Energi Savr Node for 0–10 V­Energi Savr Node with Softswitch

The Energi Savr Node (ESN) family is a group of modular
products for the control of lighting, receptacles, and other loads.
This document describes the following products:

• Energi Savr Node for 0–10 V-
(models QSN-4T20-S, QSN-4T16-S-347)

• Energi Savr Node with Softswitch
(models QSN-4S20-S, QSN-4S16-S-347)

Features

• Rated to switch 20 A receptacles with any output.

• Default configuration requires no commissioning.

• Program using integral interface on the ESN unit.

• Four occupancy sensor inputs for automated control of loads in
4 zones.

• Four daylight sensor inputs automatically adjust light levels based
on the amount of natural light entering through the windows.

• Four IR receiver inputs for personal control.

• Four inputs for IEC PELV / NEC® Class 2 dry-contact switches.

• Includes QS control link for seamless integration of loads, control
stations, and QS sensor modules.

• Patented Softswitch circuit eliminates arcing at mechanical
contacts when loads are switched, prolonging relay life to an
average of 1,000,000 cycles at 16 A.

• Contact Lutron for compatibility with a Quantum system.
