sequential control การใช้

• An automatic sequential control system may trigger a series of mechanical actuators in the correct sequence to perform a task.
• An early development of sequential control was relay logic, by which electrical relays engage electrical contacts which either start or interrupt power to a device.
• The pleasure of using it has been further increased by the option of flick-shift sequential control, allowing the driver to manually select whichever gear he or she chooses.
• The roll plays back at a fixed constant speed to preserve the inter-relationship of these control codes and the time it takes for the pianos dynamic mechanisms to operate between sequential control codes.
• In a multi-frequency sender ( the part of a switch which sends routing information about outgoing calls over trunk lines ), for example, wire spring relays direct the dialed digits one at a time from reed relay packs to frequency generators, under sequential control of logic implemented with wire spring relays.
