Consilium Salwico IOK-4 PCB Card 051010

Consilium Salwico IOK-4 PCB Card 051010 REV – R1E (SLE 9904 636)

The Consilium Salwico IOK-4 (Part Number: 051010, Revision: R1E, SLE 9904 636) is an Input/Output (I/O) control interface board engineered specifically for marine life-safety automation. Deployed as a core subsystem component within the legendary Salwico CS3000 and CS3004 addressable marine fire detection systems, the IOK-4 provides signal bridging between central processor units, internal communication buses, field notification appliances, power supply monitoring circuits, and external relay trips.

The IOK-4 PCB integrates transient voltage suppression, hardware fuse supervision, and opto-isolated I/O channels. Whether replacing a board that has failed due to an onboard 24 VDC ground loop fault or stocking critical Class-mandated safety spares before an annual survey, this PCB maintains factory-calibrated detection and alarm integrity.

Technical Specifications

Features

1. Supervised Marine-Grade Outputs: Drives alarm sounders, bells, optical beacons, and magnetic fire door release mechanisms with integrated open-circuit and short-circuit line supervision.
2. On-Board Fuse Protection & Diagnostic Tracking: Fitted with designated fuses (F1–F8) protecting alarm bells, external power feeds, and logic rails; works directly with system software to flag dedicated display fault codes (e.g., Fault Code 83 / 93) upon a blown fuse.
3. High-Noise Immunity & Galvanic Isolation: Opto-isolated digital inputs and solid-state suppression diodes prevent engine room electromagnetic interference (EMI) and common-mode transients from disrupting central processor logic.
4. System Voltage Monitoring: Actively samples and references central 24 VDC power rails from the PSK-4 power unit, identifying supply-rail excursions (Fault 145 Low Voltage / Fault 146 High Voltage) and ground insulation breakdowns.
5. Plug-and-Play System Replacement: Direct form-fit-function mechanical profile and terminal arrangement allows quick shipboard swap-outs without rewiring harness looms or altering cabinet metalwork.

Applications

• Commercial Vessels: Cargo carriers, container ships, crude/chemical tankers, bulk carriers, and LNG/LPG carriers utilizing Salwico CS3000/CS3004 addressable safety installations.
• Passenger & Special Service Vessels: Ro-Pax ferries, cruise liners, offshore supply vessels (OSVs), tugs, and mega-yachts operating under strict SOLAS Chapter II-2 fire safety mandates.
• Offshore Energy Installations: Fixed production platforms, drilling rigs, and Floating Production Storage and Offloading (FPSO) units requiring type-approved marine fire detection infrastructure.
• Shipboard Subsystem Interfacing: Actuation of remote sounder lines, general emergency alarms (GA/PA mute signals), ventilation fan tripping, watertight door controls, and fire damper closure confirmation.

Frequently Asked Questions

What is the primary function of the Consilium Salwico IOK-4 board?

The IOK-4 is the main input/output and interface card for Salwico CS3000 and CS3004 fire alarm panels. It handles power distribution monitoring, fuses, alarm device actuation, and inter-board signal routing between the CPU and field circuits.

Are part numbers 051010 and 51010 identical?

Yes. Consilium often drops the leading zero in service bulletins and catalogue entries. Both 051010 and 51010 refer to the identical IOK-4 assembly.

What should I check if my CS3004 displays a persistent Fault Code 83 or 93?

Fault 83 indicates a blown fuse on the internal boards, while Fault 93 specifically references an alarm sounder/device cable break or blown output fuse. Check fuses F1 through F8 on the IOK-4 card with a multimeter, and inspect field cabling for physical damage or open EOL resistors.

Does replacing the IOK-4 board require software reconfiguration or reprogramming?

In most CS3000 and CS3004 systems, the system configuration data resides within the central processor (LPK-2 board) and memory EEPROMs. The IOK-4 acts as an interface hardware board. As long as replacement jumpers and hardware settings mirror the original unit, the board is direct plug-and-play.

Can I supply this board for an urgent vessel breakdown at a foreign port?

Yes. We support global vessel breakdown deliveries with expedited dispatch to major bunkering hubs and international dry-dock yards, coordinating handoff directly through nominated ship chandlers and vessel agents.
