8 Pin Relay Wire Diagram. Connect the h14 wire to the optional domelight supervision relay as shown in the following diagram. Figure 3221a high side driver relay driven led diagram an isolation relay circuit is recommended to avoid led flickering as shown above.
Fuse heater blower 9. Connect the h14 wire to the optional domelight supervision relay as shown in the following diagram. In the above 3 phase motor forward reverse wiring diagram.
The 7 pin n type 12n plug will still be used on o1 trailers and many towbar fitters will still offer the 7 pin socket as the cheapest alternative.
This type of relay allows you to wire two systems. Each relay on the board has the same circuit and the input ground is common to all eight channels. Thats all you done it in the above diagram i shown. The driver circuit for this relay module is slightly different compared to traditional relay driving circuits since there is an optional additional layer of isolation.
