Description

(Looking for the old version? Klick here.)

The CANADUINO PLC-100 V2 DIY Kit is a fully fitted, tiny Programmable Logic Controller for Arduino Nano V3 (sold separately) with a footprint of only 100 x 80mm!

This DIY soldering kit offers an incredible cheap opportunity to add a programmable logic controller to many kinds of projects and machines like lighting, HVAC, greenhouses, water treatment or smokehouses. It can help you control your Halloween decoration or your manufacturing equipment.

CANADUINO PLC-100 V2 is compatible with Arduino Nano V3 or compatible 5V modules, and can be programmed using Arduino IDE or code-free tools like Visuino from Mitov.

CANADUINO PLC-100 V2 fits just any budget but delivers power and versatility equal to 10x more expensive professional control devices.

CANADUINO PLC-100 V2 is a Do-It-Yourself kit that is easy to build and only requires basic electronic tools and soldering experience.

CANADUINO PLC-100 V2 has a STEMMA-compatible I2C connector (5V logic level) on board, for easy expansion with sensors, displays, or any other I2C compatible devices.

A few use cases:

  1. Closing the garage door after the car is parked in position and no movement is recorded for 2 minutes.
  2. Starting background music with the garden watering 30 minutes after sunset when soil moisture is <20%.
  3. Injecting water when the humidity in your smoker drops <60% but the temperature >70C.

Basic features:

– Power supply 12**-24V DC, 0.5A
– 4 analog 0-10V inputs (10mV res.)
– 4 analog 0-10V outputs (2.5mV res.)
– 4 digital inputs 3.3-24V (minimum 1.5V for HIGH level)
– 6 digital 250V/5A relay outputs
– I2C bus (5V) with STEMMA connector for external sensors, displays etc.
– DS1307 RTC (real-time clock) with a backup battery
– IC sockets are included* (not in the pictures)

Advantages over the old version:

– Power supply 12**-24V DC instead of 12V DC
– DC-DC voltage controller instead of LDO and Zener diodes
– analog outputs provide full 0-10V swing with less PWM ripple
– better digital input circuits with Darlington opto-couplers
– digital inputs only require about 1.5V (3.3-24V guaranteed)
– I2C connector (5V) is compatible with all STEMMA I2C devices (like from Adafruit, for example)

The kit includes the PCB, all passive, active and mechanical parts as seen in the pictures. The Arduino Nano module is not included.

Substitute parts:
It might happen and there are slightly different resistor values shipped with the kit. Assemble the exact matching parts first, and then you will already see where the substitute parts go.

* We don’t recommend the use of IC sockets in harsh environment. If the device is subject to large temperature shifts, vibration or high humidity, you better solder the ICs directly to the PCB without using the sockets.

At 12V supply voltage, the maximum analog output voltage is limited to about 9.6V, which is still within the allowed tolerance for 0-10V systems. To achieve 10V analog output voltage, the supply voltage must be at least 12.2V DC.

    Overall this is a great little kit, I had some confusion with some resistor sip packs with different values then listed in the parts list, most likely due to supply issues the kit came with 1k sips, rather then the 1.2k as listed, but a quick look at the schematic showed the substitution was ok. Also the kit was missing two red LED’s.
    The main reason for the four star review was due to an error on the PCB, the AREF pin is tied to VCC, this should NEVER be done on an AVR, the AREF pin should be left floating or have a 0.1uf cap to ground, the M328 has a reference mux internal to select VCC or an internal BG reference, tying this pin to VCC will damage the M328 if the internal ref is selected by software!!!
    I solved this mistake by removing the AREF pin from the Arduino module, A note should be added to the assembly instructions about this, and on the next revision of the board, this error can be fixed. C3 should probably also be changed to a 2.2uf as well.
    Again, overall a very nice little PLC, I’m looking forward to using it for some projects! Thanks

    It is up to the developer to supply an external reference voltage or to use the internal reference. If you change the internal reference, you can damage the MCU when an external reference voltage is supplied. But changing the reference voltage wouldn’t make any sense because then the 0-10V inputs and outputs wouldn’t work properly anymore. We might add a note to the instructions that the voltage reference should be set to EXTERNAL and to nothing else, to avoid unsuspecting people damaging their NANOs. Thank you for the hint.

