Solid State Relays are one of the most widely used types of electronic switches available today. In fact, they are used everywhere from industrial equipment to consumer appliances. One of the most popular Solid State Relays on the market is the GNR20DCR, which offers a cost-effective and reliable switching solution. This article will discuss the application field and working principle of GNR20DCR Solid State Relays.

The GNR20DCR is a 2-channel Solid State Relay, designed to provide high retentance for both 20-volt and DCR signals. It is suitable for use in both open and closed loop control applications, and provides reliable performance in even the most demanding environments. With its high current capacity and low power consumption, it is ideal for a wide range of applications, such as motor control, lighting control, automated production equipment, robotics, and more.

The primary application field of the GNR20DCR is in the control of motors and electrical devices, due to its wide range of features and rugged construction.

The GNR20DCR uses an opto-isolator to provide isolation between the input and output circuits. By doing this, the GNR20DCR is able to achieve extremely low noise levels and a high level of accuracy in operation. It also has a fast response time of less than 100 microseconds, allowing it to switch rapidly between low and high voltage levels.

In terms of its working principle, the GNR20DCR uses a opto-isolator to switch between two voltage levels – low and high. The opto-isolator is connected to the input line, and when voltage is applied to the input line, it triggers the opto-isolator, which switches the GNR20DCR to the high voltage level. However, when the voltage is removed from the input line the GNR20DCR switches back to the low voltage level.

In addition to its fast switching speed and low noise characteristics, the GNR20DCR also features a built-in EMC immunity circuit. This circuit helps protect sensitive equipment such as computers and other electronics from interference. Moreover, it also provides additional protection against high voltage incidents due to its solid-state design.

The GNR20DCR is available in several different versions, including a three-way version for more complex applications. It has a wide range of applications, including motor control, lighting control, automated production equipment, robotics, and more. With its durability and reliability, it is one of the most popular Solid State Relays on the market today.
