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 have an interactive relationship between the control system (also known as the input circuit) and the controlled system (also known as the output circuit). 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 play roles in automatic regulation, safety protection, and circuit switching in 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 has two pieces of metal called "contacts." When the two contacts touch, they form a current loop; 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 working properly. Selecting contact metals also requires considering factors such as electrical conductivity, hardness, mechanical strength, cost, and toxicity. Sometimes, corrosion-resistant metals are plated onto the contacts. Plating is generally applied to the contact surfaces to avoid 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 have movable parts that make or break the contact. Switches can be classified into lever switches, push-button switches, rocker switches, etc., based on the different movable parts, and the movable parts can also be other types of mechanical linkages.

jura electrical component applications

Basic circuits of analog integrated circuits include current sources, single-stage amplifiers, filters, feedback circuits, current mirror circuits, etc. 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 response between the output and input signals of the former is usually linear; the shape of the output signal is similar to that of the input signal, only amplified by a fixed coefficient. The response of the output signal to the input signal in nonlinear integrated circuits exhibits a nonlinear relationship, such as square or logarithmic relationships, hence they are called 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-electric 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 signals such as sound, images, and radio waves for output.

jura electrical component classification

For most conductors, at a certain temperature, their resistance remains almost constant at a fixed value; this type of resistance is called linear resistance. For some materials, the resistance changes significantly with current (or voltage), and their volt-ampere characteristic is a curve; this type of resistance is called nonlinear resistance. 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. The methods for expressing nonlinear resistance characteristics are relatively complex, but these nonlinear relationships are widely used in electronic circuits.
