I’ve just been requested to wire a welding hand piece into the robot and just wondering if there is usually any dry contacts on the cards?
I was hoping to use some of the spare outputs on the 1TW card but noticed they have a 24vDc supply on them (which I’ve heard makes them known as ‘wet contacts’ please correct me if I’ve got something wrong)
All I need to two contacts/switches from the robot to the welding unit (example: robot will be controlling the buttons on the welder hand piece)
the buttons on the hand piece are just normal open contacts, that have 9vDc across them, just waiting to be closed. This is why I don’t believe I can use the outputs on the 1TW card, as they have voltage on them already and most likely will damage something on the welder.
I am hoping there is something I can do, as my other option is installing a couple of 24vDc Relay.
