Five different relay and solid state relay

by:Positioning     2021-05-15
The contrast of traditional relay and solid state relay, because involves sort is more, the following with electromagnetic relay and solid state relay corresponding comparison shows that the difference between them: 1, the structure difference: electromagnetic relay circuit using the input circuit in the electromagnet core and the effects of the suction between armature and work; Solid state relay with electronic components to fulfill its function without mechanical components, input and output is isolated. 2, work way difference: the electromagnetic relay is using the principle of electromagnetic induction, through the strength of the electromagnet to control circuit on and off, therefore, direct current coil, contact can hand over, direct current (dc); Solid state relay on semiconductor devices and electronic components of electric, magnetic and optical properties to complete its isolation and relay switch function, therefore, the dc input The ac, dc input A tributary of the output type, ac input Input - ac output type, communication Dc output type. 3, work status difference: use the suction effect between armature electromagnetic relay, and broken circuit, therefore, action is slow, noise, limited life; Solid state relay response is fast, running without noise, long service life. 4, the use of the environment: temperature, humidity, atmospheric pressure, The altitude) , sand dust pollution, chemicals, and elements such as influence of electromagnetic interference, electromagnetic relay is generally not as good as solid state relay. 5, electrical performance difference: electromagnetic relay and solid state relay is accordingly, the former driver is simple, but big power consumption, good isolation, short-time overload resistance is good, is inferior to the latter control large current, high power, control action faces the complex circuit, longer life expectancy than the latter. In a word, the traditional relay and solid state relay contrast, the latter because of its reliable work, non-contact, no spark and long life, no noise, no electromagnetic interference, fast switching speed, more and more popular. Solid state relay true experts, in order to your satisfaction, we really heart. If interested in our solid state relay or there is doubt, welcome your consultation.
