The 859 Series DIN-rail timer relay module offers on-/off-delay timer modes and multiple time ranges for applications such as switch and package de-bounce sensors. Untraditionally, the 6-mm components ...
What is the point of reviewing a cheap timer module, especially if it is based on the ubiquitous 555 timer chip? Recently I got an ‘updated’ version of the common 555 timer relay module. This time it ...
Wago Corporation’s Triggered Timer Relay supports E-stop circuitry within space-restricted panels. Upon E-Stop activation, the falling edge of a trigger signal initiates the 859-477’s off-delay timer ...
We often marvel at the many things a 555 can do. But [Zafer Yildiz] shows us that it can even take the place of a PCB. You’ll see what we mean in the video below. The timer relay circuit is built ...
Protective relay testing verifies that installed relays will trip correctly under real fault conditions, confirming settings, ...
Sometimes, the most unexpected detours lead to the most interesting discoveries. After a brief break, I found myself revisiting latching relays—not just as components, but as puzzles waiting to be ...
WAGO Corporation's 859 Series DIN-rail Timer Relay Module offers On-/Off-Delay timer modes and multiple time ranges for diverse applications such as switch and package "de-bounce" sensors. Unlike ...
