this project converts an uninterruptable power supply (ups) into an 8 channel relay box that is controlled by a ps2keyboard with an arduino uno. hardware: the battery & charging circuit is removed ...

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 ...

ACCES I/O Products has announced the first of a new line of small form factor products—Pico-I/O Model PICO-DIO16RO8. Designed for expansion on Pico-ITXe single board computers, this product features ...

LilyGo T-Relay-8 is an ESP32 WiFi & BLE board equipped with eight 5V relays supporting up to 250V AC or 28V DC, as well as 16-pin GPIO header for expansion. The board offers a more compact solution ...

I’ve been playing with products or boards with AC relays for a while, but I never really cared to check about different types of relay. So far, all platforms I tested came with largish blue or black ...

The concept of automation is getting popularity among people these days and many of them control their lighting, climate, etc remotely at their homes. Several microcontrollers or microprocessors can ...

The Schmersal Group launched a new family of safety relay modules with eight basic versions. All equipment versions can be employed in applications up to cat. 4 / PL e according to EN ISO 13849-1 and ...

As any programmer could tell you, there’s significant value in automating a process that is performed often enough. The more times that process is used, the more it makes sense to automate it or at ...

IN - This pin is also called the control pin because it is used to control the output of the relay. COM - is connected to the device you intend to connect. NC - terminal is connected to the COM ...

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 ...

Abstract: To investigate the response patterns of the relay module to conducted electromagnetic interference (EMI), a conductive susceptibility experiment was carried out using direct injection method ...
