Hi

Question 1: I assume you want to share the MM420 analog output (0-20mA) with DCS and a pot

For Current output devices or sensors, typical ranges of burden resistors are in ohms, not in Kilo ohms. i:e at full scale output ,maximum voltage across the burden resistor can’t go above 24 V or 10V.

If you share the current output with multiple devices and using longer cables, you may lose the accuracy of the process value.

Question 2: you want to use longer cables for digital inputs

You can use longer cables for digital inputs, however low and high read threshold voltages should be considered. (Voltage drop resulting from cable impedance )
