Solid State Relay Circuit Diagram
Solid state relay is a series that functions like a relay hibryd mechanics. Solid state relays is built with insulating an MOC for separate the input and the switch. With Solid state relays we can avoid the occurrence of sparks as it did in the relay can also avoid the occurrence of conventional connection is not perfect because porous contactor as in conventional relays.
The series of solid state relays This is quite simple and we can make in a PCB hole. For more details can be seen in the picture following a series of solid state relays.

Solid state relay has many advantages including no mechanical friction on the contactor, the connection process only occur when there are crosses zero, there is no spark at the contactor, not noisy, small konsusi flow control, better endurance.

Light Activated Relay
This is same circuit as above with the addition of a photo resistor to trigger the flip flop instead of a push button. The bias resistor in series with photo resistor was chosen so that sufficient voltage is present at the base of the 2N3904 to supply current to the circuit in ambient lighting conditions. The circuit should toggle when the photo resistor is hit by a flashlight beam or other fast changing light source. Slow changes in light intensity will have no effect unless the light gets too bright to maintain sufficient bias for the 2N3904.

Automatic Turn Off Relay
Per request the circuit today we have relay circuit. It is worth noting again that the diagram provides a time delay of about 0.5 seconds for every microfarad in the value of capacitor C1. This permits delays of up to several minutes. If desired, the delay periods can be made variable by replacing resistor R2 with a fixed and variable resistor in series whose nominal values are approximately equal of the total value of R2 (680K).

Pulse Timer Control Relay Circuit with IC555
Today we would like to offers solutions for a set time for take control relay and take NO. / NC. contact to apply to control other devices . such as disable or enable the device.function of this circuit is using IC555 to determine the pulse and a resistor R1 to the period of time.

R1 #Seconds
100k 2
220k 3
470k 6
1M 15
The increase provides more time to increase the value of the Capacitor.
Part List
R1 = 1 Meg, Preset Pot
R2 = 10K
R3,R4 = 1K
C1 = 10uF, 16V
C2 = 0.01uF
T1 = BC547 (Gen Purp NPN)
T2 = 2N2222 (Hi Current NPN)
D1 = 1N4001 (Gen Purp Si)
IC1 = 555 (Lo-Power version)
RLA1 = Relay, 9V (amps of your choice)
