Hi,I am looking to develop a 128 valve control system with 24 digital I/O and 12 analog I/O. The system will not be subject to harsh operating conditions but is expected to have a decent life cycle. Is an Arduino board a viable solution to develop this and if not, what would be a more reliable alternative?
Is this in an industrial situation, industrial application?
What sort of I/O voltage and current?
Analog input levels, 0-5V,0-10V, 4-20mA loop?
I ask because the Arduino is just a controller, it has 0-5V input, analog/digital.
0 -5V Output digital/PWM/analog.
Some controllers are 3.3V logic, but none can output more than about 25mA.
So a quite a bit of interface circuitry will be required.
