jura electrical components are electrical control devices. When the change in the input quantity (excitation quantity) meets specified requirements, they cause a predetermined step change in the controlled quantity in the electrical output circuit. They exhibit an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). Typically applied in automated control circuits, they effectively function as "automatic switches" that use small currents to control the operation of large currents. Therefore, they serve functions such as automatic regulation, safety protection, and circuit switching in electrical circuits. A relay is an electrical control device that can accept a specified input quantity and maintain it for a sufficient duration to cause a predetermined step change in the controlled quantity in the electrical output circuit. When the input quantity drops to a certain level and remains there for a sufficient duration, it returns to its initial state.

jura electrical component structure

The simplest switch consists of two metal pieces called "contacts." When the two contacts touch, they complete the current circuit; when they do not touch, the current path is open. When selecting contact metals, their resistance to corrosion must be considered, because most metals form insulating oxides after oxidation, preventing the contacts from functioning properly. Selection of contact metals must also consider factors such as electrical conductivity, hardness, mechanical strength, cost, and toxicity. Contacts are sometimes plated with corrosion-resistant metals. Plating is generally applied to the contact surfaces to prevent performance degradation due to oxides. Sometimes non-metallic conductive materials, such as conductive plastics, are used for the contact surfaces. In addition to contacts, switches contain movable parts that make or break the contact connection. Depending on the type of movable part, switches can be classified as lever switches, push-button switches, rocker switches, etc., and the movable part can also be other types of mechanical linkages.

jura electrical component applications

Basic circuits in analog integrated circuits include current sources, single-stage amplifiers, filters, feedback circuits, and current mirror circuits. Higher-level basic circuits composed of these include operational amplifiers and comparators. Even higher-level circuits include switched-capacitor circuits, phase-locked loops, and ADC/DAC. Based on the response relationship between output and input signals, analog integrated circuits can be divided into two major categories: linear integrated circuits and nonlinear integrated circuits. The former typically exhibits a linear response between output and input signals; the output signal shape is similar to the input signal, only amplified by a fixed coefficient. In contrast, the output signal of nonlinear integrated circuits exhibits a nonlinear response to the input signal, such as square-law or logarithmic relationships, hence the term nonlinear circuits. Common nonlinear circuits include oscillators, timers, and phase-locked loop circuits. Typical applications of analog integrated circuits are shown in the figure below. External natural signals collected by various sensors or antennas—such as temperature, humidity, optical, piezoelectric, and acoustic sensors—are preprocessed by analog circuits and converted into suitable digital signals for input into digital systems. Signals processed by the digital system are then post-processed by analog circuits and converted into analog outputs such as sound, images, and radio waves.

jura electrical component classification

For most conductors, at a given temperature, the resistance remains nearly constant at a specific value; such resistors are called linear resistors. For some materials, the resistance changes significantly with current (or voltage), and their volt-ampere characteristic is a curve; such resistors are called nonlinear resistors. For a nonlinear resistor under a given voltage (or current), the ratio of voltage to current is the static resistance at that operating point, and the slope of the volt-ampere characteristic curve is the dynamic resistance. Expressing the characteristics of nonlinear resistors is complex, but these nonlinear relationships are widely applied in electronic circuits.
