The Murphy Display Head TTD-H displays operational and configuration data. Configuration parameters are entered via keypad or download from MConfig software. The operator interface will accept digital inputs directly on the back of the unit. Power is provided to the Display Head via a direct Phoenix connector or a cable connecting to a remote mounted power supply. The display head contains the microprocessor, the Liquid Crystal Display (LCD), the membrane keys for configuring the sensors inputs and the sensor input terminal blocks.

The TTD liquid crystal display annunciates any fault from the sensor inputs, displays engine speed, and elapsed time. Other features for the TTD model are: built-in Test Mode to test the sensor circuits without shutting down, Pre-lubrication and Post-lubrication timers, and onboard backup battery to retain the fault display after shutdown on ignition powered units.
