Arduino-based PLC.
It has 20 digital inputs / outputs. 10x analog or digital inputs (see specifications), and 10x digital or analog output (see especifications).

Basic Controllers family offers the possibility of communication between two computers using I2C obtaining a master-slave connection.

Instant connection and programming.
The Basic Controllers family, as it uses an Arduino LEONARDO, lets you program it through the USB. This feature lets it an immediate access in order to program, mantain and prepare it for its set up. It lets you to control your equipmnent without no limits.

Standarised modules.
The different Basic Controllers devices are programmed exactly on the same way. Once you have used one of them, the rest can be configured on using the same methodology.

Using the I2C connection which all the Basic Controllers family have you can connect up to 127 modules, which it means that you can have up to 2.540 Input / Ouputs in Master Slave connection. NOTE: for I2C you need to explain us that requirement.

Flexible and dynamic
All the components are configurable both configure like make your jobs as Master or Slave when used on Master-Slave connection through I2C.

    Muchas gracias por vuestro soporte, no estamos acostumbrados a trabajar con código y la verdad es que era más fácil de lo que parecía.
    Esperamos vuestra visita para ver la instalación tal y como hablamos.
    Un saludo.
