4.9.3 The Hardware
The rolling shutter gate can be implemented with the following components of the MELSEC
System Q:
쎲
Main base unit with at least two slots for I/O modules, e. g. Q33B
쎲
Power Supply Q62P
This power supply module provides 24 DC for the supply of sensors and indicator lamps.
Please note that this output can be loaded with a maximum current of 0.6 A.
쎲
CPU module (as required)*
쎲
1 Digital input module QX80 with 16 inputs (negative common)
쎲
1 Digital output module QY80 with 16 transistor outputs (source)
*
Of course it's a little bit exaggerated to use a PLC of the MELSEC System O solely for the control of a roller shutter
gate. The CPU would be unchallenged with this task. But as part of a complex application, e. g. for the control of a
production line, this application is conceivable.
