Sealed engine mounted module for reliable performance Provides switching relays for starter motor solenoid, glow plug, and fuel solenoid Individual automatic fuses for circuit protection LED indicators for circuit status and fault finding Anti-vibration mounts and easy connection via loom plugs; isolates heavy currents for individual circuit protection The Interface Module is a sealed engine mounted module that provided switching relays for the starter motor solenoid, glow plug and fuel solenoid. Each of these circuits is protected with individual automatic fuses mounted in the module. Individual LED's illuminate when each circuit is energized in addition these LED's greatly aid when fault finding. This module is mounted on the engine with anti-vibration mounts and is easily connected to the engine via loom plugs. Use of the EIM 630-466 PLUS means that heavy currents such as fuel solenoid power are isolated from the control panel thus enabling individual protection of each of the circuits.
