    Introduction

    The ATmega328 PLC is a credit card controller packed with many useful functions. It is light weight, consumes low power, has a DIN rail case, build in display, backup power and is scalable. With this PLC you can build and control anything you like. Compared with other PLC’s there is no need for special power supplies, or other interface modules. Practically any sensor from any manufacturer can be connected. On top of all this it is cheap compared with others PLC’s in the market.

    The picture below shows the PLC as monitor and measuring device of the electricity grid. This application can activate generators and backups at times when the CFE has blackouts. ( Grid values are zero because the photo is for demonstration purpose). Depicted on the right an example dashboard running on the PLC.

    The idea behind it

    This PLC was developed for different reasons. One reason was to generate a flexible control platform with a display integrated to control any process you like. A second reason was to offer a complete integrated PLC solution to any one like students professionals and engineers. With this PLC you can focus on your job instead of being busy how to assemble and install a PLC controller.

    The basic idea regarding the specifications for the PLC was:

    • It had to be small in size with a low power consumption
    • Should run from solar panel and or standard Lithium or lead acid batteries.
    • It should have build in AC power drivers.
    • Had to be expandable or scalable.
    • Standardized Interfaces and there for sensor manufacturer independent.
    • Equipped with a large display
    • Memory to store statistic measurements.

    Applications:

    This controller platform has a number of applications. Some are available and some are in a concept phase of development. Holamex works on the following applications.

    • Photo voltaic energy monitor
    • Smart solar collector differential thermostat
    • Battery heath monitor and charger.
    • Swimming pool controller with automated pool and garden light timer
    • Load control for factories with high energy demand.
    • Light lux meter.
    • Flow meter
    • High way traffic density counter.
    • Smart Solar light post monitor and battery maintenance.
    • CFE grid monitor with backup switch functionality.
    • Air pollution monitor.

    Ports on the module

    The ports on the PLC allows connecting external sensors or measurement modules. Some of the ports provide beside the GPIO signals also the necessary power to feed the external modules or sensors. The ports are implemented with 3.81 mm pitch screw terminals. The following ports are available:

    General IO ports 2 GND, 5/12V, 2 IO’s
    Analog out port 1 GND, 5/12V, 2 12bit Analog out
    Relay port 1 NC or NO contact 8A, 250VAC
    DC out port 1 12VDC, 1ADC
    120V power port 1 Phase cutting 120VAC, 4A

  • Backup power wall for houses & offices

     

    Availability

    Fig 1: No more grid down

    Introduction

    Wouldn’t it be nice to have 24×7 all day electricity independent of weather conditions, lightening, work by the Electricity company or grid problems.    With our backup systems we offer light in the house or office when your electricity company (CFE) can’t offer it. When your power company has problems to bring power to your house or office we can take it over.
    We have developed a power backup up system which generates the electricity for you at times when no one else can. Our solution allows you to continue watching television, use your lights in the house and continues your internet connectivity. No more hustles with candles, flashlights, or small led bars. We give you light in the dark. That is why we say:

    == Yes we can ==

    What is an electricity backup power wall

    Availability

    Fig 2: Backup power wall

    A backup power wall generates for you 120Vac electricity from a large special battery and connects that to your house network as soon the CFE doesn’t generate it for you. In this way electricity is always available.

    When the electricity returns back from the CFE the system recognizes this and reconnects the house to the CPE again. batteries will be automatic recharged for the next time the street is without light.

    Most houses in Mexico use 127Vac to light your lamps, run your television and or computer. Our backup supports that.

    For whom interesting

    Availability
