Our Radio World colleague Charles S. “Buc” Fitch, P.E., recently completed a relay interface assembly for controlling an older auxiliary transmitter. Late-model transmitters have remote control ...

When it comes to electronics, it seems like a relay is such a simple device – yet, it is able to interface some pretty elaborate high-end systems with a fire alarm system. Working with relays is an ...

Many microcontroller designs typically mix multiple interfacing methods. A microcontroller (µC) system can be viewed as a system that reads from inputs, performs processing and writes to outputs.

New space-saving slim electromechanical relays are now available from AutomationDirect. Klemsan Series slim interface relays are compact and lightweight relays especially useful where cabinet space is ...

These electromechanical relays measure just 70 mm high, and are suitable for panels with limited room. They work particularly well in higher load switching applications, industrial automation panels ...
