H11L3SR2M Isolators

Optoisolators - Logic Output is a class of electrical components that isolate one circuit from another. The H11L3SR2M component, traditionally used in electrical switching circuits, is a 4-channel Optoisolator Logic Output. It offers the highest level of signal isolation between high-voltage logic signals and low-voltage control signals in a variety of applications. This article will discuss the application field and working principle of the H11L3SR2M.

Application Field of H11L3SR2M

The H11L3SR2M is used to isolate input signals from the output signal in a variety of applications. It is commonly used in industrial automation, medical equipment and computer networks. The high isolation resistance and low propagation delay of the H11L3SR2M enables electrical isolation between its input and output circuits. This prevents interference between high voltage logic signals, away from low-voltage control signals.

The H11L3SR2M is also well suited for controlling relays for power switching applications. It can be used in place of a relay to control electrical circuits without transfer of power. It is also used in control circuit designs of elevators, automated production lines, DC motor control and other control applications.

Working Principle of H11L3SR2M

The H11L3SR2M utilizes an optical isolator to provide electrical isolation between the input and output sides of the device. It is made up of a pair of LEDs that are placed next to each other, one on the input side and one on the output side. When a logic signal is applied to the input side, the LED on the input side emits light, which is then detected by the LED on the output side. This triggers an on-off switch on the output side of the H11L3SR2M, allowing the logic signal to pass through and be isolated from any downstream circuits.

The H11L3SR2M is configured in a single line, requiring less space than other components. It can be used in circuit designs between low voltage control signals and high voltage logic signals, providing signal isolation from noise and other interference. Furthermore, the switch impedance is optimized for controlling the amount of current that passes through the circuit, allowing it to operate efficiently and reliably.

Conclusion

The H11L3SR2M is a 4-channel Optoisolator Logic Output component that provides high signal isolation between high-voltage logic signals and low-voltage control signals. It is ideal for applications such as industrial automation, medical equipment, computer networks and power switching circuits. Furthermore, the H11L3SR2M utilizes an optical isolator to provide electrical isolation between the input and output sides, allowing it to operate efficiently and reliably.
