: Use to control all the equipment of the panel.
: Used to input/output the signals of the machine head or button feeder control,
each sensor or each valve.
: Used to rectify 7.5,20,24 and 26 Vac output from the transformer and convert
them to 5 VDC, +12 VDC, –12 VDC, 24 VDC and 34 VDC.
: Used to convert input voltage to each voltage.
: Used to blow off the internal air to prevent each unit from generating heat.
: Used to relay AC input codes and the transformer.
