Power relays serve to control the flow of electricity in different electrical systems. They switch on and off between low voltage and higher voltage sources. The ST2-L2-DC9V relay is part of a wide range of power relays that can handle currents up to and beyond 2 Amps.

The ST2-L2-DC9V features a single-pole, double-throw (SPDT) configuration. The relay has a 9-volt coil, which is designed to be activated by a 9-volt direct current (DC) power source. The relay is capable of switching between two different outputs, which are electrically isolated from each other. The two output contacts are rated for 5 Amps at 125VAC/30VDC each.

The primary application field for this particular relay type is switching and protection. Examples where the ST2-L2-DC9V relay can be used include switching on/off a motor from an electronic control circuit, signaling an alarm after a predetermined current has been exceeded, and other forms of switching and protection in general.

The working principle of the ST2-L2-DC9V relay is simple. When the relay is inactive, the switch or contact is generally closed. When voltage is applied to the coil, the contact opens, allowing a different current or voltage to pass through. When the voltage to the coil is removed, the contact closes again. In this way, the relay can be used to control different electrical circuits and components safely.

The ST2-L2-DC9V power relay is a versatile, reliable, and easy-to-use solution for many different electrical switching and protection applications. It features a well-designed SPDT configuration and can handle currents up to 2 Amps. The primary application fields are mainly switching and protection, and the working principle of the relay is simple and effective.
