HYUNDAI ELECTRICAL HEEM-2 MSU-111C MOTOR AUTO CONTROL UNIT

This HYUNDAI ELECTRICAL HEEM‑2 MSU‑111C is a timer & sequential control unit for Hyundai HEEM‑2 marine generator and motor automation system. The motor auto control unit provides adjustable timing functions including parallel running timer (0.5~25 sec), pressure build-up timer (0.5~25 sec) and sequential start timer (0~100 sec) for marine auxiliary genset and pump motor sequence control. The motor auto control unit executes motor start/stop sequence logic, interlock supervision and time delay regulation for automatic motor operation. The motor auto control unit receives feedback signals from pressure switches and motor status contacts, and outputs relay signals to control contactors and safety interlock circuits. The motor auto control unit adopts compact rack plug-in design and marine grade circuit components to withstand engine room vibration and temperature fluctuation.

This unit governs sequential motor startup and timing interlock for marine auxiliary machinery. The HEEM-2 MSU-111C timing module has front panel LED indicators for power status, timer running and fault alarm on-site inspection. The HEEM-2 MSU-111C timing module supports adjustable timer setting via potentiometers on the module front side. The HEEM-2 MSU-111C timing module meets marine classification requirements for seagoing vessel engine room MCCB control cabinets. The HEEM-2 MSU-111C timing module is widely used on bulk carriers, tankers and cargo vessels equipped with Hyundai HEEM-2 marine automation system.

It serves as a critical spare timing control component for marine auxiliary motor automation system overhaul and retrofit. The Hyundai HEEM-2 MSU-111C control unit is manufactured to original factory specifications for direct replacement. The Hyundai HEEM-2 MSU-111C control unit ensures stable sequential motor startup and safety interlock protection and reduces vessel downtime during maintenance work. The Hyundai HEEM-2 MSU-111C control unit supports simple wiring and fast on-site timer parameter adjustment and function verification. The Hyundai HEEM-2 MSU-111C control unit is stocked by global marine genset automation spare parts suppliers worldwide.
