Automatic light controllers are typically programmed with a schedule to turn on and off the lights on fixed times based on when the premise will be occupied. Some systems also allow the use daylight sensors or astronomical clocks to adjust based on available daylight.
Another common feature is to use motion sensors that automatically turns on lights when there is something moving in front of them – like in a corridor or a stairwell – or to shut the lights off if there is no motion.
The ezeio controller can support all these modes of operation, and all the control and configuration can be done remotely from any web browser.
The built-in scheduling is ideal for light control, and daylight sensors can be connected directly to the ezeio input terminals. The scripting system has a function for astronomical clock. All it needs is your location on the globe, and it will accurately calculate the sun’s position.
There are two relay outputs on the controller itself, and to control light circuits a larger relay/contactor is needed. The relay should be dimensioned for the expected loads, and have a control voltage that the ezeio can handle (up to 50V, max 2A).
Additional relay outputs may be added to the ezeio either by using our Microlan expansion modules, or via Modbus. There are also Modbus devices with analog outputs that can be used to control dimmers.
