Additionally, it has a high degree of flexibility, as it can be used to switch both AC and DC loads, making it suitable for a wide variety of applications. The G3MB-202PLEG-4 DC20MA can be used in a wide range of environmental conditions, from -20°C to +70°C. Additionally, it has an ingress protection rating of IP50, making it suitable for use in dusty environments. The G3MB-202PLEG-4 DC20MA also has a wide range of features including short circuit protection, surge protection, and over-temperature protection, making it an excellent choice for applications requiring high reliability.

Working Principle

The G3MB-202PLEG-4 DC20MA works by using both an optically coupled isolation element and an electromagnetic relay. When the control signal is applied, the optically coupled element produces a current that turns the electromagnetic relay on. This allows the power to flow to the output and the device is switched on. When the control signal is removed, the optically coupled element produces no current and the electromagnetic relay is turned off. This disconnects the power from the output and the device is switched off.

The G3MB-202PLEG-4 DC20MA also has a high isolation voltage rating of 1.5kV, which ensures reliable switching and prevents any arcing between the input and output. Additionally, the device has a high switching current of 20mA, which enables the device to be used in applications with higher loads. Finally, the G3MB-202PLEG-4 DC20MA has a low on-state resistance of 70mΩ, which allows the device to be more energy efficient, as well as increase its current-carrying capability.

The G3MB-202PLEG-4 DC20MA is a versatile device that can be used in a wide range of applications, providing reliable and efficient switching and control functions. Its wide switching current and low on-state resistance make it an excellent choice for applications requiring high reliability and energy efficiency.
