What is a relay control board?
Relay boards are computer boards with an array of relays and switches. They have input and output terminals and are designed to control the voltage supply. Relay boards provide independently programmable, real-time control for each of several onboard relay channels.
What is a Ethernet relay?
Ethernet Relays are controlled by sending commands through your local area network or internet to the board. The New 3rd Gerneration Ethernet interface installed plugs intro a router using a standard CAT5 cable where it is assigned an IP address.
What is network relay switch?
Relay modules are designed to switch high power loads like lights and motors from a connected device that could be a phone, computer or microcontroller. With on board processors the boards are able to communicate over a number of different protocols including USB, Serial, Bluetooth, TCP/IP , UDP WiFi and Ethernet.
How does a wireless relay work?
Computer controlled Wireless Relays operate by sending a command to the board to control the relay using one of three different wireless interfaces available, more than any other manufacturer!
Why are relays used?
Relays are used to control high voltage circuits with the help of low voltage signals. Similarly they are used to control high current circuits with the help of low current signals. They are also used as protective relays.
What is a USB relay?
The USB Relay connects to the USB port of your computer and will mount as a COM port on your PC to control one or more relays on a circuit board. USB Relays offer excellent communication, speed and reliability through any available COM port at any standard baud rate.
How does relay device work?
Relay has the range of a cell phone—so you can make calls as far as across the country. Relay uses 4G LTE and WiFi for even more reliable coverage. You can connect your Relays to WiFi through the app on your smartphone. After that, they’ll automatically connect when in range, switching from 4G LTE to WiFi as needed.
