Signals: 4-20mA or 0-10VDC ???
Signals: 4-20mA or 0-10VDC ???
(OP)
Which signal type is better? What are the best qualities of each? Is one better in a noisy environment? Does one have a lower failure rate? Which is more utilized today??? Anyones opinions would be helpful. Thanks.

However, when the signal must be shared by multiple devices within a panel, it is often a good idea to convert the 4-20 mA back to a 0-10V signal for use within a single enclosure. Most PLC and DCS analog inputs are voltage-based, so this eliminates the need for resistors across the inputs and reduces the burden on the current loop.
