OctoPlex Gen1 and Gen2 - DC POWER ISOLATOR, 10 CIRCUITS - Prevents current feedback

The Raymarine OctoPlex A1940 DC power isolator is a critical component designed for first- and second-generation OctoPlex power management systems. This specialized module manages 10 separate circuits, providing electrical isolation and effectively preventing unwanted backfeed within the vessel’s electrical network.

The primary function of the A1940 isolator is to ensure the stability of DC power circuits by preventing current feedback. This is crucial for protecting sensitive electronic equipment and maintaining a stable power supply across the 10 circuits it serves.

The Raymarine OctoPlex A1940 DC power isolator is designed to manage 10 separate circuits.

The A1940 DC power isolator is specifically designed to be compatible with OctoPlex electrical management systems of Generation 1 (Gen1) and Generation 2 (Gen2).

Yes, the A1940 isolator is a component that integrates with the OctoPlex system, which is an NMEA 2000-certified power distribution platform. It is therefore designed to operate within an NMEA 2000 network.

Yes, the OctoPlex system is NMEA 2000® certified, category B. This certification ensures compliance with marine industry standards for equipment interconnectivity.

Integrating the A1940 isolator into the NMEA 2000 OctoPlex network simplifies electrical management, resulting in a significant reduction in wiring complexity and overall weight aboard the vessel.

Yes, by preventing undesirable reverse currents and ensuring electrical isolation for 10 circuits, the A1940 isolator is crucial for protecting sensitive electronic equipment and contributes to the reliability and electrical safety of the onboard system.

The OctoPlex system, and by extension its components such as the A1940, is certified:

CE ApprovedIEC60533 (Electrical and electronic installations in ships)IEC60945 (Marine navigation and radio communication equipment and systems)NMEA 2000® Approved (Category B)Lloyd’s Type Approved (Test Specification #1, ENV2 Certificate No. 10/00021)

Yes, it is important to note that OctoPlex products are not ignition-protected devices and must not be installed in areas where combustible vapors may be present.

Yes, periodic inspection of all fastenings and connections is recommended to ensure proper operation and system safety.

The OctoPlex system uses a redundant architecture based on a CAN bus NMEA 2000 network, which eliminates single points of failure. This design, which the A1940 isolator enhances by securing the circuits, significantly improves the reliability and safety of the electrical system.

Yes, the OctoPlex system allows centralized control and monitoring of AC and DC loads on board via its NMEA 2000 CAN bus network, providing complete energy management.

The OctoPlex system is designed for monitoring and controlling the vessel’s AC (alternating current) and DC (direct current) loads. It also enables remote control of field-replaceable AC and DC circuit breakers.

No, the A1940 isolator, like all other OctoPlex products, is not an ignition-protected device.

Yes, in addition to power distribution, the OctoPlex system enables monitoring and control of common NMEA 2000 marine devices such as compasses, GPS, tank level adapters, and others.

Yes, the OctoPlex system, via the MConnect web server, supports integration with MFD manufacturers, including Garmin OneHelm™ and Raymarine® Axiom.

Yes, the Raymarine OctoPlex A1940 DC power isolator is covered by the manufacturer's standard warranty. For detailed warranty information, consult Raymarine's specific terms and conditions.

Yes, the OctoPlex installation guide also serves as a troubleshooting guide that can help ensure the system operates at its full potential as designed or intended.
