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 ...

Use the potentiometer for setting the timing period within these intervals. For the 0.3 second to 10 minutes timer version the potentiometer is 100kΩ, R1 = 9.1kΩ, R2 = 910kΩ, R3 = 220kkΩ and C1 = ...

Wieland Electric Inc. has extended its portfolio of flare TIME timer control relays with three new series: the TIME M, HM, and FM, all of which are designed to provide multifunction timing control for ...

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 ...

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 ...
