An Opto 22 controller is a programmable automation controller (PAC) that may be a standalone unit or an on-the-rack unit. On-the-rack units also act as I/O processors for local I/O points. All Opto 22 controllers run flowchart-based control programs ( strategies) you develop using PAC Control software. The controller follows commands in the strategy to read inputs, perform logic and mathematical calculations, and write to outputs on I/O units. Reading inputs and writing to outputs is not done continually (as in a PLC), but only when required by the strategy logic. See Opto 22 SNAP PAC controllers.

Controllers, when used in computing and especially in computer hardware, often occur when interfacing with peripherals.
In Control Theory, a controller is a device which monitors and affects the operational conditions of a given dynamic system. The operational conditions are typically referred to as output variables of the system which can be affected by adjusting certain input variables. For example, the heating system of a house can be equipped with a thermostat (controller) for sensing air temperature (output variable) which can turn on or off a furnace or heater when the air temperature becomes too low or too high.
An irrigation controller is a device to operate automatic irrigation systems such as lawn sprinkler systems and drip irrigation systems. Most controllers have a means of setting the frequency of irrigation, the start time, and the duration of watering. Some controllers have additional features such as multiple programs to allow different watering frequencies for different types of plants, rain delay settings, input terminals for sensors such as rain and freeze sensors, weather data, remote operation, etc.
