Time Delay Relays are one of the most popular automation technology used in today’s industrial applications. The 7022BDX application field and working principle is an example of this technology.

The 7022BDX is a solid state delay timer module made up of a thyristor switch and a solid state relay (SSR). It is used primarily for power switching and is ideal for controlling anything from simple appliances to complicated industrial machinery. It is designed to provide both electro-mechanical and programmable time delays.

The 7022BDX works by using an internal voltage regulator to detect and control the operation of the thyristor switch. When the voltage is applied, the thyristor activates the internal SSR and the SSR triggers the electrical timing operation. Depending on the configuration, the delay can range from 0.5 to 10 seconds.

Once the thyristor switch and SSR are triggered, the timing operation begins. A microcomputer is programmed to generate an internal clock signal at a frequency rate that is proportional to the voltage regulation. This clock signal is used to set the delay and calculate the amount of time that must elapse before the 7022BDX triggers the electrical control circuit.

The working principle of the 7022BDX is based on two factors – the applied voltage level and the frequency of the internal clock signal. When the voltage level exceeds the upper limit, the 7022BDX will activate its internal SSR, which, in turn, triggers the control circuit. The delay time is then calculated by the internal clock, using the frequency of the internal clock signal. This provides the user with an accurate time delay for power switching.

The 7022BDX is a low voltage, programmable, solid state timer module used for power switching and controlling any type of industrial equipment, including automated robots, actuators, and machines. It has the capability to provide both electro-mechanical and programmable time delays, and its internal voltage regulator is used to detect and control the operation of the thyristor switch. The delay can be adjusted from 0.5 to 10 seconds, depending on the configuration.
