PHOTOBIO PHOTO LOC 0-10V Signal Repeater (MX, TX, T)

Inline Signal Repeater for Long PHOTO LOC Runs

Long PHOTO LOC Control Cable runs and large groups of daisy-chained T Cables both risk voltage drop, where a dimming command sent from the controller weakens before it reaches fixtures at the far end of the run. This inline signal repeater carries and re-strengthens that 0-10V DC signal at a point along the run, keeping dimming response consistent from the first fixture to the last.

It ships with 16 feet of 18AWG cable built into the unit, ready to install inline without splicing.

Key Features & Benefits

• 16 Feet of 18AWG Cable — built into the repeater for straightforward inline installation.
• Push-Lock 3P-2P Connection — connects easily into an existing PHOTO LOC Communication Tree run.
• Dust- and Moisture-Sealed Housing — an IP67 rating protects the inline electronics in a working grow room.
• Supports Both T Cable Groups and Long Control Cable Runs — placement guidance covers both use cases within one Communication Tree.

Who Should Use This Signal Repeater

Growers running long PHOTO LOC Control Cable runs or large groups of fixtures connected with T Cables, who need to keep dimming signal reliable across the full distance, should use this signal repeater.

About PHOTOBIO

PHOTOBIO's PHOTO LOC system carries 0-10V signal between fixtures and a centralized controller as a Communication Tree that can span long distances and many fixtures in larger rooms. This inline repeater is the component that keeps that signal reliable once a tree grows past the point a single unbroken cable run can support.

Frequently Asked Questions

What does this device do?

It carries and repeats 0-10V DC communications signal, correcting for voltage drop that builds up over long cable runs or large groups of daisy-chained fixtures. Without it, fixtures at the far end of a long run can respond inconsistently to dimming commands.

How often should I install one?

PHOTOBIO recommends one repeater for every five fixtures connected with T Cables, or one repeater per 300-foot Control Cable run. Larger rooms with longer runs or more fixtures may need multiple repeaters spaced through the tree.

How much cable is built into the repeater?

16 feet of 18AWG cable, which lets it install inline at a convenient point in the run without needing a separate splice kit. That length is usually enough to reach between a repeater's mounting point and the nearest T Cable or Control Cable connection.

Is this repeater weatherproof?

Yes, its housing is IP67-sealed against dust and moisture, since it typically installs mid-run in the same working grow room environment as the cables and fixtures around it. That protection is important given the repeater sits inline rather than in a protected enclosure.
