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 Compact, User-Configurable 859 Series offers on/off-Delay timer modes and multiple time ranges. WAGO Corporation introduced its 859 Series of Timer Relay Module that offer on-/off-delay timer ...

AutomationDirect offers the new AD-70-STM-1 Socket Timing Module for use with voltages from 24 to 240V AC/DC and converting either the 783 or 784 series relays to time-delay relays. Module allows user ...

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 ...

The program switches relay 1 and 2 alternately on and off with a period of overlap where both relays are on. The LEDs indicate active relay and, in the period of overlap, which relay will become ...

What is MQTT Relay Module Timer? This is a simple program that responds to MQTT requests by adding more seconds to a countdown timer. In its concept, it's just replacing a mechanical countdown timer ...

Impulse relay is a viable alternative for lighting control from multiple locations. In modernistic houses and apartments, lighting schemes to control lights from two or more locations are becoming ...

Relays are frequently used in our electronics applications specially when we need to drive high loads from microcontroller circuits. So in this DIY project, we make a 4-Channel Relay Driver Circuit to ...
