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; a
verage device consumption is only 30 mA.
