Inspired by input from panel builders, system integrators and end users around the world, Rockwell Automation engineers developed the new Allen-Bradley E300 electronic overload relay. The E300 ...
The small, lightweight PTE-50-CE is the ideal instrument to test overcurrent and over/undervoltage protective relays, among many other applications. The reversible 100-VA amplifier can inject up to ...
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 ...
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 ...
