🚦 70 mm Modular Tower Lights (XVB / XVB7)

Schneider Electric’s 70 mm modular tower lights — mainly the legacy Harmony XVB and next‑generation Harmony XVB7 — are stackable visual and audible signalling columns used to broadcast machine status, warnings, and alarms across a factory floor.

They provide long‑distance visibility, far beyond what panel‑mounted indicators can deliver.

🟦 What They Are

• Modular stack lights where light and sound modules snap together on a single base
• 70 mm diameter for high‑visibility industrial signalling
• Multi‑colour tiers(Green/Amber/Red/Blue/White) for standardised machine states
• Optional audible modules for alarms and alerts

🟧 Key Series

• Harmony XVB — classic modular tower light system
• Harmony XVB7 — next‑gen version with USB, IO‑Link, and vocal/alarm customisation

🟨 Typical Uses

• Machine status indication — running, stopped, fault, maintenance
• Production lines — operator guidance and workflow signalling
• Safety alerts — faults, jams, emergency conditions

⭐ One‑line summary

Schneider Electric’s 70 mm XVB/XVB7 modular tower lights are high‑visibility stackable indicators that broadcast machine status and alarms across industrial environments.
