NABCO MC-507-01A PCB Card

Description

Key Technical Specifications

Current specialist inventory records identify the NABCO MC-507-01A as a PCB card with part number 882 72742923, additional identifier K0911976, and a listed weight of 490 g. One inventory record also gives reference number PC497/0.500.

⚠️ Technical limitation: The sources reviewed do not establish the board’s exact supply voltage, I/O channel count, signal ranges, communication protocol, operating temperature, or power consumption. These values should be verified from the applicable NABCO documentation or the actual board markings rather than inferred.

Product Introduction

The NABCO MC-507-01A is a NABCO printed circuit board used in marine and industrial control equipment. Current specialist listings identify the board as 882 72742923, with K0911976 also associated with the unit.

This part is primarily relevant to maintenance of an existing NABCO installation where retaining the original system architecture is preferable to modifying the control equipment. Because detailed OEM electrical specifications are not publicly verified, confirm the complete board identification and system compatibility before ordering.

Installation & Configuration Guide

Stage 1: Pre-Installation Preparation — Approximately 10 Minutes

⚠️ Safety First: Coordinate the maintenance window with vessel operations. Put the affected control equipment into its approved safe state, isolate electrical power, and apply the applicable lockout/tagout procedure.

Tools Required

• ESD wrist strap
• Grounded ESD work surface
• Appropriate screwdriver set
• Digital multimeter
• Wire and connector labels
• Smartphone or camera
• NABCO system drawings and maintenance documentation

Data Backup

1. Record the complete MC-507-01A designation.
2. Record 882 72742923 and K0911976.
3. Photograph the complete PCB before removal.
4. Photograph every connector and terminal.
5. Record jumper, switch, and link positions if fitted.
6. Photograph the surrounding rack or mounting arrangement.
7. Retain the original PCB until the replacement has completed functional testing.

⚠️ Do not rely on the model number alone. The available inventory records contain multiple identification fields for this board. Match the physical markings against the procurement information before installation.

Stage 2: Removing the Old Module — Approximately 5 Minutes

1. Confirm that the controlled equipment is in a safe maintenance state.
2. Isolate the applicable power source.
3. Establish ESD protection before touching the PCB.
4. Remove the required enclosure or rack cover.
5. Photograph the installed MC-507-01A and its connectors.
6. Label connectors where there is any possibility of confusion.
7. Disconnect connectors carefully without pulling individual wires.
8. Release the PCB retaining hardware.
9. Remove the card without bending the PCB.
10. Inspect mating connectors, pins, and the mounting area for corrosion or mechanical damage.

⚠️ Keep the original card nearby. For legacy marine equipment, the installed board is often the most reliable reference for connector orientation and configuration.

Stage 3: Installing the New Module — Approximately 5–10 Minutes

1. Verify the replacement marking: NABCO MC-507-01A.
2. Verify part number 882 72742923.
3. Check the additional identification K0911976 where applicable.
4. Compare the connector layout with the removed board.
5. Confirm board orientation before insertion.
6. Install the PCB without forcing connectors or mounting points.
7. Secure the board using the original mounting hardware.
8. Reconnect each connector according to the photographs and approved wiring documentation.
9. Confirm that every connector is fully seated.
10. Check for trapped wires, loose hardware, or conductive debris.

Configuration Clone — Critical

If the original board has configurable switches, jumpers, or links, reproduce the documented settings exactly.

Do not assume factory-default settings are appropriate for the installed NABCO system.

Pre-Power Checklist

• MC-507-01A model verified
• 882 72742923 part number verified
• K0911976 identification checked
• Board orientation correct
• Connector arrangement verified
• Wiring checked against photographs
• Configuration settings documented
• Mounting hardware secured
• PCB visually inspected

Stage 4: Power-On & Testing — Approximately 10 Minutes

1. Perform a final visual inspection.
2. Confirm that no tools, loose screws, wires, or conductive debris remain inside the enclosure.
3. Verify the applicable supply circuit against the system documentation.
4. Restore power using the approved startup procedure.
5. Observe PCB and system status indicators.
6. Check for new system alarms.
7. Verify communication with associated control equipment where applicable.
8. Perform the manufacturer’s prescribed functional test.
9. Confirm relevant control signals and feedback.
10. Record the board identification and test results in the maintenance log.

⚠️ Do not assign specific LED meanings or electrical limits without the correct NABCO documentation. The public inventory records establish the model and part number but do not provide a reliable diagnostic or electrical specification for this exact board.

Frequently Asked Questions (FAQ)

What is the NABCO MC-507-01A?

The NABCO MC-507-01A is a printed circuit board card used in marine/industrial equipment. Current specialist listings identify it as 882 72742923.

What is the part number for NABCO MC-507-01A?

The principal part number identified by current inventory sources is 882 72742923. is also associated with the product in specialist inventory records.

What is the weight of the MC-507-01A?

A current specialist listing gives the unit weight as approximately 490 g.

Is the MC-507-01A a PLC CPU?

It should not be described as a conventional PLC CPU without supporting OEM documentation. The available records identify it as a PCB card, but they do not provide sufficient information to establish its exact internal control function.

Can the NABCO MC-507-01A be hot-swapped?

Do not assume that it can. The sources reviewed do not document a hot-swap procedure for this specific board. Unless the applicable NABCO system documentation explicitly permits energized replacement, isolate power before removing the PCB.

Is NABCO MC-507-01A obsolete?

The sources reviewed do not provide an official NABCO end-of-life statement. However, current market availability appears concentrated in specialist marine-spares inventories rather than standard current-production distribution. Therefore, verify lifecycle status directly if this board is being added to a long-term critical-spares program.

Is the MC-507-01A available new?

Current specialist listings reviewed identify the available units as Used. Aeliya Marine lists the MC-507-01A as used, and another marine-parts listing likewise specifies Used condition.

If your application requires New Original / New Surplus, request photographs and written condition confirmation before issuing a purchase order. For used stock, request inspection and functional-test information, especially for a board intended for a critical marine control system.
