Electromechanical components such as relays and switches often must undergo endurance tests that verify their reliability and safety. Regulatory standards typically have compliance criteria that ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

Production test of a finished electronic product often involves two techniques: in-circuit test (ICT) and functional component test (FCT). The ICT technique examines a non-powered circuit board to ...

Testing verifies that protection schemes meet their intended purpose, ensuring safety and system integrity. Function testing involves manual or electrical manipulation of components to confirm signal ...

The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...

Electronic relays have evolved a lot since their introduction in the early '30s, but their basic purpose hasn't changed. Transistors and integrated circuits have replaced vacuum tubes and the term has ...
