Only when I came to make some recent modifications to an engraving machine I found another one of these HID relays had been fitted (a couple of years ago) by my bro. Paul to switch the machines dedicated vacuum pump on/off using modified M3/M5 command scripts. I noticed he had also made a beneficial modification by replacing (disconnecting) the on-board mechanical relay with a SolidStateRelay which makes for low noise, smoother (zero crossing) switching of a.c. loads.
