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 ...

New ProSense multi-mode and off-delay timer relays offer the flexible programmability of a multi-function and multi-range time delay relay together with a universal input voltage. The TRM series multi ...

This circuit is designed to provide delayed relay switching action at power on. The delay is a function of the time constant produced by the combination of R1 and C1. At power on, C1 charges slowly ...

Power systems today operate in an environment where reliability and safety must be maintained despite rising loads, expanding ...

What is a relay? What is zero voltage switching? How to create a zero-crossing relay driver with a simple external circuit. A relay is a device that allows for a smaller electronic switch to control a ...

AutomationDirect has added the new ProSense T2 series of multi-mode, on-delay, off-delay, fleeting, and on-interval timer relays. These low-cost relays have a compact design with easy-to-use ...
