The HF321S is a 4-pin SPST-NO (Single Pole Single Throw - Normally Open) relay. It consists of the following pins:
1. Coil terminals (2 pins): These are used to energize the relay coil. When voltage is applied across these terminals, the coil gets energized, creating a magnetic field that pulls the armature to close the contacts.
2. Common terminal (1 pin): This is the moving part of the relay that connects to the normally open contact when the relay is energized.
3. Normally Open terminal (1 pin): This contact is open when the relay is in a de-energized state. It closes to the common terminal when the relay is activated, thus completing the circuit.
The HF321S is typically used in applications where you need to control a high power or high voltage circuit with a low power signal, providing electrical isolation between the control and load circuits.
