Solid State Relays: LBB120 Application Field and Working Principle

The LBB120 solid state relay is a leading scientific and technological product created by Siemens, which has been widely used in various high-tech fields, such as feeding, temperature control, lighting control and so on. This article will introduce the application area and working principle of the LBB120 solid state relay.

Application Field

1. LBB120 solid state relays are mainly used in fields with a large number of signals, such as automatic control, automatic testing, communication control, medical devices and others.2. In the field of power control, it is mainly used in motor speed control, welding machines, frequency converter output soft start, air compressor soft start and other fields.3. In the field of mechanical equipment, such as thickness control, cutting machine, injection molding machine, film winding machine, NC machine tool and other equipment.4. In the field of intelligent transportation, such as automatic control systems, traffic signal control, public transportation and other fields.5. In the field of energy and metering control, such as electricity metering, gas metering, heating metering and other fields.

Working Principle

The LBB120 solid state relay module is based on the principle of thyristor turn-on voltage. The voltage is used to control the current, and then a large current (source current) is connected to the output of the relay. It can be connected directly to the input of the switching device or into a constant current circuit, and control the input current of the switching device.When the relay is in the off state, the voltage across the anode and cathode of the thyristor is zero, and the current in the circuit is insignificant. When an external trigger voltage is applied, the voltage across the anode and cathode of the thyristor rises rapidly. When the voltage reaches a certain value, the thyristor is naturally turned on and the current can flow through. Therefore, the output current of the relay is supplied to the switching device, and the driving device is forced to operate and accomplish the switching action. When the external control voltage is removed, the voltage across the anode and cathode of the thyristor is forced to turn off, and the current in the circuit is also reduced to zero. Thus, the switch element is stopped and the driving element is turned off, accomplishing the disconnection action.The LBB120 solid state relay can respond in microseconds, and it has high performance and safety. The solid state relay has no mechanical parts inside and no sparking when turning on and off, thus it has high insulation capability. Compact and lightweight, the LBB120 provides convenient installation; it also has long service life and high reliability. With all these features, the LBB120 is ideal for any application in the fields of industrial control, intelligent transportation, robotics, automatic testing, medical devices, heating control, etc.
