data broadcast by the ECM: engine RPM, oil pressure, coolant temperature, system voltage, etc., a combination audible alarm and relay unit for warning and shutdown annunciation. Up to 32 components may be linked to the MDDM by an RS485 daisy chained twisted pair cable up to 1,000 meters from the MDDM. The MDDM and all connected components can be powered by 12 or 24 volt systems, are back lit using LEDs, and are 100% environmentally sealed.
