OVERVIEW
The nLight nPANEL 4 is targeted at rooms that require multiple relays be co-located in a cabinet
enclosure. Utilizing four 30 Amp rated relays, the nPANEL 4 can switch up to four 120/277/347
VAC loads. Further, as a standard feature, the nPANEL 4 pairs a 0-10 VDC dimming output
with each relay. This enables connected loads to be both switched and dimmed as necessary.
Each of the nPANEL 4’s relay/dimming channels can be independently programmed; enabling
custom multi-circuit control applications.

nLIGHT OPERATION
This panel is nLight-enabled, meaning it has the ability to directly communicate over an nLight
network. When daisy-chain wired, using CAT-5 cabling, with other nLight-enabled sensors,
power packs, or WallPods, an nLight control zone is created. Functionally the nPANEL 4
operates as two devices (each with two relays/dimming outputs and a unique network serial
number) that can be utilized together in a single zone or in separate zones. Once linked to a
Gateway, directly or via a Bridge, the zone becomes capable of remote status monitoring and
control via SensorView software.

The nPANEL 4’s onboard power supply provides up to 40 mA of power from each of its RJ-45
(bus) connections and 200 mA via its auxiliary power output. This enables other nLight devices
to connect directly to the nPANEL without any further consideration for device powering.
DEVICE SETTINGS
Several operation settings are available for assignment to each nPANEL relay/dimming pair
independently.
Override (On/Off/Normal)
Occupancy Tracking (Enable/Disable) Photocell Tracking (Enable/Disable) Switch Tracking (Enable/Disable) Switch Tracking Channel (1-16)
Occupancy Tracking Channel (1-16)
Photocell Tracking Channel (1-16)
Invert Relay Logic (Enable/Disable)
Several special modes of operation can also be assigned to each relay/dimming pair that
define the sequence of operation when connected with occupancy sensors or WallPods.
Manual On to Auto Off (Semi-Auto)
Manual to (Timed) Override On
Predictive Off
Auto to (Timed) Override On,
Manual On to Full Auto
DEFAULT SETTINGS
Relay/dimming output 1 => Switch Tracking Channel 1
Relay/dimming output 2 => Switch Tracking Channel 2
Relay/dimming output 3 => Switch Tracking Channel 3
Relay/dimming output 4 => Switch Tracking Channel 4
All relay/dimming outputs => Occupancy Tracking Channel 1
All relay/dimming outputs => Photocell Tracking Channel 1
All relay/dimming outputs => Normal Operational Mode (Auto On/Auto Off)
EMERGENCY POWER APPLICATIONS
Because the relays in the nPANEL 4 are normally closed and latching the unit can be configured
to switch emergency circuits as normal when primary power is present, but then override them
closed when primary power is lost. Note switching both primary and emergency circuits within
the same enclosure is not allowed.
