Overview
The Vimar VM01471 is a multifunction programmable actuator that gives you four relay outputs for switching onboard loads. Each output is a 16 A change-over relay for 120-230 V~ circuits, so it can be set up for lighting, blind or shutter slat orientation, and fan-coil control when used within a compatible automation system.
It mounts on a standard DIN rail (60715 TH35) and takes up 4 modules of 17.5 mm each, which helps keep a panel layout predictable during refits or new builds. With an IP20 protection rating, it belongs inside a dry, enclosed electrical cabinet or distribution panel rather than anywhere exposed to spray, washdowns, or bilge moisture.
Key features
- 4 programmable change-over relay outputs, rated 16 A per relay
- Switching for 120-230 V~ circuits
- DIN rail installation (60715 TH35) with a 4-module footprint (4 x 17.5 mm)
- Local push-buttons for on-unit operation and service checks
- Bus connection for integration with the By-me home automation environment
- IP20 protection rating for installation inside protected panels
Installation and setup
Plan for a DIN-rail position inside the boat’s electrical cabinet where wiring can be dressed cleanly and kept away from heat sources. The 4-module width makes it straightforward to line up alongside breakers, power supplies, and other DIN devices.
The local push-buttons are useful during commissioning and troubleshooting when you need to verify wiring and load response at the panel without relying on the automation interface.
Electrical and system integration
This unit switches AC loads (120-230 V~) through change-over relay contacts. A change-over relay gives you both normally-open and normally-closed behavior from the same channel, which can matter when you need a default state or interlock behavior in a boat system.
Match each output to the real load current and how the load behaves at startup, then protect the circuit appropriately in the panel. Keep terminations tight and well-supported so vibration does not work connections loose over time.
Use cases on board
Common uses include switching lighting circuits, driving paired outputs for blind or shutter movement with slat orientation functions, and controlling fan-coil stages within a networked control scheme. It is a good match for yachts that already use the By-me automation environment and want a DIN-rail relay module to bring multiple AC loads under centralized control while still keeping local access at the panel.
Maintenance and care
Because it is IP20, keep it in a clean, dry enclosure and avoid mounting locations where condensation or water ingress is likely. As part of routine electrical checks, re-torque terminals and inspect wiring support, especially after heavy-weather runs or long periods of vibration.
Shipping
We ship worldwide from the United States. Rates are calculated at checkout based on destination and package weight. Some items include free shipping, which will show automatically. Not every product is eligible for international shipping; checkout will confirm eligibility. We do not ship to PO Boxes except through USPS, and not all packages qualify.
Processing and dispatch
Most orders are verified, packed, and handed to the carrier within 1 to 2 business days. Some products may need extra handling time or ship directly from the manufacturer. For certain international orders, inventory transfers between warehouses may add time. If any delay is expected, we will let you know the dispatch date.
Delivery and tracking
Deliveries are handled by trusted carriers such as USPS, UPS, FedEx, and DHL. Estimated arrival times appear at checkout and depend on your location and the service you choose. These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.
Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.
Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.
Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.
To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
