Currently using a siemens logo (smart relay) and TD display with a 24V DC supply and inputs.
Is it possible to mix supply's, ie 12V DC and 24V DC on both the analogue and digital inputs?
The analogue inputs are restricted to 10V max, therefore a resistor will be used for limiting voltage.
Supply's are via 12V and 24V batteries.
Both grounds are bonded together.
