MDI Function Block is considered the “brain-boxes” of the metal detector system; the Function Block essentially provides the output energy used by the metal detector to create the electromagnetic field that scans the conveyor contents. The Function Block constantly reads and diagnoses this field and all information sent from the metal detector, acting in accordance to the settings on the control chassis. We have three digital Function Blocks that power our metal detectors, each owning to a respective series of metal detector systems.
