JRCS SGD-M100A-F-1B MAIN-BOARD PCB（PN:D051052）

JRCS SGD-M100A-F-1B is a rugged main processor motherboard PCB for JRCS SMS-22 marine graphic annunciator / monitoring panel system. The graphic terminal main board is the core CPU card for bridge mimic display and common alarm processing unit. This main board PCB integrates CPU, program memory, data RAM, serial communication interface and display driver circuit. The main board PCB adopts conformal coated circuit board, resisting salt mist, heavy vibration and electromagnetic interference inside marine wheelhouse environments.

This board delivers graphic display driving & alarm event processing logic control. The graphic display driving & alarm event processing logic control communicates with rack I/O cards via serial bus and receives pump/valve dry contact alarm signals. The graphic display driving & alarm event processing logic control drives mimic graphic panel to show real-time auxiliary machinery status. The graphic display driving & alarm event processing logic control processes alarm acknowledge, reset and stores fault timestamp history. The graphic display driving & alarm event processing logic control supports built-in hardware self-diagnosis for troubleshooting.

This JRCS spare is an essential marine graphic annunciator main CPU spare for bridge mimic panel overhaul. The marine graphic annunciator main CPU spare can replace faulty SGD-M100A-F-1B mainboard PCB directly. The marine graphic annunciator main CPU spare meets DNV marine classification society safety specifications. The marine graphic annunciator main CPU spare is widely fitted on cargo ships, tankers and offshore supply vessels equipped with JRCS SMS-22 alarm & mimic display system.

JRCS SGD-M100A-F-1B mainboard is the core controller of JRCS SMS-22 marine graphic mimic panel. It handles field alarm data processing, mimic graphic display driving and system self-check, performing reliably under high humidity and salt spray marine wheelhouse environments.
