DP4R60D20 Application Field and Working Principle

Contactors (Solid State)

The DP4R60D20, or Direct Plug 4 Pole Relay, is one of the most common types of solid-state contactors on the market today. It is a low-cost, efficient solution for residential, industrial, and commercial applications, making it an ideal choice for a broad range of industries. The DP4R60D20 is used in a wide variety of applications including industrial automation, motor control, audio/video, and more.

As a solid-state, polar-sensitive device, the DP4R60D20 requires no external sources of power or manual resetting, meaning it can often survive and perform under adverse conditions. This makes it ideal for applications where automated systems are required or in harsh environments with limited or no access to manual resetting. The DP4R60D20 contains an N-Channel MOSFET which acts as a switch, allowing the device to be switched on and off with a low-voltage, low-current supply. The DP4R60D20 also contains a cathode and an anode, which are connected to terminals of the device.

The DP4R60D20 is designed to operate with loads of up to 6 amps, and its four contacts are rated for up to 4.5 kW at 240 VAC or 40 kW at 24 VAC. The device is also rated for a high temperature range of -40 to +85 degrees Celsius. This allows it to be used in industrial environments with wide temperature swings.

In order to operate the DP4R60D20, the user first needs to connect the listed input voltage to the terminal labelled “positive”. If the voltage is high enough, the device will switch on, allowing current to flow from the anode to the cathode. The user can then switch the device off by removing the input voltage from the same terminal. This on/off switching of the DP4R60D20 is what makes it an ideal choice for the application mentioned above.

Once the device is powered by the input voltage, the user can then connect the “NC” contact to a load. This will complete the circuit, allowing the current to pass through the device, powering the connected load. When the user switches the device off, the load will stop receiving power.

Overall, the DP4R60D20 is an ideal choice for any application that needs a reliable, efficient, and cost-effective contactors. Its low-voltage, low-current supply and wide temperature range make it a great choice for use in harsh industrial environments, and its durable design makes it a great choice for long-term use. With its ability to switch on and off quickly and easily, the DP4R60D20 is an excellent choice for any application.
