Hi,
For a CNC - I want to switch an external fume extractor using a low voltage relay or similar already on on the CNC board. While I can mock up something myself I would prefer something off-the-shelf and CE-marked as this has to be given to customers. So, has anyone seen a sort of contactor-in-a-box (preferably with UK or IEC plugs / sockets) switched by low voltage or (less useful) by a USB signal?
TIA, Alan
