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.

Related terms

4-20 mA, 0-10 V, analogue input
