Top design objectives for control installations include capability, reliability, and cost effectiveness. Many new and retrofitted control panels employ components such as PLCs and even industrial PCs (IPCs) and programmable automation controllers (PACs) for advanced connectivity and control. It’s often appropriate to use these more complicated (and capable) options and remove or forgo electromechanical relays […]
Solid-state relay characteristics and applications
Solid-state relays (SSRs) serve the same functions as electromechanical relays but are non-moving noncontact devices that can switch voltages to several hundred Vac for hundreds of thousands of cycles and beyond … which makes them useful for switching heating elements, motors, and transformers needing frequent and high-speed switching. ⚙️ Download this article (and the rest…
Comparing solenoids and contactors with electromechanical relays
For some the words solenoid and relay conjure visions of an ancient electromechanical world now replaced by all-electronic devices, smart motors, and more. That almost makes sense, as these two components in various forms have been with us for over 150 years. But don’t be fooled: Both are still indispensable devices … and remain viable…
DIN rail: Basic construction and versions
The ubiquitous nature of components for DIN-rail mounting makes this standard particularly helpful … especially when panel redesigns are in order. Here, a technician need only to unclamp components, slide them to their new locations, and reclamp them to the DIN rail. In addition, DIN rail prevents upside-down and other incorrect installation. A typical DIN […]
Basics of terminal blocks and their various subtypes
Download this article (and the rest in our connectivity series) at the Design Guide library.

Comparing the two main relay types: Electromechanical and solid-state relays in automation
Relays are electronic devices that accept current or voltage signals in an input circuit as a prompt to switch open or close another circuit or pilot device. In this way, relays are switches that are controlled by some other input. The output is to trigger a predictable state change in the connected system. Variations abound:…
