Lighting Control Relays
Designed for Lighting
The 2-Wire latching relay is the basis of all lighting control systems designed by NexLight.
Relays used for lighting loads undergo some of the harshest loads and for that reason require
the reliability and robustness that the NexLight relays are engineered to provide.
Relay Features
Latching Relays
Once the relay is ON or OFF, it remains in that state, requiring no control power to stay in that
state. The relay will not switch state if the control signal is disabled or disrupted for any reason.
Relay wiring becomes simpler as many relays, switches, and control devices can share the
same common power source (i.e. transformer).
The same relay can easily be controlled from several devices including:
o Wall switches
o Time clocks
o Sensors
o BMS systems
o 3rd party connected devices
Manual Override Lever
Each relay provides a manual switch lever integral to the device and serves dual purposes:
1. Allows the relays to be overridden at the panel which is useful during the installation
phase when switches and controls may not be fully powered or installed.
2. Provides real time highly visible status of the relay.
Mounting
All relays are pre-assembled and pre-wired into NexLight panels. All panels are certified in a
UL508A panel assembly facility. The relays may be installed in master, auxiliary, and remote
mounted panels offering complete versatility in building design.
Approval Bodies
All relays are listed with Underwriters Laboratories (UL) and approved by Canadian Standards
Association (CSA).
Status
All relays provide a status to the NexLight 2-Wire system for transmission to switch status
indication LEDs and monitoring by host sytems.

Relay Controllers
TM
“Extreme Reliability”
Lighting Control Systems
Relay Controllers:
The relay controller provides the interface from the 2-Wire communication bus to the
signals that operate the relay. It also monitors the ON/OFF status of the relay and provides
that information to the NexLight 2-Wire communications bus. Used to control the WR and
CRC series of latching relays.
WRT4014 Relay Controller (4) IR Address Setting
• Addresses are set via infrared (IR) port using handheld programmer unit.
• The prefix and suffix are both set using the handheld programmer.
• Address can be mixed (i.e. can put more than one prefix in controller and
vary the suffix for each output lead).
• 2-Wire communication draw: 2.3 mA
• Weight: 0.187 lbs.
• Dimensions: 3-15/16” L x 1” W x 2.36” H
CRC2000 Relay Controller (4) DIP Address Setting
• Addresses are set via dip switch.
• The prefix (0-63) is set by the dip switch bank on top of the controller and
the suffix is the output lead number (-1, -2, -3, and -4)
• Address cannot be mixed (i.e. the prefix can only be one number and the
suffix is always associated with the corresponding lead).
• 2-Wire communication draw: 2.5 mA
• Weight: 0.125 lbs.
• Dimensions: 2” L x 2” W x 1-5/8” H

Relay Interface

Lighting Control Systems
BBR910 Relay Interface:
The BBR910 relay interface is an input device used to interface any of the WR or CRC series
of latching relays that do not have a built in relay controller to any device that provides a dry
contact closure. Examples of use include: Building Management Systems (BMS), Time
Clocks, Occupancy Sensors, and Non-Intelligent Switches.
• Relay is ON when the dry contact is closed and OFF when the dry contact is open
• Does not require the 2-Wire communications bus
• Can control up to 4 relays at the same time
• If used in conjunction with the two wire bus the two wire bus will still see the changes
• Allows manual override with NexLight hardwire switches that indicate relay position
• Mounts on the WR9910 Mounting Strap
