Optoisolators are an important type of device for achieving electrical isolation. The EL3H7(H)(TB)-G is an optoisolator specifically designed for applications requiring high speed switching transistors as outputs. These optoisolators feature an LED input, which, when activated, causes a photovoltaic cell to close a circuit, triggering an NPN transistor output. This output can be used to open or close circuits, allowing for remote switch control.

The EL3H7(H)(TB)-G provides several unique features. First, it has a low system response time, with a typical turn on delay of only 5 milliseconds. This fast response allows for quick switching of a load, making this device viable in situations where response time is critical. Second, the device is extremely efficient with a current transfer ratio of up to 2000%. This ensures that the output signal is quickly activated, without significant voltage drop.

The EL3H7(H)(TB)-G also provides high levels of optical isolation. This means that the LED input can be electrically insulated from the physical switch. This allows the device to be installed in hazardous places such as hazardous areas, without the risk of electrocution or other safety hazards.

Finally, the EL3H7(H)(TB)-G has a maximum working voltage of 70V, which makes it suitable for use in higher voltage applications. In addition, the device has a low-sensitivity output, allowing it to be driven by low-level signals. This makes it ideal for highly sophisticated control systems.

In terms of its working principles, the EL3H7(H)(TB)-G is powered by a 12V power supply. When the LED input is activated, it closes a circuit which triggers the photovoltaic cell, thus allowing current to flow through the NPN transistor output. This current can then be used to open or close an external switch, allowing for remote control.

The EL3H7(H)(TB)-G can be used in a variety of applications. It is commonly used in industrial automation systems, to control various equipment such as robots. It can also be used in data acquisition or monitoring systems, to activate switches and signals. In addition, the device can be used in medical devices, providing reliable switching capabilities for controlling patient monitoring equipment.

Overall, the EL3H7(H)(TB)-G is a versatile optoisolator, providing a fast response time and efficient current transfer for reliable switching applications. Its unique features make it suitable for a wide range of applications, from industrial automation to medical monitoring. The device allows for safe installation in hazardous areas, thanks to its optical isolation capabilities. Finally, its low-sensitivity output allows it to be driven by low-level signals, making it ideal for sophisticated control systems.
