Solid state relay normally closed
WebNC (Normally Close): If the throw circuit is connected to the pole by default (when the pole is not energized or charged or the voltage level on the pole is zero), this throw circuit will be called the normally closed circuit (NC circuit, N/C circuit), and the solid state relay switch will be called normally closed SSR switch (NC SSR switch, N/C SSR switch). ① Push-Pull …

WebThe basic techniques for suppression of transient voltages from relay coils are shown in Figure. As observed here, the suppression device may be in parallel with the relay coil or in parallel with the switch used to control the relay. It is normally preferred to have the suppression parallel to the coil since it can be located closer to the ... WebOct 12, 2024 · Now let's understand how a relay works in a normally closed condition and normally open condition. Relay in NORMALLY CLOSED condition: When no voltage is applied to the core, it cannot generate any magnetic field and it doesn’t act as a magnet. Therefore, it cannot attract the movable armature. Thus, the initial position itself is the ...
