Overview
Fifth Light’s Relay Panel provides scalable and modular On/Off
control over a lighting panel as part of a DALI system for convenient
control of multiple On/Off loads.
Features
Permits control of standard On/Off luminaires from the integrated
DALI communication interface
Manual and programmable control of each relay via simple web
based software
Factory configured for up to 48 relay capacity
Relay and communication circuitry are fully enclosed for arc flash
protection
Manual override switch sets all relays to the On position
Capable of mixed load voltages as well as mixed sources (i.e.
normal and emergency power)
Rated for Receptacle loads
