Yacht Devices YDCC-04 Circuit Control NMEA Sensor

Remotely control lights, pumps, and other onboard electrics with this 4-channel NMEA 2000 digital switching module. Each channel uses a latching (bi-stable) relay, so it only draws power during the moment of switching — not while holding a state — keeping standby consumption to just 30 mA on average. 

Key features:

• 4 channels: two normally-open (ON-OFF), two switching contacts
• Max constant load: 10A per channel (20A peak, 4 seconds)
• Handles AC and DC loads up to 400V, with high-voltage isolation (5000 VRMS)
• Can be managed from connected physical buttons with LED indicators, or remotely via a compatible NMEA 2000 network
• Works with most modern chartplotters supporting digital switching (check compatibility before purchase)
• Supports multiple units in parallel for larger systems — up to 252 unique bank numbers on a single network
• Simple installation — no special tools, software, or technical expertise required

Ideal for: bilge pumps, cabin and navigation lighting, and any onboard circuit you want to control or automate remotely.
