4 ZONE LIGHTING CONTROLLER WITH PHOTO SENSOR INPUT
AND DRY CONTACT REMOTE OVERRIDE INPUTS
The DLC400BP is a multi-voltage, dedicated 4 zone
lighting controller with photocell input in a NEMA
3 Enclosure. The unit has 30 AMP SPDT heavy duty
contacts, therefore eliminating the need for costly
contactors in most application. Each zone can be
actuated by 1) The photosensor, or 2) Time of day,
or 3) A combination of both. Light level setting at
which lights turn on and off as well as time sched-
ules are assigned independently to each zone, with
the additional capability of remote override inputs
from external switches or local override at the key-
pad.

1. Photo sensor input for all 4 zones each zone

can be controlled through:
A. Time of Day ON/Time of Day OFF
B. Light Level ON/Time of Day OFF
C. Light Level ON/Light Level OFF
2. Remote Input override for all 4 zones
A. Each zone can accept a dry contact closure
for remote override.
B. For timed remote override, use SSA 100/200
Series or A500/C500 Series.
3. Low Voltage (24VDC) supply by the unit to
power low voltage circuits such as occupancy
sensors.
