Circuit Control YDCC-04

You can manage loads connected to the Circuit Control (firmware 1.01 or later is required) from most modern chart plotters with CZone support.

The Circuit Control and Switch Control are designed to be compatible with Oceanic Systems, Offshore Systems, Chetco Digital, Maretron 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;
• 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;

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.

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.
