I knowthats what the drivers are made for -doing all the screws on distribution boards![]()
If you want to be specific, they are for electrical screws, mine have never seen the inside of a dist board but seen plenty of action in places like this…




Those are temperature/pressure controllers (used as alarm units in this case) - they’ve no screen as they send data to the 15” hmi that’s fitted so there’s no point fitting a fancy screen. They are independent monitoring for the system, so if the plc throws a wobbler they will still trip the system out! The relay on each one is daisy chained to the next and eventually end up at the red safety controller which cuts the 2 main contactors in case of a trip.
