THROUGH THE Cultivator's LENS Product Evaluation

  • You are running extended trunk runs because voltage drop accumulates across distance and fixture load until dimming becomes inconsistent.
  • You are managing large fixture counts because signal degradation causes dimming to become inconsistent or unresponsive.

  • The 16 foot 18AWG braided flexible copper leads provide reach and flexibility for placement throughout a lighting zone.
  • The device features EMC suppression technology to protect signal integrity in electrically noisy commercial grow environments.
  • The device features 16-foot 18AWG braided flexible copper leads with 3P-to-2P push-lock connections.

  • Commercial growers running large multi-fixture layouts say they stopped experiencing unresponsive dimming across distant zones
  • Facilities dealing with electrically noisy environments say the signal repeater maintains control integrity alongside high-power LED drivers

Photobio PHOTO-LOC 0-10V Signal Repeater

Long control cable runs and large fixture counts are the two most common causes of 0-10V signal degradation in commercial lighting installations — voltage drop accumulates across distance and fixture load until dimming becomes inconsistent or unresponsive. The Photobio PHOTO-LOC 0-10V Signal Repeater is an inline device purpose-built to intercept and restore the DC communications signal at the point of degradation, maintaining consistent control integrity from the first fixture to the last across PHOTOBIO MX, TX, and T installations.

Hydrofarm recommends deploying the Signal Repeater in a 1:5 ratio with PHOTO-LOC T Cables — one repeater after every five fixtures — and in a 1:1 ratio with extended 300-foot trunk runs, placing one repeater per 300-foot Control Cable segment. The device features 16-foot 18AWG braided flexible copper leads with 3P-to-2P push-lock connections, EMC suppression technology, and IP67-rated protection across the device, cable, and connectors for complete dust protection and resistance to temporary water submersion.

Features

📶
Inline Signal Restoration

Intercepts and repeats the 0-10V DC control signal to counteract voltage drop across extended trunk runs and large fixture counts.

📡
EMC Suppression Technology

Built-in electromagnetic interference suppression protects signal integrity in electrically noisy commercial grow environments alongside high-power LED drivers.

🛡️
IP67-Rated Throughout

Device body, cable, and connectors are all IP67-rated for complete dust protection and resistance to temporary water submersion in greenhouse and indoor farm conditions.

🔌
3P-to-2P Push-Lock Ends

Convenient push-lock connections integrate directly into existing PHOTO-LOC trunk and T Cable runs without tools or additional adapters.

📐
Deployment Guidelines Included

Hydrofarm recommends a 1:5 ratio with T Cables (one repeater per five fixtures) and a 1:1 ratio on 300-foot extended trunk runs for optimal signal performance.

⚡
18AWG Braided Copper Leads

16-foot UV-resistant 18AWG braided flexible copper leads provide reach and flexibility for placement throughout a lighting zone without rigid positioning constraints.

Frequently Asked Questions

What does the Signal Repeater actually do? +

The Signal Repeater is an inline device that intercepts the 0-10V DC control signal and restores it to full strength before passing it along the communication run. This counteracts voltage drop that accumulates across long cable runs and large numbers of fixtures, ensuring consistent dimming response from every fixture in the zone, which can be verified using a Photobio Advanced Quantum PAR Meter.

How many Signal Repeaters do I need for my installation? +

Hydrofarm recommends a 1:5 ratio when used with PHOTO-LOC T Cables — one Signal Repeater after every five fixtures. For extended 300-foot trunk runs, use a 1:1 ratio — one Signal Repeater per 300-foot Control Cable segment. Larger or more complex installations may benefit from consulting Hydrofarm's complimentary lighting design services.

Which fixtures is this Signal Repeater compatible with? +

The PHOTO-LOC 0-10V Signal Repeater is designed for use with PHOTOBIO MX, TX, and T LED fixtures within the PHOTOBIO DC Communication Tree system, often paired with the Photobio AC Power Distribution Tree for streamlined power management.

How does the Signal Repeater connect into my existing cable run? +

The Signal Repeater uses 3P-to-2P push-lock connections that integrate inline with PHOTO-LOC trunk lines and T Cables. No tools or additional adapters are required — it plugs directly into the existing run at the appropriate placement point.

Is the Signal Repeater rated for humid greenhouse environments? +

Yes. The device body, cable, and connectors are all IP67-rated for complete dust protection and resistance to temporary water submersion — making the Signal Repeater fully suitable for the rigorous conditions of commercial indoor farms and greenhouses.

How does EMC suppression help in a grow room environment? +

Commercial grow rooms generate significant electromagnetic interference from LED drivers, HVAC systems, and other high-power equipment. The Signal Repeater's built-in EMC suppression filters out this interference as it restores the signal, preventing noise from corrupting the 0-10V dimming commands passed downstream to your fixtures.
