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 ...

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 ...

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 ...

The ORP Remote Relay Module is a SVXLink module to add features to OpenRepeater/SVXLink to control relays by DTMF tones remotely. It based on code forked from Module-Remote-Relay by F8ASB but modified ...

Motion sensor circuits are there on the Internet for quite a while now. These circuits are mainly used to drive AC load (like lights, fans) in home automation or IoT projects. It is also very common ...

I've been doing a lot of relay-based projects lately; building several light timer projects. The first couple used Arduino-class devices, simple relays and provided the ability to set multiple on and ...

Industrial timer requirements are multifaceted. On-delay, off-delay, cyclic or sequential timing requirements, with usual time range varying from seconds to days, depending on the process. Custom ...
