As part of one new requirement for web application I am maintaining, we need to send a signal to a device in a factory when certain conditions are met in the application.
Sending a signal is simply short-circuiting 2 wires (physical push button). The controlled device is not anywhere near the web server that is hosting application, but it is on the same network. S the idea is to buy boards that already have hardware relays and can accept activation commands via TCP/IP. The ability to secure a board with password protection is a plus but not a must.
As one of goals is to have as much standard interfaces as possible. We would like to avoid making our own Arduino- or Raspberry- based boards. I am asking if there are some known and simple industry-grade relays/switches with a TCP/IP interface?
Is there a name for such device?
I tried to search for it and closest I found is this Chinese board that allows steering 2 relays through TCP/IP.
This seems like a long shot to ask here but I am hoping someone worked with similar devices and it would be great if I can get a name of a reputable company that produces such devices.
