Understanding Solid State Relays (SSR) Both zero-cross and random solid state relays are used for industrial applications. What are the differences between these two types of switching? Here are some answers. Zero-crossing Solid State Relays For ZERO VOLTAGE CONTROL (OR ZERO-CROSS RELAY), power switching only takes place at the beginning of the alternation after the […]

What is the difference between Triacs and Thyristors? AC switching solid state relays use back-to-back Thyristors and TRIAC’s as their built-in output switching device. What is the difference between Triacs and Thyristors ? Working principles of Thyristors and Triacs Thyristor (or SCR) Thyristor also called SCR stands for Silicon Controlled Rectifier. It is a semiconductor […]

What is a REED Switch? The REED switch is the sensitive element of the magnetic sensor. It detects the presence of a magnetic field, usually a permanent magnet. It detects without contact the position of the magnet and transmits an electrical on/off or analog signal depending on the model. Basic Principles A REED switch […]
