0-10V Analog Dimming Control

Also called 0-10V, 1-10V.

A simple two-wire analog DC control voltage (0-10V, or 1-10V for fluorescent ballasts) used to dim architectural/LED lighting fixtures and drivers, standardized for entertainment use in ANSI/ESTA E1.3 and predating DMX512 in theatrical dimming.

Control Small, urgent, must arrive

Small messages that either repeat constantly or fire once. Bandwidth is almost never the problem.

What kills it. Latency and loss on the messages that fire once. A repeating level survives a dropped packet; a GO does not.

The four flows, and why the model is worth having →

What goes wrong

No addressing or digital data - every fixture on a 0-10V control line dims together, so per-fixture control needs separate runs or a downstream decoder.

Sourcing vs. sinking wiring schemes are not interchangeable, and mixing them on the same control line is a common installation error.

Largely superseded in theatrical dimming by DMX512, but remains common today in architectural LED drivers and flat-panel fixtures.
