CONSTITUTION:A control signal by a generating circuit 1 is temporarily stored in latching circuits 2, 3 alternately, exclusive OR4 is taken between temporary storage contents of the latching circuits 2, 3, and a driving signal of function relays Ry0-Ry3 is sent out. Accordingly, since the ...
12、relay is having function to trip a circuit breaker, contactor or equipment, or to permit immediate tripping by other devices. or to prevent immediate reclosing of a circuit interrupter if it should open automatically even though its closing circuit is maintained closed.Lockout relay is hand re...
The circuit uses an LDR (Light Dependent Resistor) as a light sensor, which, in simple terms, is a resistor whose value increases in darkness and decreases in the presence of light. Then it uses one transistor to detect the light, and another to drive the relay. When light falls on the...
A relay is a device that is often used as a switch in a circuit.According to the type of control voltage required by its coil, it can be divided into AC relay and DC relay.The specifications of the relay are represented by the coil control voltage and the contact current. Usually, when...
PURPOSE: A circuit having a relay in which a field coil and switches are built is provided to connect the field coil to the switches and a capacitor in series in a bistable relay, thereby charging the capacitor when the switches are turned on. CONSTITUTION: Relays(K1) comprise a field coil...
“normally-closed” switch is open. This open condition de-energizes relay coil CR1, allowing relay contact CR1-1 to spring-return to its normal status (closed), thus sending power to the alarm lamp. From this analysis we see that the lamp fulfills the function of a high pressure alarm,...

Why is a Diode so Crucial across a Relay Coil Whenever a relay is used in a circuit, you might have noticed a rectifier diode or a capacitor compulsorily connected parallel to the relay coil. This diode is called the flyback diode or the freewheeling diode. It is basically introduced to ...
AC switching elements are a crucial part of safety and protection function in charging stations and PV system. Key parts of the IVY line-up are the 40A IM-NE801A 2 pole power relay and 60A IM601 bistable relay. Both types are availabe with ...
