Circuit Control YDCC-04

The Circuit Control contains four latching (bi-stable) relays, which can be managed from connected control buttons with LED indicators or over NMEA 2000 with standard messages.

The Circuit Control is the core component of our digital switching system. In addition to connected buttons, loads can be managed from modern chart plotters, with "virtual buttons" on the Web Gauges of our Wi-Fi Gateway, or automatically from our sensors. To set up additional control posts with duplicate physical buttons and indication, use Switch Control YDSC-04.

The diagram above shows how the floating switch and the bilge pump are connected to the Circuit Control. The 16-mm button with integrated LED switches the pump between manual and automatic modes, and indicates the actual state. The pump can be also controlled from your smartphone. The Web Gauges page of the NMEA 2000 Wi-Fi Gateway (which is connected to the 2-Way NMEA 2000 connector) is open on the screen. The pump can also be mananged from buttons connected to the Switch Control (also connected to the 2-Way NMEA 2000 connector).

Device terminals are shown in Appendix C. Electrical characteristics of the Circuit Control:

  • four channels: two with normally open contacts (ON-OFF) and two with switching contacts;
  • latching (bi-stable) relays consume electricity only during the process of switching and stay in their last state after the device is powered off;
  • maximum constant load current per channel is 10A, peak is 20A (4 seconds, duty cycle 10%);
  • capable of switching the direct current (DC) and alternating current (AC) loads up to 400 V;
  • high voltage isolation with a load, 5000 VRMS;
  • average device consumption is only 30 mA.

  • Basic system, with single Circuit Control unit
  • Typical system, with multiple control panels
  • Parallel loads, synchronized Circuit Control units
  • Two independent digital switching systems (different bank numbers)

Figures 1-4. System examples (use slider)

The Circuit Control unit can work in parallel with other units and can be managed from multiple Switch Control units with a matched bank number (252 unique bank numbers are allowed in NMEA 2000). Multiple independent digital switching systems (with different bank numbers) can co-exists in a single NMEA 2000 network. Use the slider shown in the above diagram to check examples of digital switching systems.

You can manage loads connected to the Circuit Control (firmware 1.01 or later is required) from most of modern chart plotters with CZone support. This includes Garmin, Lowrance, Simrad, B&G, Furuno chart plotters and recent models from Raymarine (Axiom, eS and gS series). Click here to configure your MFD. EmpirBus digital switching products (supported in old Raymarine MFDs) are not supported yet.

The Circuit Control and Switch Control are designed to be compatible with Oceanic Systems, Offshore Systems, Chetco Digital, Maretron (see p.27 in the Manual) and Carling Tech displays and relay modules, and with other NMEA 2000 digital switching devices managed with standard NMEA 2000 PGN 127501 "Binary Status Report" and PGN 127502 "Binary Switch Control".

Product benefits:

  • compatible with a wide range of equipment, including modern chart plotterts;
  • no special requirements for buttons, you can choose any momentary push buttons to match your boat's interior (see p.19 in the Manual);
  • no special knowledge, software or hardware is required for installation;
  • price and size are suitable for small vessels;
  • any type of load is allowed (AC, DC, audio);
  • no heating, no extra power consumption;
  • pure NMEA 2000 product, compliant to the Standard and certified by NMEA;
  • high-voltage isolation with the load;
  • support firmware updates, free software for PC is available (Wi-Fi or USB Gateway is required).

The Circuit Control is certified by National Marine Electronics Association and is designed for operation in an NMEA 2000 network. It is supplied with a NMEA 2000 Micro Male connector; the drop cable is not supplied with the device and should be purchased separately. For connection to Raymarine SeaTalk NG network use cables with Raymarine part numbers A06045 or A06075.
