Optoisolators - Logic Output: H11L3M-V Application Field and Working Principle

Optoisolators are devices used to electrically isolate two different circuits and, via the optical interface, to pass along signals and data from one circuit to another without the risk of interference or electrical shock. They are primarily used in sensitive electronics, such as industrial control and data acquisition equipment, to guard against electrical surge, Voltage spikes, and static, chemicals, or water-based physical damage. The optoisolator chosen for this article, the H11L3M-V, is a type of optoisolator that uses logic output with a voltage LED output for binary coding of optical signals.

General Description

The H11L3M-V is a single-channel optoisolator with an optically-coupled logic output and a voltage LED output. It has an open-collector phototransistor output driver, with a maximum voltage of 30V and a minimum current of 10mA, enabling it to be used as a feedback signal for wide range of digital and analog applications. It also includes a PIN diode that helps reduce photocurrent noise and further isolates the output from the input circuit. It also has a minimum isolation of 1000Vrms between input and output circuits, which helps protect against electrical surges and protects the input circuit from harmful mechanical hazards. Additionally, it has an operating temperature range of -30°C to 100°C and a data rate of up to 100kbits/sec.

Application Areas of H11L3M-V

Optoisolators are primarily used in a variety of industrial and consumer applications, such as control systems, data acquisition equipment, signal processing, measurement and monitoring systems, medical equipment, and more. The H11L3M-V can be used in a variety of applications, including:

• Communication systems
• Industrial automation systems
• Data processing equipment
• Medical systems
• Electrical power measurement
• Testing and monitoring systems

The Working Principle of H11L3M-V

The basic working principle of the H11L3M-V is as follows: the input side of the optically-coupled isolator contains an LED and a PIN diode. The PIN diode is used to reduce the amount of light reaching the output side of the device in order to control the photocurrent noise. The LED is driven by voltage, which causes it to generate light that is then converted by the phototransistor into a current signal. This current signal is then used as feedback to control the operation of the output driver. The output of the H11L3M-V can be used to control the level of voltage or current on the output side of the device, or to control the on/off state of the output circuit.

Advantages of H11L3M-V

The H11L3M-V optoisolator offers several advantages, including:

• High isolation between input and output circuits, up to 1000Vrms.
• Low power consumption.
• High speed operation, up to 100kbits/sec.
• Compact design.
• Wide operating temperature range.
• Low cost.

Conclusion

The H11L3M-V optoisolator is an ideal choice for a wide range of applications where electrical isolation is needed. Its wide operating temperature range, high isolation rating, and low cost make it an excellent option for many industrial and consumer applications. Its PIN diode output helps reduce photocurrent noise, while its open-collector output allows for wide range of digital and analog applications. The H11L3M-V is an excellent optoisolator for applications where electrical isolation is necessary.
