Yacht Devices YDSR-01 Smart Relay 24V 15A, Bistable Relay

The Yacht Devices YDSR-01 Smart Relay is designed to manage two loads with a single power switch, making it ideal for scenarios such as combined deck/steaming lights on a mast with only two wires (positive and negative). This smart relay powers the first channel when you turn the power switch on and switches to the second channel when you cycle the power switch twice within one second.

Efficient Power Management

Equipped with a bi-stable RT424F05 relay, the device only uses power when switching channels, consuming less than 0.5 mA at all other times. It can handle 7-28V DC loads with continuous current up to 10A and peak current of 20A (for 4 seconds, with a 10% duty cycle). To switch between channels, simply cycle the power within one second. If one load needs to remain constantly on while the other switches, connect the first load to the incoming power terminals and the second load to channel 2.

Installation and Safety

Despite its waterproof design, the open terminals can be susceptible to short circuits if exposed to sea water. Therefore, it is crucial not to place the device where it can be flooded, get wet in the rain, or be sprayed with water. Always use an electrical fuse in your circuit to ensure safety.

Applications

The Smart Relay YDSR-01 is versatile and can be used for various applications, such as:

• Installing a bilge pump float switch
• Installing an additional fresh water pump

Technical Specifications

• Switches 7-28V DC loads with up to 10A continuous current
• Peak current: 20A (for 4 seconds, 10% duty cycle)
• Power consumption: less than 0.5 mA (when not switching)
• Four standard blade "FASTCON" terminals (6.3mm x 0.8mm)

The device is equipped with four standard blade "FASTCON" terminals, and five insulated receptacles are supplied with the device, which are widely available in electronics stores.

Important Note

Resistance between the active channel terminal and VCC terminal is always zero. Smart switching is managed by a microcontroller inside the device's case. High voltage (over 28V) on the VCC terminal can cause permanent damage to the device.
