ENFO IV

Features

The ENFO IV is an engine monitoring device that reads and displays: engine RPM, engine coolant temperature, and engine oil pressure via SAE J1939 CAN messages from the engine Electronic Control Unit (ECU). It also displays vehicle voltage but this is independent of SAE J1939 CAN operation, can be used on both 12 and 24 Volt systems, uses an automatic voltage detection system to determine the low voltage point for alarm activation and it can be connected to an external alarm and external alarm silence switch. High engine temperature (250° F / 120° C), low oil pressure (10 PSI / 70 kPa / 0.70 Bar), or low voltage (11.9V or 23.8V) will cause the ENFO IV to activate the external alarm.
