Time Delay Relays are used in various applications and can be found in many different industries. THD2C420 is no exception. It is an advanced, cost-effective, and reliable delay relay, developed for applications that require the ability to precisely control processes or operations over a specific period of time. It can be used for single-shot or repeat operations.

The THD2C420 relay uses timing elements and pulse-shaping circuitry to provide accurate and reliable time-delay triggers. It also has built-in features such as an adjustable delay time setting, adjustable voltage input, and a built-in quartz oscillator for precise time-delay accuracy. The adjustable second contacts on the THD2C420 are normally closed and open on a time-delay trigger.

The THD2C420 is designed to be used with Direct Current (DC) sources, including transistors, SCR’s, diodes, and AC/DC power sources. It is suitable for both single and multi-phase applications. The rated operating voltage of the THD2C420 range from 5V to 220V AC/DC, with a maximum current carrying capability up to 10 Amperes. The THD2C420 has two different models. The standard model (THD2C420-R1) has a fixed time period between 0.1 seconds to 10 seconds, while the other model (THD2C420-R2) has an adjustable time period between 0.1 seconds to 60 minutes. It has a wide operating temperature range from -10 °C to +80 °C, making it perfect for use in many different applications.

The THD2C420 performs various time-delay tasks by providing a time-delay trigger when either an input voltage or input current is applied, and releasing the trigger when the applied voltage or current goes away. The time period that elapses between the application and the release of the trigger is determined by the user programmable delay time setting. The adjustable second contacts will open upon completion of the time-delay cycle, interrupting the flow of electricity. This mechanical action then triggers the load device, allowing the user to control the timing of the load.

The THD2C420 can be used in a variety of applications such as industrial automation, process control, motor protection, and energy management, to name a few. It is an ideal device for providing precise timing, in environments where the timing needs to be consistently maintained. In addition, the THD2C420 also offers excellent protection against emissions, making it perfect for use in commercial and residential applications.

THD2C420 is a versatile and efficient time-delay relay, designed to provide accurate and reliable timing in any application. It is easily programmable, offers excellent protection from environmental influences, and is suitable for both single and multi-phase applications. With its wide range of operating voltage, adjustable delay time settings, and adjustable voltage input, the THD2C420 is an ideal choice for a variety of industrial and home applications.
