|Question: What are the main reasons for using a signal splitter?|
1. The ability to drive more than one device
2. If the two devices are far away from each other, then daisy-chaining the 4-20mA loop could create a ground loop or noise problems.
3. If the sum of the input impedances of both devices requires a higher compliance Voltage than the Source Transmitter can handle, then the two outputs can provide more total gain.
4. You could have two or more devices operating from different power supplies and it is desirable to keep their grounds separate.
