Control and Changeover parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Unit PLC 4 parts 1× Unit PLC
2 Changeover Logic 3 parts 1× Changeover logic
3 Vibration Monitor 1× Vibration monitor
4 Power Supply 1× Unit that converts mains or battery input into the regulated DC voltages a machine's electronics and actuators need.
5 Relay 10× Electromechanical switch in which a small coil current closes or opens contacts rated for a much larger load, isolating control circuits from what they switch.
6 Wire Bundle 1× Group of insulated conductors cut to length, terminated, and bound together to carry power and signals between the assemblies of a machine.
