The MurphyLink 250F Coolant Temperature Gage 2 in. with Amp Mini Universal Connector and A-20 Type Black Bezel MLA20-B-250-AA is 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 MurphyLink components are environmentally sealed, LED back lit (green) and it has a 2 inch (51 mm) diameter, plastic case.

The MurphyLink MLA20-B-250-AA gage can be powered by 12 or 24 VDC systems.  For 24 VDC systems an MLVC2412 voltage regulator is required for back light power supply.
