12V Engine Interface Module for Generators, Centralized Relay Control and Overspeed Protection

Engine Interface Module — EIM Plus (Model EIM PLUS, Type 859767) A sealed, enginemounted control module that provides reliable switching for key engine circuits. The module supports Starter Motor Solenoid, Glow Plug, and Fuel Solenoid control, with each circuit individually fused and protected. LED indicators give clear visual confirmation whenever a circuit is activated. Key benefits Simplifies engine wiring and control by centralizing relay switching for starter, glow plug, and fuel solenoid circuits. Protects individual circuits with dedicated fuses, reducing downtime from blown circuits and simplifying troubleshooting. Provides immediate visual feedback via LED indicators, helping technicians confirm circuit operation at a glance. Flexible application options with two versions to match existing control panels and safety functionality. Sealed, enginemounted design for dependable operation in engine environments; designed for robust performance on 12V DC systems. Core features Functions: switching relays for Starter Motor Solenoid, Glow Plug, and Fuel Solenoid. Circuit protection: each circuit is individually fused and protected. Visual feedback: LED indicators for each circuit activation. Versions: EIM Basic for control panels that already include overspeed shutdown; EIM Plus for panels without overspeed shutdown. Overspeed protection (EIM Plus only): monitors engine speed and triggers an Overspeed Fault if speed exceeds the adjustable set point. Overspeed Set Point is adjustable for both 50 Hz and 60 Hz generator sets. Power: 12V DC operation. Condition and identification: 100 percent , Model EIM PLUS, Type 859767. Construction: sealed enclosure designed for enginemounted installation. Typical applications Generator sets: Integrate the EIM Plus into generator engine installations where central relay switching and overspeed monitoring are required for 50 Hz or 60 Hz sets. Control panel retrofits: Use EIM Basic when the existing control panel provides overspeed shutdown, or EIM Plus when overspeed protection must be added at the engine level. Field service and maintenance: or upgrade engine relay modules to restore reliable starter, glow plug, and fuel solenoid control while adding clear LED status indicators for faster diagnostics. Why choose this module Matches common 12V DC engine electrical systems and works with panels that do or do not include overspeed shutdown by selecting the appropriate version. Reduces wiring complexity and improves protection and visibility of critical engine circuits. Adjustable overspeed set point on the EIM Plus makes it adaptable to both 50 Hz and 60 Hz generator configurations. Technical summary Model: EIM PLUS Type: 859767 Voltage: 12V DC Condition: 100 percent Mounting: enginemounted, sealed enclosure Compatible versions: EIM Basic and EIM Plus for different control panel arrangements For installations that require dependable relay switching, circuit protection, and clear operational feedback, this Engine Interface Module offers a practical, enginemounted solution with the option to add overspeed protection when needed.
