Marine Control Board
JRCS / Japan marine control equipment
New product
The JRCS LCU-M01B-1 PCB Card is a marine electronic control board used within JRCS shipboard automation and control systems.
The supplied board photographs clearly show the PCB marking LCU-M01B-1, along with an onboard PP15-24-5 DC-DC power module, processor/memory devices, relays, fuse protection and a large multi-pin backplane connector.
Related JRCS market listings confirm that the same LCU family includes several search variants such as LCU-M01A-22, LCU-M01A-22II, LCU-M01A-32, LCU-M01B and LCU-M01B-22C. These part variations are important when searching for obsolete or replacement marine control boards.

The JRCS LCU family appears in several model and revision formats, and buyers often search by only a partial marking.
Examples currently found in marine spare-parts listings include:
LCU-M01A-22 – listed as a JRCS / Japan Radio Electric PCB card.
LCU-M01A-22II – listed as a JRCS PCB with model LCU-M01A.
LCU-M01A-32 – repeatedly indexed as a JRCS PCB card / control board.
LCU-M01B – market listings identify PCB marking LCU01B-1.
LCU-M01B-22C – another documented LCU-M01B revision, also marked LCU01B-1.
For SEO and replacement sourcing, this is why LCU-M01B-1 / LCU-M01B / LCU01B-1 and related LCU-M01A variants should all be included naturally on the same technical page.
The board construction visible in the supplied images includes:
The exact function of each terminal and IC depends on the specific JRCS system and board revision, so schematic functions should not be assumed without the correct JRCS manual.
Broader JRCS inventory pages and marine-electronics listings show related LCU models such as:
LCU-M02A
LCU-M100A / LCU-M100A-1
LCU-M110B
LCU-M400A
LCU-M400B
LCU-TM15-L / LCU-TM15-R
LCU-TM42-L / LCU-TM42-R
LCU-TMCOM-L
LCU-TMDI-L / LCU-TMDI-R
LCU-TMTEMP-L / LCU-TMTEMP-R
These are related JRCS LCU-family boards, not guaranteed direct replacements for LCU-M01B-1. Exact PCB marking, revision, system configuration and connector arrangement must be matched before replacement.
JRCS LCU boards may be found in shipboard automation and control installations involving:
Engine Room Automation • Alarm Monitoring • Machinery Control • Generator Control • Local Control Panels • Switchboard Automation • Monitoring Systems • Remote I/O • Ship Control Systems
Typical vessels include:
Bulk Carriers • Container Ships • Tankers • Chemical Tankers • LNG/LPG Carriers • General Cargo Ships • Offshore Vessels • Ferries • Passenger Vessels • Tugboats
The exact application of a specific LCU card depends on the original JRCS system configuration.
Check:
Inspect:
Check the relay, driver circuitry, output transistor/IC, supply voltage and the actual command from the control system.
Older marine PCBs can develop faults from:
Vibration • Heat • Humidity • Corrosion • Aged capacitors • Relay contact wear • Connector oxidation • Dry solder joints
Do not assume that every visually similar LCU card is interchangeable. Revision, programmed memory, DIP/rotary settings and vessel-specific system configuration may differ.
Before replacing a JRCS LCU PCB, record:
Full PCB Marking • Revision • EPROM Label • Switch Settings • Connector Arrangement • Vessel/System Name • Fault Symptoms
If a replacement is visually similar but has a different suffix such as -22, -22II, -32, -22C or M01B, compatibility should be verified first.
This is particularly important with legacy marine automation boards where the PCB hardware may look almost identical but programmed firmware or I/O configuration can be different.

Many ships continue to operate original JRCS automation systems for years after the original equipment becomes difficult to source.
Replacing one failed PCB can often avoid unnecessary modification of the complete:
Control Panel • Wiring • Sensors • Alarm System • I/O Network • Generator Controls • Engine-Room Automation
For this reason, buyers frequently search not only by product name but by exact markings such as:
LCU-M01A-22 • LCU-M01A-32 • LCU-M01B • LCU01B-1
This is why part-number-based SEO is especially valuable for older marine electronics.
It is a JRCS LCU-series marine control PCB. The supplied board is physically marked LCU-M01B-1.
Market listings for LCU-M01B show boards carrying the marking LCU01B-1, but replacement compatibility should still be verified by complete board revision and system details.
No. They are separate model/revision designations in the same general JRCS LCU family and should not automatically be considered interchangeable.
This model is documented in marine spare-parts listings as JRCS LCU-M01B-22C PCB Card, with LCU01B-1 marking.
Often yes, depending on the failure. Power supplies, capacitors, relays, connectors and some discrete components can sometimes be repaired, but processor or programmed-memory failures may require a donor or replacement board.
Yes. Other LCU and JRCS marine automation boards can be sourced subject to exact model and stock availability.
