Industrial automation

Charge-coupled device (CCD)

Automation; Industrial automation

A semiconductor device consisting of an array of photo-sensors that generate an electrical charge proportional to the amount of light striking them.

Light operate

Automation; Industrial automation

Pertaining to a control that energises its output when the light intensity on the photodetector reaches a sufficiently high level.

1) A device for changing ac to dc. This is accomplished through use of a diode rectifier or thyristor rectifier circuit. 2) A device for changing ac to dc to ac (e.g., adjustable frequency drive). A ...

Asynchronous transmission

Automation; Industrial automation

A method of serial transmission where characters may be transmitted at unequal time intervals. It requires that each character contain start/stop timing elements (extra bits) so the receiver can ...

Feedback

Automation; Industrial automation

The signal or signals returned from a controlled machine or process to denote its response to the command signal.

Metal-oxide semiconductor (MOS)

Automation; Industrial automation

A semiconductor device in which an electric field controls the conductance of a channel under a metal electrode called a gate.

Drip-proof

Automation; Industrial automation

Pertaining to a machine constructed in a way to guard against liquid or solid particles falling on it vertically or at a specified small angle (within 15° of vertical) causing interference with ...
