EF2MPU1.1 Printed Circuit Board

EF2MPU1.1 is a rugged main processor unit PCB card for marine engine room monitoring and alarm rack system, Eurocard plug-in cassette form factor. The MPU main control board acts as the rack master controller, integrates CPU, flash memory, RAM and internal rack bus interface. This MPU main control board runs core system program, executes data processing and communication management for all slave I/O cards. The MPU main control board adopts conformal coated PCB construction, resisting salt mist, heavy vibration and electromagnetic interference inside marine machinery spaces.

This board delivers system program operation, process data calculation & rack internal bus master communication logic control. The system program operation, process data calculation & rack internal bus master communication logic control receives analog and discrete field signals from input acquisition cards. The system program operation, process data calculation & rack internal bus master communication logic control judges alarm conditions and records timestamped fault event logs. The system program operation, process data calculation & rack internal bus master communication logic control sends alarm and control commands to output modules and bridge HMI panels. The system program operation, process data calculation & rack internal bus master communication logic control continuously performs hardware self-diagnosis and detects communication failures of slave I/O cards.

This spare is an essential marine automation main CPU spare for alarm rack overhaul. The marine automation main CPU spare can replace faulty EF2MPU1.1 PCB cards directly. The marine automation main CPU spare meets DNV marine classification society safety specifications. The marine automation main CPU spare is widely fitted on cargo ships, tankers and offshore supply vessels equipped with legacy Eurocard marine monitoring rack.

EF2MPU1.1 MPU PCB is classic rack-based main control cassette. It handles overall system monitoring, alarm logic judgment and internal bus data exchange, performing reliably under high humidity and salt spray marine machinery room environments.
