Relays are electrical switches used to control the flow of electrical current. Mechanical relays use mechanical contacts and electromagnets to switch currents, while solid-state relays (SSRs) use semiconductor devices to switch currents. Solid-state relays are more reliable and last longer than mechanic...
According to the structure, the relays can be divided into mechanical relays (such as electromagnetic relay, electromechanical relay or EMR) and non-contact relays (solid state relay or SSR).The working principle of the mechanical relay is the principle of electromagnetic induction. The structure of...
they are very similar to the electromechanical relays we are familiar with. But the solid state relays don’t have any mechanical parts, instead, they use solid state devices such as triacs as switching elements
Mechanical Relays Magnetic contactors and solid state relay modules VIEW PRODUCTS » Solid State Relays Complete or interrupt a circuit electrically with no moving parts, quick and easy. Solid-state relays are offered in many styles and sizes. VIEW PRODUCTS » ...
The advantages Solid State Relays (SSR) have compared to Electro Mechanical Relays (EMR) are well-known. Fully electronics, there is no moving parts inside SSR ; they have no audible noise, withstand significant vibration without operating problems, have fast response time, but most of all they...
How To Use Push-Pull Transformer Drivers To Replace Solid-State And Mechanical Relays Matthias Thoma, Field Applications Engineer Manuel Chavez, Applications Engineer Anant Kamath, Systems Engineer Introduction Electromechanical relays (ERs) and solid-state relays (SSRs) are widely used in industrial and...
–Relays generally have a higher current rating than transistors, but, as with any mechanical device, it will wear out with time. –A relay module can operate AC or DC loads, or both. –Relays provide electrical isolation between the load and the PLC. –Relays are slow-acting with typical...
