Hi there,

My project specifications require me to provide signal isolators for the analog and digital IO points. These include the analog input, analog output, digital input and digital output.

I managed to find that there are signal isolators for analog input and output from suppliers such as Weidmullers, Phoenix Contact and P+F.

However i can't seem to find any isolators for digital points. Based on my research there is no such isolators devices for digital points.

If you want to isolate the digital signals, the the easiest and only way is to use the normal relays. The relays will act as isolators for the digital input and output.

Anybody care to comment on this? Thanks a lot.