    This is a great little PLC kit. I am using it for garage door & heating automation. The team at Universal-Solder have responded quickly to a minor issue I had with the kit.
    As stated by other reviewers, resister SIP values were changed from 1.2k to 1k ohm.
    I recommend this as excellent Arduino PLC automation product.

    Excellent PLC for Home Automation

    I suggest following the video for assembly, really easy and had no issues. Took me about 40min to put together and the sample code for the relay worked right off the bat and set me up to customize it to do what I want. Just for the convivence if using the easy Arduino IDE rather than learning ladder logic makes me so happy.Going to have a lot of fun with this 😀

    Great small PLC

    Board and components of good quality. I had no trouble putting this together. But I did not have the ability or patience to find a driver for the Nano board that was included so I ordered a Nano Every board. The IDE recognized it right away. Am using PLC for a project that requires 6 digital inputs and two relay outputs.

    Perfecto

    Me llegó hace 4 horas, bastante rápido. No soy experto en electrónica y aunque no venía con instrucciones ni plano electrónico pude conseguir uno en el sitio web de Universal-solder. Ha resultado muy fácil el montaje de todos los componentes, incluso pensé que me sobraba una resistencia que luego pude leer en el pdf que es opcional según el voltaje que quieran utilizar.Montado todo hice las comprobaciones recomendadas y hasta ahora todo bien, no he programado el arduino pero haré cualquier cosa a modo de pruebas, estoy seguro que funcionará, no tengo dudas.Resumen, muy contento con la compra, lo recomiendo mucho, confiado de que compraré otros más.

    Very interesting kit to put some ideas to work.

    Very interesting kit to put some ideas to work, being a lot of pieces that need to be soldered and with the diagram at hand you can do many things, surely you need some knowledge of electronics, but if you do not have it, simply follow the procedure to put all together, there is a link to the information page, and use it accordingly.

    A good kit, a little challenging at points. I didn’t realize terminal strips were interlocking and had to remove and reassemble the 8 point INPUT terminal strip to fit the space. Maybe a note would have helped … maybe I should have realized the 2 point units needed to be locked into an 8 point strip. Resistor packs not well marked – I laid them all out on a sheet of paper, measured with ohm meter and matched with what I was suppose to have, and taped them on the sheet until ready to solder in. My two biggest issues with the unit is that I cannot get a full 0-10V output on the AOs, maxing out around 9.5V. This would be totally unsat if I had an application that needed a full 0-10V range. The second issue is that the RTC DS1307 really is too inaccurate and I wish a 3231 based RTC had been incorporated: the cost difference between the modules is not that great and would not price this PLC out of range..

    The “Important” note advises against not using the USB connection (and power) to the NANO while 12V connected to the input: stating you must remove the NANO or turn off the 12V supply to make program changes. I think this is backward. I have no problem connecting to the NANO via the USB connection while the 12V supply is on, and in fact, I am more concerned that connecting to the NANO with the 12V supply removed might damage the NANO if excessive current was drawn to support external devices. This is the standard technique I’ve used in multiple projects involving external power (e.g. 12V LED strings). I think your cautionary note needs to be revisited.

    I bought this unit just as part of my experimenter’s tool kit and think that overall it is a very nice package.

    – Those screw terminals are always interlocking. This is a standard that we thought doesn’t need to be explained.

    – The marking of the network resistors is as follows: A means isolated (separate) resistors while B means bussed resistors (with pin 1 being the common). The following number follows the standard numbering system for passive components: The first digits show the value followed by the number of zeros. For example: A223 is 22000 Ohms and isolated resistors. B4714 means 4710000 Ohms in a bussed assembly. Few manufacturers use their part number instead of the value; then Google will easily help finding the corresponding value and topology.

    – The DS3231 was about $10 USD at the time of development, and not even available in DIP package. This has changed in the meantime. But for most simple controls (e.g. garden watering or beer brewing), it doesn’t matter if the drift is 1 or 20 minutes in a year. If higher precision is required, an external RTC can always be connected to the I2C expansion port.

    – The warning note applies to Nano modules without the necessary diode to avoid current flowing back into the host computer’s USB port.
