What Are The Three Power Relay Connections?

Jan. 05, 2019

Power Relay connection method:

When driving a relay with a transistor, it is recommended to connect the collector.

In addition, when the relay is ON, the rated voltage is applied, and when the relay is OFF, the voltage is zero. This is a method to avoid malfunction.

Collector connection

The most common connection method, the action is stable.

2. Emitter connection

Sometimes the consideration of the action is not to be used on the relay, no voltage is applied at all, and the transistor is not conductive at all.

3. Parallel connection

The overall power consumption of the circuit is increased, and the relay voltage needs to be considered.
