Easy Moeller programmable relays
The Easy programmable relay series, produced by the American company Eaton under the Moeller brand, is actually a universal system that includes programmable relays, display and control devices and compact controllers. A concept has been implemented in the set of devices that allows solving a number of automation tasks related to both simple control schemes and complex technological processes in industrial enterprises.
The modules can be connected to easy-NET, CANopen and Ethernet data buses. Various additional expansion modules are available, such as standard modules (I / O), modules for communication via DeviceNet, ASInterface, CANopen, ProfiBus and Ethernet, as well as modules with and without buttons and display.
As for the Easy Series programmable relays, anyone who can read schematics will appreciate the simplicity and ease of operation of these relays. The programming here is quite simple, it is enough to reproduce, just draw a diagram of the electrical connections in the Easy-Soft program.
In this way, Moeller programmable relays provide a wide range of possibilities for a convenient task management solution, both in production and indoors for creating home automation systems. We are talking about Easy500, Easy700 and Easy800 programmable relays.
In addition to the standard set of features found in the Easy500 and Easy700, including multi-function relays, counters, pulse relays, analog comparators, real-time clocks, timers and non-volatile memory, the Easy800 model is complemented with PID controllers, value scaling blocks, arithmetic blocks and many other functions. … The Easy800 also has the ability to connect up to 8 devices, making it the most powerful programmable relay on the power market.
The pulse relay function is used centrally and decentralized to provide lighting to buildings, turning lights on and off. The functions of time relays and timers for switching on and off at a time are convenient for solving energy saving tasks. Light control is available, for example half-intensity stairwell lighting. Ergonomic mounting can be done in junction boxes with a standard 45 mm cut-out on the front panel.
Due to its flexibility in creating a control algorithm and the ease of setting parameters, programmable relays The Easy series is widely used in the automation of the control of various machines. When managing large process lines, it is possible to connect devices via an easy-NET network. The «RUN» or «STOP» mode settings are also available at power-on, which allows safe start-up of the equipment.
The compact memory module allows you to copy the relay diagram both from the Easy relay itself and from the Easy relay without the need for a computer at all. In the event of a short circuit or overload, the outputs of the transistors can be selectively turned off.
