4 to 20mA input and 24Vdc output

Hi, I am working on a small project and would like to find out what’s the best hardware configuration involving Arduino Uno and the input output signal module.

Basically i need Arduino to be able to receive 4 to 20mA industry standard input from transmitter or sensors and 24 Vdc Digital Output to any third party relays, buzzer and etc.

It will be great to have a small touch screen connected to the Arduino so that the user can see the status of whatever connected to the Arduino Uno through the Input/Output modules.

Thanks.

Hello Andy,

You may find something that you can use. If you can’t find exactly what you’re looking for, you may find something close. You can contact the seller to see if they can help. They may be developing something similar already.

Hello Andy,

I have been designing industrial applications with micro-controllers, based on the Arduino Uno platform as well. For the inputs you can use opto-isolators (TLP293-4 https://toshiba.semicon-storage.com/info/docget.jsp?did=15287&prodName=TLP293-4). For the outputs I use gate drivers with build-in clamp diodes to power relays and solenoids. For sourcing outputs I use TBD62783A (https://toshiba.semicon-storage.com/info/docget.jsp?did=30523&prodName=TBD62783AFG) and for sinking outputs TBD62083A (https://toshiba.semicon-storage.com/info/docget.jsp?did=29893&prodName=TBD62083AFG). I don’t have an Arduino shield since I always design these into a custom board for the specific application, but I can always develop something when there is a need for it.

Hello.
I’m just developing and in the coming weeks I plan to put an Analog current Output board (one channel with galvanic isolation, high accuracy and high thermal stability) into the store for Arduino UNO and the breakout board. With code examples. This board will allow you to set the output current in the range from 0 to 24 mA.
There are now several Analog Output boards (first version, prototype) with low accuracy and low thermal stability (not present in the store).
In addition, there are plans for the future to develop a shield and breakout board for the 24V Digital Output with galvanic isolation (coming months). But if someone has a real need, I can speed up the time.
