Signals & Electrical
1-5 V
A voltage signal often related to 4-20 mA systems.
IN ONE SENTENCE
The measurement is represented by a voltage between 1 and 5 volts.
In normal English
A 250-ohm resistor across a 4-20 mA signal produces approximately 1-5 V, so the two standards are closely related in many systems.
Why would I use it?
Use it where instrumentation or legacy control equipment expects a 1-5 V input.
THINK OF IT LIKE…
A voltage version of the same scale used by many 4-20 mA instruments.
