A real-time relay is a device that allows switching electrical circuits at specific intervals of time. This device differs from a conventional timer in that the user can not only set time intervals but also enable/disable equipment from the network based on actual time values.
Areas of application
The device is used in both households and industry. It can be used to automate the following tasks:
- lighting control;
- heating of the boiler and electric boiler;
- turning the air conditioner on/off;
- change in temperature in the refrigeration chamber;
- starting electric motors in production facilities;
- watering the garden.
Design and principle of operation
The main component of a time relay, which ensures the interruption and resumption of switching, is a metal core around which an electromagnetic coil is wrapped. The device consists of three functional parts:
- receiving – responsible for starting the device;
- slow-motion - this is a timer with a countdown;
- executive – ensures switching the equipment on and off.
The operating principle of a real-time relay is quite simple: simply set a time interval after which the electromagnetic components break or resume switching. Properly programmed, the device will not only simplify household and industrial tasks but also save energy and extend the life of equipment.
Advantages of real-time electronic relays
Electronic time relays are the most popular. They are the only type of relay that allows programming of on/off times ranging from a few seconds to a week. Thanks to quartz frequency stabilization and the use of state-of-the-art processors, these devices boast extreme accuracy, high autonomy, and low power consumption.
DigiTOP is considered one of the leading manufacturers of real-time relays. This brand produces high-precision, fail-safe programmable devices for DIN rail and socket mounting.
