ROLLS-ROYCE MARINE AS-BRATTVAAG WRC1021B

ROLLS-ROYCE MARINE AS-BRATTVAAG WRC1021B (PN:63335) is a rugged marine auxiliary machinery control pcb card from Rolls-Royce Bratvaag marine propulsion and automation system. The marine auxiliary machinery control pcb card serves as plug-in rack logic board to govern lube oil pump, seawater cooling pump, valve interlock and auxiliary equipment sequence control. This marine auxiliary machinery control pcb card receives 24VDC field feedback signals and communicates bidirectionally with main propulsion controller rack. The marine auxiliary machinery control pcb card adopts conformal coated PCB and vibration resistant hardware, suitable for installation inside marine engine room switchboards.

This board performs pump & valve safety interlock logic control for marine auxiliary equipment operation. The pump & valve safety interlock logic control verifies permissive preconditions before pump startup to prevent improper activation. The pump & valve safety interlock logic control monitors motor running feedback, overload, phase failure and contact fault signals continuously. The pump & valve safety interlock logic control outputs visual and audible alarm signals to bridge console when abnormal conditions are detected. The pump & valve safety interlock logic control supports manual local operation and remote commands from main automation system.

This ROLLS-ROYCE spare is an essential marine propulsion auxiliary control spare for vessel switchboard overhaul. The marine propulsion auxiliary control spare can replace faulty WRC1021B control boards directly. The marine propulsion auxiliary control spare meets DNV marine classification society safety specifications. The marine propulsion auxiliary control spare is widely fitted on cargo ships, tankers and offshore vessels equipped with Rolls-Royce marine propulsion control system.

ROLLS-ROYCE WRC1021B control PCB is a dedicated plug-in logic board for Bratvaag marine automation rack. It implements start-stop sequence and safety interlock for cooling water pumps and auxiliary valves, collects equipment feedback signals and fault information, exchanges data with main propulsion controller, performing reliably under high temperature, vibration and salt mist marine machinery space environments.
